Auto-advise and auto-copy identify which images are running by examining the info file and by searching
the directory structure on the switch stack. If you download your image by using the
copy tftp: boot loader
command instead of the archive download-sw privileged EXEC command, the proper directory structure
is not created. For more information about the info file, see the Catalyst 2960-X Switch Managing Cisco
IOS Image Files Configuration Guide .
Note
SDM Template Mismatch in Switch Stacks
The LAN Base default template is used with switches in a homogeneous stack, and the LAN Base routing
template is used with switches in a mixed stack.
All stack members use the Switch Database Management (SDM) template configured on the active switchstack
master. When a new switch is added to a stack, the SDM configuration that is stored on the active switchstack
master overrides the template configured on an individual switch.
When you add a Catalyst 2960-S switch to a stack of Catalyst 2960-X switches running the LAN Base default
template, the Catalyst 2960-S switch will go into SDM-mismatch mode. You must change the template of
the switch stack to the LAN Base routing template.
You can use the show switch privileged EXEC command to see if any stack members are in SDM-mismatch
mode.
Version-mismatch (VM) mode has priority over SDM-mismatch mode. If a VM-mode condition and an
SDM-mismatch mode exist, the switch stack first attempts to resolve the VM-mode condition.
For more information about SDM templates, see the Catalyst 2960-X Switch System Management Configuration
Guide .
Switch Stack Management Connectivity
You manage the switch stack and the stack member interfaces through the active switchstack master. You
can use the CLI, SNMP, and supported network management applications such as CiscoWorks. You cannot
manage stack members on an individual Switch basis.
Connectivity to Specific Stack Members
If you want to configure a specific stack member port, you must include the stack member number in the CLI
command interface notation.
To debug a specific stack member, you can access it from the stack master by using the session
stack-member-number privileged EXEC command. The stack member number is appended to the system
prompt. For example, Switch-2# is the prompt in privileged EXEC mode for stack member 2, and the system
prompt for the stack master is Switch. Only the
show and debug commands are available in a CLI session to
a specific stack member.
To debug the standby switch, you can access it from the active switch using the session standby ios privileged
EXEC command. To debug a specific stack member, use the session switch stack-member-number privileged
EXEC command from the active switch to access the diagnostic shell of the stack member. Only the show
and debug commands are available in a CLI session to a specific stack member.
