History of Solved CTS Cases
The following list refers to open cases in the Change Tracking System 'CTS'.
This Build Series 2018-01-12
12622 Deadlock at boot up when syslog tries to log to a remote host
When syslog is configured to log to a remote host using a host name, the DNS resolution could
generate a deadlock at boot up. The device would then end up in an endless reboot.
This issue has been resolved and now syslog remote host name DNS resolution cannot
generate deadlock anymore.
12624 Privacy not handled if P-Preferred-Identity or P-Asserted-Identity header is missing
The Privacy header was ignored if the P-Preferred-Identity or P-Asserted-Identity header was
missing. In this case no Privacy header was set in the outgoing SIP packet. Now the outgoing
packet has the Privacy header set if it is present on the incoming packet or if a P-Asserted-
Identity or P-Preferred-Identity header is present.
Build Series 2017-09-11
12619 Penalty box triggers action script on target reachability
The penalty box of a SIP interface can be configured to periodically check the reachability of the
remote by sending SIP OPTIONS. This feature can be used to avoid timeouts when sending the
SIP INVITE message.
Two new Action Script events are also generated with the penalty box feature:
1. OPTIONS_TARGET_REACHABLE
2. OPTIONS_TARGET_NOT_REACHABLE
The first event is triggered when the Patton Device receives an answer to the SIP OPTIONS
request sent to the remote for the first time. The second event is triggered when the first event
has already been triggered and no answer is received to the SIP OPTIONS request.
These two new Action Script events can be used to change the configuration dynamically
according to the reachability of SIP remotes. See the New Configuration Commands section for
more details.
12620 E1 MFR2 call dropped with Argentina profile
In Argentina metering pulses might be sent over MFR2. The Smartnode did not recognize these
metering pulses and treated them as ClearBackward signal, which was the cause of the
dropped call.
Rev. 1.00 07-03-18 4/31
Now the Smartnode, when configured to use Argentina R2 profile, recognizes these metering
pulses and ignores them.
12631 Upgraded DSP firmware for SN494x/5x/6x/7x/8x/9x, SN548x/9x and SN466x/7x devices
For SN494x/5x/6x/7x/8x/9x and SN548x/9x devices the VoIP-stream processing DSP has been
upgraded to version 700.36 and for SN4666x/7x devices to version 700.25.
12633 SIP call with relayed T.38 fax transmission failed
Under the following conditions a SIP-to-SIP T.38 fax call would fail when the SIP Re-INVITE to
T.38 is received:
codec negotiation is disabled in the voip profile
"fax transmission relay t38-udp" is configured in the voip profile.
No final response to the Re-INVITE is ever sent. The call is ultimately terminated by the peer
with a BYE request.
12637 SIP call IP-IP codec negotiation with unsupported codec in ReINVITE did not work
If codec negotiation is enabled, a SIP-to-SIP would fail when a SIP Re-INVITE with an
unsupported codec is received.
Instead of rejecting the unsupported codec with a SIP 488 error message, no final response to
the Re-INVITE is ever sent.
Build Series 2017-05-08
12585 Increased Number of Retries for HTTP Provisioning
For provisioning locations using the HTTP protocol, the files and resources are downloaded by
issuing an HTTP request to the server. When this initial request is not answered by the server
within 3 seconds, the request is repeated. This could happen up to 3 times with a maximum
time of 12 seconds until the HTTP connection is terminated. Because this time is too short for
certain applications providing dynamic resources, the number of retries has been increased to 9
for a total time of up to 30 seconds until the connection is terminated.
12595 Crash on DNS Lookup of SIP Trusted Host Names
In the SIP interface it is possible to configure a list of trusted hosts. Incoming calls which are not
originating from these trusted hosts are not accepted on the corresponding interface. Because a
trusted host can be specified as host name it needs to be resolved into an IP-Address before
the trust of an incoming SIP call can be verified. Up until now the resolution of a trusted host
name happened after the reception of the INVITE request. Because the resolution with the DNS
system itself can take some time, this could lead to delays of calls or crashing the device.
