Deployment request
Currently, the deployment of ASON feature versions of OSN products must be
backed up in HQ. The backup application scope covers demonstration, test
and commercial use. Thus, no matter whether the ASON features are
included in the market sales contract, all the ASON features deployment must
be approved through the process. The operation method is as follows: Before the OSN ASON features deployment, the front line customer service
personnel must ask for the HQ approval. The Market department must apply for the ASON features deployment from the HQ. The request must be approved by the manager of OSN PDT.
Before the application of ASON deployment, fill in the version application form, which must be attached with the mail or file formally approved by the OSN PDT manager.
After the version request is approved, the regional office/representative office can use the version to enable the ASON feature.

Some services may be configured on NEs during NE commissioning and
network commissioning. To initialize NEs for deleting the configuration,
perform the initialization before enabling the ASON features. Skip this
step for certain NEs, on which services are operating.
Logical boards must be created before enabling the ASON features. The
logical boards must be identical with the physical boards. If the logical
slots are not created or the logical slots and physical slots are not
identical, data links cannot be generated.
Question:
What channel of LMP protocol is related with the physical slots?

HUAWEI TECHNOLOGIES CO., LTD. Page 15Huawei Confidential
Before setting, query the current configuration. If the
current configuration meets with the requirements,
modification is unnecessary. If not, re-set DCC bytes. You
can query and set the DCC bytes on T2000.
On the Main View, select the target NE. Right-click and select NE
Manager.
Select Communication > DCC Management from the Function Tree.
Select the DCC Resource Allocation tab to set parameters as shown in
the following figure.
Querying/Setting DCC Bytes
HUAWEI TECHNOLOGIES CO., LTD. Page 16Huawei Confidential
You can also query/set the DCC bytes by using the
following command lines: :cm-get-dccpara This command is used to query the DCC channel
allocation mode and use condition.
:cm-get-chanallocinfo This command is used to query the DCC
channel allocation mode provided by the devices.
Or, use the command :cm-get-chanmode to query the DCC channel
allocation mode used by the devices.
:cm-set-dccpara or :cm-set-chanmode The commands are used to set
the DCC channel allocation mode.
After changing the DCC channel allocation mode, you need to soft reset the SCC to validate the settings. If you use T2000 for setting and modification, the NEs automatically soft reset the SCC after you click Apply in the setting window. If you use the command line for setting and modification, you need to manually soft reset the SCC. It is recommended to let NEs automatically soft reset the SCC after setting the NE NODEID in the next step.
Querying/Setting DCC Bytes
HUAWEI TECHNOLOGIES CO., LTD. Page 17Huawei Confidential
Before enabling the ASON features, set the node ID of the ASON NEs.
NODE ID is the unique identity of an NE in the ASON control plane. If
you change the NODE ID after enabling the ASON features, this will
confuse the ASON control plane and as a result services are
interrupted. The features and setting requirements of NODE ID are as
follows: In one ASON domain, the NODE ID cannot be repeated.
The format of NODE ID is x.x.x.x. The parameter x ranges from 1 to 254. The
NODE ID cannot be in the same network segment with the NE IP address.
Set the NODE ID before enabling the ASON software. After the setting, the NE
automatically soft reset the SCC.
After the network is put into use, do not modify the NODE ID. If modification is
required, modify when there are no ASON services. After the modification, note
the ASON NEs adjacent to the soft reset.
Setting NE NODE ID
HUAWEI TECHNOLOGIES CO., LTD. Page 18Huawei Confidential
The following network segments are recommended for
NODEID:
172.16.0.0 — 172.31.255.255 (172.16/12 prefix)
10.0.0.0 — 10.255.255.255 (10/8 prefix)
192.168.0.0 — 192.168.255.255 (192.168/16 prefix)
If the customer wants to select an address out of the recommended
network segments, contact the HQ experts because some addresses
cannot be used as the NODEID.
Use the following commands to query and set the NODEID.
Currently, T2000 does not support this function.
:icon-get-node-id This command is used to query the NODE ID of the local
NE.
:ion-set-node-id This command is used to set the NODE ID of the NE.
After the setting, the NE automatically performs soft reset. )

Enabling ASON Features
After the previous steps are completed, make sure all NEs are
in running state before enabling the ASON features. :cfg-get-nestate This command is used to query whether the NE status is
running.
:cfg-set-itgattrib:enable This command is used to enable the NE ASON
features.
:cfg-get-itgattrib This command is used to query whether the ASON features
are enabled for the NE.
After the ASON features are enabled, you can use the command
to disable the ASON features. The prerequisite for successful
command execution is that the current NE has no ASON
services. If ASON services exist, a failure prompt is returned
after you carry out the command to disable the ASON features. :cfg-set-itgattrib:disable NEs automatically perform soft reset after sending
the command of disabling ASON features.

