Fully redundant three-member stack (Figure 5):
C2960-FullRedundant#show switch stack-ports
Switch # Port 1 Port 2
-------- ------ ------
1 Ok Ok
2 Ok Ok
3 Ok Ok
C2960-FullRedundant#show switch neighbors
Switch # Port 1 Port 2
-------- ------ ------
1 2 3
2 3 1
3 1 2
Nonredundant three-member stack (Figure 6):
C2960-NonRedundant#show switch stack-ports
Switch # Port 1 Port 2
-------- ------ ------
1 Ok Down
2 Ok Ok
3 Ok Down
C2960-NonRedundant#show switch neighbors
Switch # Port 1 Port 2
-------- ------ ------
1 2 None
2 1 3
3 2 None
The master of the stack will be the one management interface for the entire stack. All IP communications (that is,
Telnet, SSH, SNMP, ping, HTTP, and so on) will be handled by the master regardless of the member the
communication ingressed the stack. All console activity regardless of media (RJ45 or USB) is directed to the
master regardless of the member to which the console port is connected.
The Cisco Catalyst 2960-S, 2960-X, and 2960-XR support the CISCO-STACKWISE-MIB for managing switch
stacks. This is the same MIB that the Cisco Catalyst 3750, 3750-E, and 3750-X Series Switches support.
Figure 5: All stack ports are
operational.
Shows the member number of the
neighbor on a stack link.
For example, member 1 connects
to member 2 on port 1 and member
3 on port 2.
Figure 6: Not All stack ports are
operational.
Member 1 connects only to member 2 on port
1. Member 2 connects to Member 1 on Port 1,
and member 3 on port 2.
