Access to Older Switches In a Cluster

If your cluster has these member switches running earlier software releases and if you have read-only
access to these member switches, some configuration windows for those switches display incomplete
information:
•Catalyst 2900 XL or Catalyst 3500 XL member switches running Cisco IOS R ele ase 12. 0(5)WC 2
or earlier
•Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or e arli er
For more information about this limitation, refer to the release notes.
These switches do not support read-only mode on CMS:
•Catalyst 1900 and Catalyst 2820 switches
•Catalyst 2900 XL switches with 4-MB CPU DRAM
In read-only mode, these switches appear as unavailable devices and canno t be c onfigure d fro m CM S.