To avoid the limitation on the number of control
channels in the config_snd status, ASON R2 version
does not create control channels for low-rate line
port (STM-1/4) by default. The low-rate ASON optical
channels must be created manually. The command
lines are shown as follows:
:sc-set-cc-available:Bid,Pid,enable/disable This command is used to
create the control channel of relevant optical ports.
:sc-get-cc-available:0,0 This command is used to query whether the

HUAWEI TECHNOLOGIES CO., LTD. Page 28Huawei Confidential
There are three interfaces related to the OSPF protocol:
Port of the ASON NE connecting to ASON NE fibers
Ethernet port of the ASON NE
Port of the ASON NE connecting to non-ASON NE fibers
The first port uses the OSPF protocol by default but the second port does not. The two ports use the default settings directly. Do not modify them.
The default setting of the third port also uses the OSPF protocol. Because the third port connects with non-ASON NEs, you need to manually disable the OSPF protocol of the port.
Disabling OSPF Protocol
HUAWEI TECHNOLOGIES CO., LTD. Page 29Huawei Confidential
Interface Entry: NE manager/ASON/Advanced maintenance/ASON protocol management
Use the following commands to disable or enable the OSPF protocol of relevant ports:
:lim-set-ospf: bid,pid,0,disable/enable This command is used to disable/enable the OSPF
protocol.
:lim-get-ctrllink:0,0 This command is used to query relevant interfaces of whether the OSPF
protocol is enabled.
Disabling OSPF Protocol
HUAWEI TECHNOLOGIES CO., LTD. Page 30Huawei Confidential
R2 adds the encrypted transfer of RSVP and OSPF message functions, which are mainly to prevent the messages from being listened in or divulged and to improve the network security. For the encryption function of the OSPF and RSVP protocols, it is recommended to use the default values. MD5 certification is the default value of OSPF, and the certification code is AOSV100R002. The default value of RSVP is no certification. Do not modify the default values: If the encryption function is required, pay attention to the following:
Certification support: no certification, simple plain text certification (not
supporting RSVP), MD5 certification
RSVP certification configuration is for nodes and the OSPF certification
configuration is for ports (boards and optical ports). The certification passes
only when the certification configuration of the two nodes are consistent.
Make sure the certification types of OSPFs in the same ASON domain must
be consistent and the RSVP in the same ASON domain must be consistent.

Creating/Modifying ASON Domain
After the NE enables the ASON features and the NMS reload the NE data, query and
open the NE list of the ASON features in the ASON topology management. Make sure
the NMS can normally detect the NEs that already open the ASON features and
modify the ASON domain name based on the actual condition.

HUAWEI TECHNOLOGIES CO., LTD. Page 35Huawei Confidential
Configuring Secondary NE
In the ASON network, each ASON NE stores the topology information of the
entire network. The NMS only needs to communicate with one NE, which is
called "communication NE". Set the Active NE and Standby NE to select the
communication NE. The NMS select the active NE as the communication NE
first. If a fault occurs on the active node, the standby NE acts as the
communication NE.

Creating SRLG (Optional)
Shared risk link group is abbreviated as SRLG. Generally,
fibers in the same cable have the same risk, that is, if the
cable is cut off, all fibers in the cable are cut off. In this
case, the rerouting of ASON services should not be on the
links with the same risk. Thus, correctly set the SRLG for
the links with the same risk in the network.
Interface Entry: Main Menu > Configuration > TE Link

HUAWEI TECHNOLOGIES CO., LTD. Page 40Huawei Confidential
Creating Link Distance (Optional)
When creating ASON trail or rerouting, users need to set the link
distance as required to ensure that the path of long link distance is
not selected during service creation and rerouting.
Interface Entry: Main Menu > Configuration > TE Link

HUAWEI TECHNOLOGIES CO., LTD. Page 41Huawei Confidential
Reserving Link Resources (Optional)
Besides creating ASON services, you can also create traditional services on
the ASON network. Reserving link resources is to reserve partial timeslots
of the links for creating traditional services. The reserved timeslots cannot
be used when creating ASON services or during the ASON services
rerouting. There are two ways to reserve timeslots:
Interface Entry (method one): NE > NE Manager > Functional Tree of
Relevant Boards > ASON > Resource Reservation
The resources are reserved or canceled at the same time on both ends of the link.

Planning MS
Before creating ASON services of any level, confirm the
planning of the multiplex section (MS) and make necessary
service planning. During planning, fully consider the future
expansion requirements and ask for the opinions of the
customer. After reaching an agreement with the customer,
create the multiplex section and then the ASON services.
New functions of multiplex section planning supported by ASON R2 Dynamic add and delete functions of the multiplex section

Creating Tunnel Services
Tunnels also called "ASON trails" are used to carry VC12 or
VC3 lower-order services.
The supported protection types include: gold, silver (non-revertive),
and copper tunnel services.
Currently, only the tunnels of VC4 class are supported; however, VC4
class services cannot be loaded.
The cross-connection from the tributary to the line needs manual
creation and deletion.
When rerouting or optimization occurs on tunnel services, the cross-
connection of the source and sink NEs automatically switch to the new
port without manual interference.
Support converting tunnel services to the channel of static service
layer.

