Configuring advanced switchingSwitchbackIf switchback is enabled and the primary port recovers, a switchback takes place. Use the setport redundancy-intervals command to set the following switchback parameters:●●min-time-between-switchovers — the minimum time that is allowed to elapse before aprimary-backup switchoverswitchback-interval — the minimum time the primary port link has to be up before aswitchback to the primary port takes place. If you set this to none, there is no switchbackto the primary port when it recovers. In this case, switchback to the primary port only takesplace if the secondary port fails.Port redundancy CLI commandsThe following commands are used to configure port redundancy. For more information aboutthese commands, see Avaya G350 Media Gateway CLI Reference, 555-245-202.●●●●Use the set port redundancy enable/disable command to globally enable ordisable the redundancy pairs you have defined. Using this command will not deleteexisting redundancy entries.Use the set port redundancy on/off command to define or remove redundancypairs. Use the show port redundancy command to ensure that there is no redundancyscheme already defined on any of the links.Use the set port redundancy-intervals command to configure the two timeconstants that determine redundancy switchover parameters.Use the show port redundancy command to display information about software portredundancy schemes defined for the switch.Note:Note:If you configure the Ethernet LAN port on the G350 front panel to be redundantwith the Gigabit Ethernet port on the MM314 Media Module, the Ethernet LANport becomes the primary port after resetting the G350 even if you configured theGigabit Ethernet port to be primary. To prevent this, use the set portredundancy-intervals command with the switchback interval parameter setto 0.140 Administration of the Avaya G350 Media Gateway