Rev. 1.00 07-03-18 5/31
Therefore trusted host names configured in SIP interfaces are now resolved with the DNS
system upon configuration and continuously kept up-to date. As a consequence incoming SIP
calls do not need to wait before the trust can be verified.
12600 Presentation-Indicator and Screening-Indicator from diversion header have random
values and cannot be changed
PI and SI from diversion header had random values and they could not be changed using a
mapping table. They could not be used in a routing table either.
Now PI and SI are correctly initialized and properly set in the diversion header. We can also
create mapping tables to change their values.
12603 Upgraded DSP firmware for SN494x/5x/6x/7x/8x/9x, SN548x/9x and SN466x/7x devices
The DSP firmware has been upgraded to version 700.23.
12605 Web GUI - Spelling errors in the SIP Interface 'call-transfer' section
Corrected spelling errors in „Telephony > Call-Router > Interface > SIP > (choose any SIP
interface) > Configuration > Call-Transfer‟:
1. "Accept" with description „Accepts REFER messagss from the connected user agent‟,
should be "messages" instead of "messagss".
2. “Pull-In” with description „Detects external call loops and connects intern through‟, should
be “internally” instead of “intern”.
12615 Wrong Codec negotiated for SIP to SIP Call
When receiving an INVITE with twice the same codec type inside the SDP, the intersection
logic let slip a wrong codec from the local configured voip profile into the resulting list, breaking
codec negotiation for SIP to SIP calls.
Build Series 2017-03-14
12580 Deny VLAN configuration when port dsl is in ATM mode
A user was able to configure the dsl port with VLANs when ATM encapsulation was set.
However, the results do not show up in the running-config. This is because VLANs are not
supported in ATM mode.
This change allows the configuration of VLANs only when the port dsl is in EFM mode.
12590 Crash at bootup due to „exit‟ command in the configuration
The device crashed if, while parsing a hand-crafted startup-config at bootup, an „exit‟ command
was parsed which tried to exit from the configuration mode. This could happen if the
configuration contains an invalid mode command, in which case the consecutive „exit‟ command
is not executed inside that mode, but in the next higher level mode.
Rev. 1.00 07-03-18 6/31
Now a warning message is printed into the event log if this case arises.
12596 Support for the SN-DTA/2BIS2V4HP/EUI model
Support for the SmartNode model SN-DTA/2BIS2V4HP/EUI has been introduced. Only
software equal to or newer than Build Series 2017-03-14 must be loaded for proper operation of
this device.
12597 Error on command low-bitrate-codec
Due to recent changes in hardware and software the command „low-bitrate-codec‟ has become
obsolete on certain products because the DSP supports both low bitrate codecs (g723 and
g729) at the same time. For these products the command had been removed from the software.
This caused CLI parsing errors for existing configurations containing the command. These
errors did not have an impact on the proper functioning of the device.
In order to avoid any false errors reports, the command „low-bitrate-codec‟ is again accepted on
these products. It is simply ignored where not needed and it does not appear in the running-
config either.
12598 SmartNode devices occasionally crashed when processing mis-ordered rtp-map
telephony-event
Fixed an issue where SmartNode devices crashed in rare cases of SIP-to-SIP calls (back-to-
back user-agent scenario). The problem occurred when a peer sent SDP responses with the
telephony-event rtp-map in a different order than the corresponding payload-type.
12599 EFM interface drops all packets with certain non-FCS-capable DSLAMs
Some DSLAMs expect the CPE to remove Frame-Check Sequence (FCS) from all Ethernet
packets. So far, the EFM port configured in ATM mode did not remove the FCS. Most DSLAMs
configured in non-FCS mode were still fine with this, but some older DSLAMs did not accept the
packet. As a consequence, the PPPoE over ATM connection could not be established even
though the link was up. More precisely, the PADI frames that the Patton device sent in the
PPPoE discovery stage were dropped by the DSLAM.