Association services are similar to diamond services, and used for the
service containing two access points. An association service remembers the
peer LSP ID to associate two common services. During the rerouting or
optimization of an LSP, the remove strategy of 1+1 route is adopted to avoid
secondary associated LSP; thus, co-bearing a service to improve the
protection level.
Support the association between silver services, between copper services, and between
silver services and copper services.
Support the service association between the same or different source and sink nodes, and support the association between silver tunnels, between copper tunnels and between silver tunnels and copper tunnels. Two two-end tunnels can be associated. Two single-end tunnels of the same time (indicating the source or sink single-end) can also be associated.
The association of diamond services is not supported, and neither is the association of gold services.

Conditions of gold service restriction: Make sure the timeslots of gold services are consistent on the ring.
For gold services on the same ring, there are two ways to restrict
the route:
a. Perform loose constraint on the service head node.
b. Perform strict constraint on the intermediary node.
For gold services crossing multiplex segment ring, you can loosely
specify a cross-ring node as the compulsory node.

Service Optimization
After many changes of the topology, the LSP of each service on the ASON optical network is not the optimized. In this case, the optimization function is provided.
Optimization is to create an LSP, switch the optimized services to the new
LSP, and delete the original LSP. That is to say, optimization is to change and
optimize the service route without interrupting services.
When you are optimizing the ASON trail, you can only change the passed
route and timeslot without changing the level and other attributes of the ASON
trail.
Service types supporting the optimization function include: diamond service,
gold service, silver service, copper service, iron service, associated service
and tunnel service.

HUAWEI TECHNOLOGIES CO., LTD. Page 87Huawei Confidential
The migration from gold ASON services to diamond, silver and copper
services is complex, but the migration can still be performed without
disturbing services. The operation is as follows: If the original service is gold service, to convert to diamond, silver or copper
service, the service must be optimized to a non-protection trail. Degrade the
gold service to static service, change the attribute of the permanent service
(such as adding SNCP protection) and then upgrade relevant permanent
service to the destination ASON service.
If the original service is diamond, silver or copper service, degrade the ASON
service to permanent service. Then, adjust the service time slot or adjust, add
or delete MS based on the actual condition. The objective is to let permanent
service run on the working timeslot of the MS and then upgrade the relevant
permanent service to gold service.

ASON solutions provided by Huawei can help the OptiX OSN optical
transmission devices OSN9500, OSN7500, OSN3500, OSN2500 and
OSN1500 to easily upgrade from the traditional NE to the ASON NE.
In general, the methods for commissioning the ASON features with services
enabled and commissioning new ASON features are not greatly different.
The methods and procedures are roughly the same. The impact of ASON
features with service enabled is mainly embodied on the reconstruction of
the traditional network; for example, the requirement of two SCC boards,
the change of networking form, the change of the protection subnet and the
adjustment of the services.
Traditional Network with Services Enabled Upgrading to ASON Network

Upgrade of product software version
Requirements on SCC boards of high
performance
Requirements on T2000 license update
If the traditional NMS T2000 does not support the ASON features, you
need to ask the customer to purchase new T2000 license that supports
the ASON features again.
Version requirements: T2000 V200R004 or later
The same as the software and main
control requirements of ASON (R2)
Key Points
HUAWEI TECHNOLOGIES CO., LTD. Page 98Huawei Confidential
Network re-planning For the ASON with service enabled, the network planning and ASON service
planning must be finished before the implementation.
The ASON network is typically networked in MESH mode while the traditional
network is typically networked in ring and link mode. Thus, consolidating and using
current network resources is important. Besides, fiber resources should be added
accordingly for the sake of the ASON network features.
The expansion of partial lines (as required) may relates to the adjustment of board
insertion timeslot.
Re-plan the existing MS based on the actual condition. The ASON R2 version does
not support 1+1 linear MS on the ASON network.
Backing up NE database Before enabling the ASON features, back up the NE database to avoid rollback after
an NE enables the ASON features.
Key Points
HUAWEI TECHNOLOGIES CO., LTD. Page 99Huawei Confidential
Impact on NE attribute settings Allocation of DCC channels:
For the current version of OSN3500&2500&1500, if the DCC channel uses D4-
D12 bytes, the number of DCC channels using D1-D3 bytes will be reduced
accordingly.
NODEID planning:
Before enabling ASON features, the NodeID and IP (including NE IP and IP
used by inner network) in the entire ASON domain must be planned uniformly
to prevent conflicts.

Diamond service switchover
Switching time < 50 ms. Mount meters on both ends to solve the timeout
problem. The diamond services adopt two-end switching. If the loop test is
adopted, the 37718 meter will be unable to identify that the switching is
performed twice.
Gold service
Switching time < 50 ms. The switching test timeout problem also exists. Mount
meters on both ends to solve this problem.
