Configuration synchronisation not working on redundant SUP1A with MSFC


I have to WS-X6K-SUP1A-MSFC. The active in slot 1, the standby in slot2. Both SUP1A are running cat OS 6.4.3. On both MSFC are running 12.1(13)E6 enterprise plus with VIP software (JSV). On the active MSFC the config are as follows:




the other options I can use in high-availability is config-sync. If I configure this, it show me "HA Single Router Mode is on. Config sync is implied". Other commands who are in the documentation, like auto-sync and so on are not possible to configure. The active MSFC is running well but there is no config synchronistation to the stanby MSFC. The status of the redunancy is as follows.

MSFC-RT1#sh red

Designated Router: 1 Non-designated Router: 2

Redundancy Status: designated

Config Sync AdminStatus : disabled

Config Sync RuntimeStatus: disabled

Single Router Mode AdminStatus : enabled

Single Router Mode RuntimeStatus: disabled

Single Router Mode transition timer : 120 seconds


How can I configure redundancy for the MSFC configuration? Where are the commands documented?

Looks like you have enabled SRM. The config looks good and when the active MSFC fails, the standby's interfaces should go active. Are you having any issues?

Re: Configuration synchronisation not working on redundant SUP1A

I installed a new supervisor in the slot2 (redundant). The images and the config of the from the supervisor was copyied from the active to the standby. But the standby supervisor show me the default prompt (Router>) no config. Is it not in that way if the redundant supervisor has a problem I can replace the standby module with a new clean one and all the images and configs are downloaded and syncronized with the active one?

Re: Configuration synchronisation not working on redundant SUP1A

If you have installed a new supervisor the MSFC card on the module will have the default config.

What you need to do is first disable the SRM mode on the active MSFC and then configure the secondary MSFC to use the SRM (or whichever mode you want) then go back to the active MSFC and enable the SRM again. They should then syncronize. Check the log for the event.

The MSFC configuration is not copied automatically to the new MSFC when you install a new supervisor/MSFC. This only happens with the switch e.g. the CatOS version and config are synchronized.
