Switchback; Port Redundancy Cli Commands - Avaya G250 Administration

Configuring advanced switching

Switchback

If switchback is enabled and the primary port recovers, a switchback takes place. Use the set
port redundancy-intervals command to set the following switchback parameters:
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 none, there is no switchback
to the primary port 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 G250 and Avaya G350 CLI Reference, 03-300437.
Use the set port redundancy enable/disable command to globally enable or
●
disable the redundancy pairs you have defined. Using this command will not delete
existing redundancy entries.
Use the set port redundancy on/off command to define or remove redundancy
●
pairs. Use the show port redundancy command to ensure that there is no redundancy
scheme already defined on any of the links.
Use the set port redundancy-intervals command to configure the two time
●
constants that determine redundancy switchover parameters.
Use the show port redundancy command to display information about software port
●
redundancy schemes defined for the switch.
Note:
If you configure the Ethernet LAN port on the G350 front panel to be redundant
Note:
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 set port
redundancy-intervals command with the switchback interval parameter set
to 0.
