Note • We strongly recommend that the highest-end, command-capable switch in the cluster be the
command switch:
–
If your switch cluster has a Catalyst 3550 switch, that switch should be the command switch.
–
If your switch cluster has Catalyst 2900 XL, Catalyst 2950, and Catalyst 3500 XL switches, the
Catalyst 2950 should be the command switch.
–
If your switch cluster has Catalyst 1900, Catalyst 2820, Catalyst 2900 XL, and
Catalyst 3500 XL switches, either the Catalyst 2900 XL or Catalyst 3500 XL should be the
command switch.
• Standby command switches must meet these requirements:
–
When the command switch is a Catalyst 3550 switch, all standby command switches must be
Catalyst 3550 switches.
–
When the command switch is a Catalyst 2950 switch running Release 12.1(9)EA1 or later, all
standby command switches must be Catalyst 2950 switches running Release 12.1(9)EA1 or
later.
–
When the command switch is a Catalyst 2950 switch running Release 12.1(6)EA2 or later, all
standby command switches must be Catalyst 2950 switches running Release 12.1(6)EA2 or
later.
–
When the command switch is running Release 12.0(5)WC2 or earlier, the standby command
switches can be these switches: Catalyst 2900 XL, Catalyst 2950, and Catalyst 3500 XL
switches.
We strongly recommend that the command switch and standby command switches are of the same
switch platform and that both are running the same level of software (SI or EI). In the event of a
failover, the standby command switch must support the same configuration and services that are
running on the command switch.
–
If you have a Catalyst 3550 command switch, the standby command switches should be
Catalyst 3550 switches.
–
If you have a Catalyst 2950 command switch, the standby command switches should be
Catalyst 2950 switches.
–
If you have a Catalyst 2900 XL or Catalyst 3500 XL command switch, the standby command
switches should be Catalyst 2900 XL and Catalyst 3500 XL switches.
Refer to the release notes for the Catalyst switches that can be part of a switch cluster.
Note Unless noted otherwise, Table 3-11 lists the menu-bar options available from a Catalyst 2950 command
switch when the cluster contains only Catalyst 2950 member switches. The menu bar of the command
switch displays all menu-bar options available from the cluster, including options from member switches
from other cluster-capable switch platforms.
