supervisor syncing

[suthomas1]

All,

On a 6500 chasis, housing two supervisor engines, one of them is faulty and other is working fine.

How do we replace the faulty one on the chasis when the new replacement comes from configuration part ?

Since the new one will act as standby engine for the existing one, should i be loading the required IOS and just inserting the new engine on to the chasis, so it tries to sync up with primary supervisor engine. or do i need to manually configure it.

thanks.

Hi,

You can remove the fault supervisor engine and place the new one.
And you need to load the exact IOS what you have on the active supervisor engine.

By default on the Cisco Catalyst 6500 Series, the Catalyst OS software images on the active and the standby supervisor engines must be the same. This allows the system to maintain a stable operating environment by ensuring that the supervisor engine switchover occurs with the same software features and revisions on the new active supervisor engine as on the previously active supervisor engine. If the two supervisor images are not the same version during system bootup, the active supervisor engine downloads its current boot image to the standby supervisor engine. The NVRAM configuration of the active supervisor engine is also synchronized between the supervisor engines.

Please see the below link for procedure to follow replace supervisor engine.

how should the configuration part on the replacement be done. Will it sync with the primary supervisor if i load the required IOS and slot it in as hot swappable .

thanks.

Hi,

Once the IOS is same on the active and standby supervisor module the config to NVRAM will be automatically replicate from active to standby.
