Catalyst 3750 Switch Show Platform Commands
This appendix describes the show platform privileged EXEC commands that have been created or changed for use with the Catalyst 3750 switch. These commands display information helpful in diagnosing and resolving internetworking problems and should be used only under the guidance of Cisco technical support staff.
show platform acl
Use the show platform acl privileged EXEC command to display platform-dependent access control list (ACL) manager information.
show platform acl {interface interface-id | label label-number [detail] | statistics asic-number | vlan vlan-id} [ | {begin | exclude | include} expression]

These are the states displayed in the summary information about the switch stack:
•Waiting—The stage when a switch is booting up and waiting for communication from other switches in the stack. The switch has not yet determined whether it is a stack master or not.
Stack members not participating in a stack master election remain in the waiting state until the stack master is elected and ready.
•Initializing—The stage when a switch has determined whether it is the stack master or not. If the switch is not the stack master, it is receiving its system- and interface-level configuration from the stack master and loading it.
•Ready—The stage when the stack member has completed loading the system- and interface-level configuration and is ready to forward traffic.
•Master Re-Init—The stage immediately after a stack master re-election and a different stack member is elected stack master. The new stack master is re-initializing its configuration. This state applies only to the new stack master.
•Ver Mismatch—The stage of a switch in version mismatch (VM) mode. VM mode is when a switch joining the switch stack has a different stack protocol minor version number from the stack master.
A typical state transition for a stack member (including a stack master) booting up is Waiting -> Initializing -> Ready.
A typical state transition for a stack member becoming a stack master after a stack master election is Ready -> Master Re-Init -> Ready.
A typical state transition for a stack member in version mismatch (VM) mode is Waiting -> Ver Mismatch.
