Operating System Support

The CSM is supported on switches running both the Catalyst operating system on the supervisor engine
and Cisco IOS on the MSFC. The CSM is also supported on switches running Cisco IOS on both the
supervisor engine and the MSFC.
Because the CSM is configured through the MSFC CLI, if you are using a switch running both the
Catalyst operating system and Cisco IOS, you must first session into the MSFC for access to the MSFC
CLI, from where the CSM is configured. When you access the MSFC CLI, the CSM configuration is
identical for the Catalyst operating system and Cisco IOS switch.
All the Layer 2 configurations (such as VLAN and port associations) are performed on the supervisor
engine when using a switch running both the Catalyst operating system and Cisco IOS.
Note When running the CSM on a switch with only the Cisco IOS software, configured VLANs are
automatically added to the trunk or channel that connects the CSM to the switch backplane. In a switch
running both the Catalyst operating system and the Cisco IOS software, you will have to manually add
the CSM VLANs to the trunk or channel.
