Configuring Frame Relay Autosynchronization LMI Sequence Numbers
The autosynchronization procedure is only for devices supporting Frame Relay and is optional. To configure Frame Relay SSO to synchronize LMI sequence numbers between the active and standby RSPs, use the following command in global configuration mode.
Command | Purpose |
|
|
Router(config)# | Configures automatic synchronization of Frame |
Relay LMI sequence numbers between the active RSP | |
| and the standby RSP. |
|
|
Verifying SSO
To verify that SSO is configured on the networking device, use the show redundancy command. To verify that the device is running in SSO mode, use the show redundancy states command. The show redundancy states command specifies whether the unit is running in SSO mode, which is indicated by
STANDBY HOT.