In order to be compatible with the few restrictive DSLAMs a new configuration command has
been added in the “port dsl” mode. The “[no] fcs” command configures whether the Patton
device shall send Frame-Check Sequences (FCS) (default: on). See the New Configuration
Commands section for more details.
12601 Memory-leak when sending CANCEL message over SIP
For every CANCEL request sent over SIP, SmartWare lost a small part of its memory. Due to
the small size of the memory leak, there was no immediate impact. Over time the memory
fragmentized and caused the memory manager to slow down. This could have a negative
impact on the call performance and ultimately lead the device into an unresponsive state where
no calls would be processed anymore.
Rev. 1.00 07-03-18 7/31
Build Series 2016-12-29
11215 Endless call-waiting on second call (FXS)
When a second incoming call was waiting on an FXS interface, this second call was dropped
after 15 seconds and the call-waiting indication “beep-tone” to the party in call, receiving the
second call, heard only 2 beeps.
Now the call-waiting timeout is infinite. This means that the second call remains in ringing state
until the caller gives up or the called party answers this call. Furthermore the call-waiting
indication "beep-tone" to the called party is also played until the call is answered or the call is
given up.
12435 Quoted SIP diversion-header parameters were ignored
Quoted parameters of received SIP diversion headers were ignored and the device's default
parameters were used instead. The SIP stack now properly parses and processes SIP
diversion-headers parameters, whether they are quoted or not.
12573 Endless dial tone on second call (FXS)
When a call was put on hold on an FXS interface, the user heard the dial tone for 7 seconds
only and afterwards the call was released and the release tone played. As a consequence the
“address-completion timeout” had no effect if it was set to a value greater than 7 seconds (12
seconds by default).
Now the dial tone timeout is infinite and effective if the user configures “no address-completion
timeout” in the configuration mode “context cs”. Otherwise the configured “address-completion
timeout” takes precedence and terminates the played dial tone when expired (12 seconds by
default).
12574 Ignored the recorded-units parameter in a SIP INFO AOC header
Fixed an issue where the device ignored the 'recorded-units' parameter of a received SIP INFO
message with an AOC header.
12576 SmartNode sent wrong response after a SIP ReINVITE with unsupported codecs
When the SmartNode received a SIP ReINVITE with unsupported codecs, it responded
correctly with a '488 Not Acceptable' message. However, if the device received another SIP
ReINVITE later with supported codecs, it failed and responded with a '100 Trying' message.
Now, the device correctly responds with a '200 OK' message to a SIP ReINVITE with supported
codecs after a ReINVITE with unsupported codecs.
12578 SIP handover on RTP loss with Hunt-Group
The overall use-case is to provide a fallback for SIP calls. The configuration of the different
destinations is done by creating multiple SIP interfaces and routing calls to them from a hunt-
Rev. 1.00 07-03-18 8/31
group service. A new command for specifying how the fallback calls are referencing to the
original call is added. See the New Configuration Commands section for more details.
This feature requires the sip-handover license.
12579 Unable to exit from the configuration mode „port dsl‟
Fixed an issue whereby the “exit” command in the configuration mode “port dsl” was missing on
all products with the EFM interface.
12586 Provisioning now supports HTTP chunked transfer-encoding
Some web servers are always using chunked encoding to transfer data to the client,
independently of the amount of bytes that have to be transmitted.
SmartWare now supports HTTP based provisioning using Transfer-Encoding chunked.
Build Series 2016-11-15
12540 Support HTTP without Content-Type header
When doing provisioning with HTTP locations or issuing a file download with the copy command
from HTTP, then the file could be only downloaded successfully when the server added in its
answer a Content-Type header.
With this implementation SmartWare now assumes a default content type of "text/plain". This
allows to provision and copy from HTTP servers which do not always add a Content-Type
header.
