Migrating Between Modes; Differences Between Csm And Rp Modes; Csm Mode - Cisco catalyst 6500 series Configuration Note

Chapter 3 Getting Started

Migrating Between Modes

Existing CSM configurations are migrated to the new configuration when the mode is changed from
CSM to RP using the ip slb mode command. If a CSM configuration exists, you are prompted for the
slot number.
You can migrate from an RP mode configuration to CSM mode configuration on the Catalyst 6500 series
switch. You can migrate manually only from a Cisco IOS SLB configuration to a CSM configuration.

Differences Between CSM and RP Modes

The CSM and RP modes only affect the way in which the CSM is configured from CLI, not the operation
and functionalities of the CSM itself. The RP mode is required to configure multiple CSMs in one
chassis as well as the Cisco IOS SLB in the same chassis with a CSM.

CSM Mode

You can use the ip slb mode csm command mode to configure a CSM in 1.x releases. This mode allows
the configuration of a single CSM in the chassis (other CSMs or Cisco IOS SLB cannot be configured
in the same chassis).
In this mode, all the CSM configuration commands begin with ip slb.
CSM show commands begin with show ip slb.
This mode is not recommended if you are using CSM 2.1 or later releases, where it is provided as an
option in the Cisco IOS CLI for backward compatibility.
The following is an example of a configuration for a single CSM in the chassis:
