 CSMs is done on the Catalyst switch using IOS. Every status command for the CSM module is prefixed with show module csm module#. The module# following the keyword csm references the slot in which the module resides. For exam- ple, to see which CSM is active in a fault-tolerance pair, use the show module csm module# ft command: Switch# sho mod csm 8 ft FT group 1, vlan 88 This box is active priority 20, heartbeat 1, failover 3, preemption is on Configuration of CSM modules must be done in CSM configuration mode. To enter CSM configuration mode, use the module csm module# command: Switch(config)# mod csm 8 Switch(config-module-csm)# Common Tasks In a fault-tolerant design with two CSMs connected by a stateful failover link, changes to the primary CSM are not automatically replicated to the secondary CSM. You must replicate the changes manually with the command hw-module csm module# standby config-sync (this command can be executed only on the primary CSM): Switch# hw-module csm 8 standby config-sync Switch# Sep 19 13:02:37 EDT: %CSM_SLB-6-REDUNDANCY_INFO: Module 8 FT info: Active: Bulk sync started Sep 19 13:02:39 EDT: %CSMSLB-4-REDUNDANCYWARN: Module 8 FT warning: ET configuration might be out of sync. Sep 19 13:02:48 EDT: %CSMSLB-4-REDUNDANCYWARN: Module 8 FT warning: FT configuration back in sync Sep 19 13:02:49 EDT: %CSMSLB-6-REDUNDANCY INFO: Module 8 FT info: Active: Manual bulk sync completed The hw-module csm module# standby config-syno command was intro- duced on the CSM in revision 4.2(1), and on the CSM-S (CSM with SSL module) in revision 2.1 (1). A real server might need to be removed from service for maintenance, or because it is misbehaving. To do this, negate the inservice command in the real server configuration: Switch(config)# mod csm 8 Switch(config-module-csm)# real CONTENT-02 Switch(config-slb-module-real)# no inservice The method is the same for real servers, server farms, and vservers. To put the server back into service, remove the no from the inservice command: Switch(config)# mod csm 8 Swi