12551 RTP payload-type translations for DTMF RFC2833 events
When no DSP was involved, for example in a Session Border Controller, the RTP payload type
for DTMF RFC2833 events was tunneled even if the configured payload-type on one side was
different from the other side. Now the RTP payload-type for DTMF RFC2833 events always
matches the configuration of the corresponding VoIP profiles.
12560 Fallback to G.711 when T.38 fax is rejected in 200 OK
Improved interoperability in a specific T.38 scenario:
1. The SmartNode is configured to send T.38 fax and to fall back to G.711 in the case the
peer does not support T.38.
2. The peer does not support T.38 but instead of rejecting the offer with a 4xx, it rejects it
by setting the port to zero in the SDP of the 200 OK.
If these conditions are met, the SmartNode will now re-INVITE with a G.711 offer.
12567 SIP UPDATE mid-dialog fails
Rev. 1.00 07-03-18 9/31
In a SIP UPDATE message that is received mid-dialog, the SDP content was not interpreted
correctly and resulted in an error in most cases. The call was subsequently terminated with a
BYE request immediately after reception of the UPDATE message.
Build Series 2016-09-13
12526 SDP support for SIP UPDATE
Support for codec renegotiation after receiving a SIP UPDATE with SDP content has been
implemented.
What to expect - For an UPDATE coming during an Early-Dialog, the SmartNode will answer:
If the call is SIP-TDM (i.e. transcoding, ending calls locally) -> 200 OK, and will update
codecs and privacy headers.
If the call is SIP-SIP (ip-ip codec negotiation) -> 491 Request Pending, and will not
update anything.
If the call is SIP-SIP and the UPDATE message does NOT include SDP -> 200 OK, and
will update only privacy headers.
For an UPDATE coming Mid-Dialog, the SmartNode will answer:
If the call is SIP-TDM (i.e. transcoding, ending calls locally) -> 200 OK, and will update
codecs but not privacy headers (not needed).
If the call is SIP-SIP (ip-ip codec negotiation) -> It will trigger RE-INVITE codec
renegotiation with the peer and will forward back its answer (i.e. 200 OK, 488 Not
Acceptable Here).
If the call is SIP-SIP and the UPDATE message does NOT include SDP -> 200 OK, and
will update only privacy headers.
12549 Improve feedback for invalid provisioning locations
The provisioning profile allowed specifying archive files as provisioning locations. These led
then to failures in the provisioning with misleading error descriptions. Now the configuration of
these locations itself is denied to make it clear that these are not supported at all.
12550 Start SIP re-registration after half of the expiry time
SmartWare started SIP re-registrations only short before the actual registration expiry time. In
some cases the time needed for DNS resolution lead to an expiration of the registration before
the renewal was completed. Therefore the behavior is now changed to start the re-registration
after half of the expiry time, to have enough time for renewal before the registration actually
expires.
12553 PPP LCP magic number not random
Rev. 1.00 07-03-18 10/31
The SmartNode‟s magic number negotiated with PPP LCP was not determined randomly. The
magic number is used to detect link loops, so it should be changed for new connections. Now
the magic number changes to a new random value for every new connection attempt.
12554 PPP LCP MRU cannot be forced above the underlying link MTU
In some rare situations the LCP MRU must be configured to 1500 even though the actual link
MTU is smaller (e.g. 1492 bytes). One reason for this is when a PPPoE connection is
terminated by two L2TP-chained BRAS (Cisco and Juniper, see http://www.gossamer-
threads.com/lists/cisco/nsp/71142); one of the BRAS will drop PPP frames if the MRU is not
negotiated to the tunnel MTU, which typically is at 1500 bytes.
SmartWare already provides a configuration command in the PPP profile to force the MRU to
1500 bytes: mru min 68 max 1500 default 1500 ignore-link
However, the ignore-link parameter, which should force the MRU to the specified value despite
any underlying link restriction, only worked for the max but not for the default parameter. Now
SmartWare correctly negotiates an MRU of 1500 with the command above.
