FLEXAMINER: RECOMMENDATIONS
Time synchronization
FlexAminer and client must be time synhronized
NTP server configuration
Open a telnet/ssh session on FlexAminer (login: admin)
Go to network menu and then to ntp sub menu
Set the ntp1 server
Quit the sub-menu and valid modification
Set time
If there does not exist any NTP server, set UTC time on FlexAminer
read current date & time : utc_date
set new date & time (UTC) : utc_sdate

FLEXAMINER: RECOMMENDATIONS
Network configuration
Flextream Out Of Band case
The IGMP Querier address of the switch connected to Eth1 (NIC2) is in the same network
than Eth1 (IP@/ Netmask)
Flextream In Band case
The IGMP Querier address of the switch connected to Eth0 (resp. Eth2) is in the same
network than Eth0 (resp. Eth2) (IP@/ Netmask)
Eth0 (NIC1) and Eth2 (NIC3) are connected to 2 different IP switches with different IGMP
Querier addresses
Eth0 and Eth2 are not in the same network
Read IGMP Querier IP address
Use ssh/telnet session as admin user
Example with eth1
15
Igmp query network = 198.18.128.1

Service analysis
This view allows user to know for the service
How many times video bitrate is closed to MAX video bitrate set in MXS
bitrate >= MAX bitrate – n%
It could be interesting to set n% to know how many times bitrate >= specific bitrate
(=MAX- n%)
How many times video bitrate is closed to MIN video bitrate set in MXS
bitrate <= MIN bitrate + n%
How many times video bitrate is far from MAX & MIN video bitrates set in MXS
MIN bitrate + n% < bitrate < MAX bitrate – n%
The metric can be allocated bitrate
or requested bitrate
The percentage « n %» can be set
by user among global settings
