Usage Guidelines
Use the monitor capture file command only when the storage destination is a file. The file may be stored
either remotely or locally. Use this command after the packet capture has stopped. The packet capture is
stopped when one or more end conditions have been met or you entered the monitor capture stop command.
When WireShark is used on switches in a stack, packet captures can be stored only on the devices specified
for file-location above that are connected to the active switch. Example: flash1 is connected to the active
switch. flash2 is connected to the secondary switch. Only flash1 can be used to store packet captures.