12555 PPP LCP Echo-Request payload size cannot be configured
In some rare situations the payload of LCP Echo-Requests must be greater than zero bytes:
One such case is if the SmartNode creates a PPPoE connection over the EFM-DB in ATM
mode to a BRAS that does not pad the Ethernet frames. In this case very small ATM cells are
dropped, including Echo Requests without payload. We changed the default payload size from
0 to 8 bytes and made the payload-size configurable with the lcp-echo-request command
in the PPP profile (see “New Configuration Commands” section below).

Caveat - Known Limitations
The following list refers to open cases in the Change Tracking System 'CTS'
CTS2236
Only G.723 high rate (6.3kbps) supported by H.323 (receive and transmit).
CTS2702
TFTP may not work with certain TFTP servers, namely the ones that change the port number in the reply.
When using the SolarWinds TFTP server on the CD-ROM this problem will not occur.
CTS2980
With 10bT Ethernet ports, only the half duplex mode works. (With 10/100bT Ethernet ports, all
combinations work.)
CTS3233
The SolarWinds TFTP server version 2.2.0 (1999) does not correctly handle file sizes of n * 512 Bytes.
Use version 3.0.9 (2000) or higher.
CTS3760
The SIP penalty-box feature does not work with TCP. When the penalty box feature is enabled, the TCP
transport protocol must be disabled using the „no transport tcp‟ command in the SIP gateway
configuration mode.
CTS3924
Changing a call-progress tone has no effect. Adding a new call-progress tone and using it from the tone
set profile works however.
CTS4031
The Caller-ID message length on FXS hardware with Chip Revision numbers below V1.5 is restricted to
32 bytes. If the message is longer the message will be truncated. The FXS Chip Revision can be
displayed using the „show port fxs detail 5‟ CLI command.
CTS4038
When doing 'shutdown' and then 'no shutdown' on an ethernet port that is bound to an IP interface that
receives its IP address over DHCP, the IP interface does not renew the lease.
CTS4077
Using the command „terminal monitor-filter‟ with regular expressions on systems under heavy load can
cause a reboot.
CTS4335
The duration of an on-hook pulse declared as flash-hook has been raised from 20ms to 1000ms, to
cover the most country specific flash hook durations. Existing installations should not be affected, as all
on-hook pulses lower than 1000ms are declared as flash-hook, including the previous default of 20ms.
Rev. 1.00 07-03-18 24/31
However, care should be taken in analog line extension applications, to make sure that the flash-hook
event is allowed to be relayed over SIP or H.323. This can be achieved by disabling all local call
features in the fxs interface on context cs: no call-waiting, no additional-call-offering, no call-hold.
CTS10392
The internal timer configuration command is only able to execute commands that produce an immediate
result. Some commands that execute asynchronously cannot be executed by the timer. The following
commands (among others) cannot be executed by the timer:
ping
traceroute
dns-lookup
copy any kind of files from or to a TFTP server
reload without the forced option
CTS10553
The command “no debug all” does not fully disable the ISDN debug logs. As soon as any other ISDN
debug monitor is enabled, all the ISDN monitors that were disabled by “no debug all” are re-enabled.
CTS10586
The codecs G.723 and G.729 cannot be used at the same time on all platforms, except on the
SmartNode 4960.
CTS10610
SmartNode 4960 Gigabit Ethernet does not properly work with Dell 2708 Gigabit Ethernet Switch. A
work-around is to configure 100Mbit.
CTS10730
Due to memory limitations it is not possible to download a software image to the SN4552 when two SIP
gateways are active.
CTS11114
On SN46xx units it can happen that there are more open phone calls requiring a DSP channel than
DSP channels are available. This leads to the situation where a phone connected on a bri port rings and
has no voice after the user picks it up. To limit the number of calls using DSP channels it is suggested
to create a limiter service where each call from and to a bri port has to pass. When the total number of
calls on the bri ports is limited to the number of DSP channels each call is going to have audio on
picking up.
