CSM Configuration replication

Scenerio:

We have 2 6509's with CSM's (ver 4.2(3)) each in slot 4, setup for failover via

interface GigabitEthernet3/1

switchport

switchport access vlan 257

switchport mode access

no ip address

These are Full-duplex, 1000Mb/s

(same on each)

Problem: when we execute a "wr" to the primary, it is not replicating to the secondary even though it says it is:

VOC-SW15#wr

Building configuration...

4w6d: %PFINIT-SP-5-CONFIG_SYNC: Sync'ing the startup configuration to the standby Router[OK]

VOC-SW15#

4w6d: %CSM_SLB-6-REDUNDANCY_INFO: Module 4 FT info: State Transition Standby -> Active

The sych command replicates the secondary successful:

hw-module csm 4 standby config-sync

Here is some info on the configs:

VOC-SW15#sh mod csm 4 ft

FT group 2, vlan 257

This box is active

priority 20, heartbeat 1, failover 3, preemption is on

alternate priority 30

VOC-SW15#

We are still in the process of setting these CSM's up. They are not yet in production:

VOC-SW15#sh run mod 4

Since manual synch is working, I'm not sure if our connection is correct (not trunk) or if we are missing required statement.

Also, if anyone has any suggestions on reading material concerning the CSM's, please send a link. I'm finding the Cisco links more confusing than I have on any product in the past.

Any suggestions are appreciated. Thank you, Sheila

Re: CSM Configuration replication

The 'wr mem' command does not synch the CSM.

Only the "hw-module csm 4 standby config-sync" will do.

This is normal behavior.

Re: CSM Configuration replication

Thanks Gilles. Is there a different configuration that will do this? It was a function of the Local Director's failover, which we are retiring. Sheila

Re: CSM Configuration replication

Sheila,

I'm not sure what you are looking for.

The command to synch the CSM config is the 'hw-module...' command that you have already used.

There is no other command to achieve this function.
