Secondary Port Activation; Switchback; Port Redundancy Cli Commands - Avaya G350 Administration

Secondary port activation

The secondary port takes over within one second and is activated when the Primary port link stops
functioning. Subsequent switchovers take place after the minimum time between switchovers has
elapsed. To set the minimum time between switchovers, use the
command.

Switchback

If switchback is enabled and the Primary port recovers, a switchback takes place. Use the
redundancy-intervals
•
min-time-between-switchovers — the minimum time that is allowed to elapse before a Primary-
Backup switchover
•
switchback-interval — the minimum time the Primary port link has to be up before a switchback
to the Primary port takes place. If you set this to
when it recovers. In this case, switchback to the Primary port only takes place if the Secondary
port fails.

Port redundancy CLI commands

The following commands are used to configure port redundancy. For more information about these
commands, see Avaya G350 Media Gateway CLI Reference, 555-245-202.
•
Use the
redundancy pairs you have defined. Using this command will not delete existing redundancy
entries.
•
Use the
show port redundancy
on any of the links.
•
Use the
determine redundancy switchover parameters.
•
Use the
schemes defined for the switch.
NOTE:
If you configure the Ethernet LAN port on the G350 front panel to be redundant with the
Gigabit Ethernet port on the MM314 Media Module, the Ethernet LAN port becomes the
primary port after resetting the G350 even if you configured the Gigabit Ethernet port to
be primary. To prevent this, use the
switchback interval parameter set to 0. For example:
G350-003(super)# set port redundancy 6/3 6/5 on 1
Monitor: Port 6/5 is redundant to port 6/3.