CTS11786
On older SmartNodes the two debug monitors debug media-gateway rtp and debug call-control print out
incorrect RTCP jitter values.
CTS11816
Rev. 1.00 07-03-18 25/31
The command „call-control call drop <call>‟ is not behaving as expected. It drops all calls but does not
completely teardown all internal structures. Consequently the call numbers of the dropped call cannot
be used anymore for further calls after executing this command. The same is true for the “Drop all”
button on the web interface on the “Active Calls” tab of the Call-Router section.
CTS12027
The following configuration may create duplicate packets: If one physical ethernet port is bound to two
IP interfaces with different IP addresses and on both IP interfaces a SIP gateway is bound and some
static routes are configured, then the SIP gateways may receive duplicate UDP packets.
Rev. 1.00 07-03-18 26/31
New Configuration Commands
The commands documented in the Release Notes only cover new additions which are not yet included in
the Software Configuration Guide for R6.9, available from www.patton.com.
https://www.patton.com/manuals/SmartWare_SCG_r69.pdf
Current Revision:
Part Number: 07MSWR69_SCG, Rev. A
Penalty box triggers action script on target reachability
First appeared in build series: 2017-09-11
Action scripts can be configured to trigger an event when the SIP OPTIONS target is not reachable
anymore.
1. First configure the penalty-box
Mode: context cs <cs-name>
Command Purpose
Step 1 node(ctx-cs)[<cs-name>]# interface sip <ifName>
Creates/Enters a SIP interface.
Step 2 node(if-sip)[<cs-name>.<if-name>]# penalty-box sip-option-trigger interval <interval> timeout <timeout>
Enables the penalty-box with SIP OPTIONS.
2. Then configure the Action Script
Mode: actions
Command Purpose
Step 1 node(act)# rule <name> Creates/Enters an actions script rule.
Step 2 node(act)[<name>]# condition cs sip:<if-name> { OPTIONS_TARGET_NOT_REACHABLE | OPTIONS_TARGET_REACHABLE }
Enter the condition in which the following action(s) have to be executed.
Step 3 node(act)[<name>]# action <command> Enter the action to execute when the
condition above is met.
EFM interface drops all packets with certain non-FCS-capable DSLAMs
First appeared in build series: 2017-03-14
Rev. 1.00 07-03-18 27/31
The EFM port of Patton devices (if configured in ATM mode) always sent Frame-Check Sequences
(FCS) with Ethernet frames (for PPPoE). While most DSLAMs in bridged-non-fcs mode still accept
frames with FCS, some DSLAMs strictly drop FCS frames. For those cases, the following CLI command
can be used to remove FCS from sent Ethernet frames.
Mode: port dsl <slot> <port>
Command Purpose
Step 1 node(prt-dsl)[<slot>/<port>]# [no] fcs Configures whether a Frame-Check
Sequence (FCS) is added to the sent Ethernet frames if the port operates in ATM mode (default: enabled). (Some DSLAMs configured in bridged-non-fcs mode discard PPPoE frames with an FCS attached.)
SIP handover on RTP loss with Hunt-Group
First appeared in build series: 2016-12-29
The overall use-case is to provide a fallback for SIP calls. The configuration of the different destinations is
done by creating multiple SIP interfaces and routing calls to them from a hunt-group service. The hunt-
group does its normal hunt operation until the call can be established.
When the handover is configured, the hunt-group remains in the call and provides a fallback mechanism
if the RTP connection is lost. The hunt-group then establishes a new call to the next destination with the
objective to replace the call with the broken RTP connection. If that new call is routed to SIP, it is going to
have a Replaces header in the INVITE message to signal the handover to the involved SIP server. No
audio data is streamed to the originating user until the media of the new call is fully connected.
The old established call with the broken media connection is terminated once the new call has been
established for a few seconds.
Note: This feature requires the sip-handover license. The detection of broken media connection only
works for SIP calls. The Replaces information is only present if the fallback destination is a SIP server.
Mode: context cs <name>/service hunt-group <name>
Command Purpose
Step 1 node(svc-hunt)[<name>]# call-handover on-media-loss
Configures the hunt-group to stay in the call and issuing a replacement call when a loss of RTP stream is detected. Requires license: sip-handover. Default: disabled.
In addition the time for RTP loss detection can be configured:
Mode: profile voip <name>
Rev. 1.00 07-03-18 28/31
Command Purpose
Step 1 node(pf-voip)[<name>]# media loss-detection <ms>
Configures the time in milliseconds since the last received RTP packet until the media connection is considered broken. Default: 1000 ms. Range: 1000-10000 ms.
If the new call is routed to SIP, the reference to the old call can be signaled in the INVITE message to the
SIP server in different ways:
With a Replaces header: The new call has a Replaces header according to RFC 3891. This is the default signaling method.
o Replaces: cab569ce83a9026ab;from-tag=1854a30e67;to-tag=6b357f4fa3
With Patton specific headers: The new call has two proprietary headers, one signaling the handover with "true" and one to provide the value of the Call-ID header from the old call.
o X-Patton-Call-Failure: true
o X-Patton-Call-ID: cab569ce83a9026ab
No signaling: No specific information about the old call is added to the new call‟s INVITE message.
Mode: context cs <name> / interface sip <name>
Command Purpose
Step 1 node(if-sip)[<name>]# [no] call-handover signaling (replaces-header | patton-header)
Configures how the new call provides information about the old call. Default: replaces-header.

General Notes
Factory Configuration and Default Startup Configuration
The SmartNodes as delivered from the factory contain both a factory configuration and a default
startup configuration. While the factory configuration contains only basic IP connectivity settings, the
default startup configuration includes settings for most SmartWare functions. Note that if you press and
hold the system button (Reset) for 5 seconds the factory configuration is copied onto the startup
configuration (overwrite). The default startup config is then lost.
IP Addresses in the Factory Configuration
The factory configuration contains the following IP interfaces and address configurations bound by the
Ethernet ports 0/0 and 0/1.
interface eth0
ipaddress dhcp
mtu 1500
interface eth1
ipaddress 192.168.1.1 255.255.255.0
mtu 1500

How to submit Trouble Reports
Patton makes every effort to ensure that the products achieve a supreme level of quality. However due to
the wealth of functionality and complexity of the products there remains a certain number of problems,
either pertaining to the Patton product or the interoperability with other vendor's products. The following
set of guidelines will help us in pinpointing the problem and accordingly find a solution to cure it.
Problem Description:
Add a description of the problem. If possible and applicable, include a diagram of the network
setup (with Microsoft tools).
Product Description:
When reporting a problem, always submit the product name, release and build number.
Example: SmartNode 4960 V1 R6.T Build 2018-01-12
This will help us in identifying the correct software version.
In the unlikely case of a suspected hardware problem also submit the serial number of the
SmartNode (s) and/or interface cards.
Running Configuration:
With the Command Line Interface command 'show running-configuration' you can display the
currently active configuration of the system (in a telnet and/or console session). When added to
the submitted trouble report, this will help us analyze the configuration and preclude possible
configuration problems.
Logs and Protocol Monitors:
Protocol traces contain a wealth of additional information, which may be very helpful in finding or at
least pinpointing the problem. Various protocol monitors with different levels of detail are an
integral part of SmartWare and can be started (in a telnet and/or console session) individually
('debug' command).
N.B.: In order to correlate the protocol monitors at the different levels in SmartWare (e.g. ISDN
layer3 and Session-Router monitors) run the monitors concurrently.
Network Traffic Traces:
In certain cases it may be helpful to have a trace of the traffic on the IP network in order to
inspect packet contents. Please use one of the following tools (supporting trace file formats
which our tools can read): Ethereal (freeware; www.ethereal.com)
Your Coordinates:
For further enquiries please add your email address and phone number.
