Using the show platform forward Command
For more syntax and usage information for the show platform forward command, see the switch
Note
command reference for this release.
Most of the information in the output from the command is useful mainly for technical support
personnel, who have access to detailed information about the switch application-specific integrated
circuits (ASICs). However, packet forwarding information can also be helpful in troubleshooting.
This is an example of the output from the show platform forward command on port 1 in VLAN 5 when
the packet entering that port is addressed to unknown MAC addresses. The packet should be flooded to
all other ports in VLAN 5.

This is an example of the output when the packet coming in on port 1 in VLAN 5 is sent to an address
already learned on the VLAN on another port. It should be forwarded from the port on which the address
was learned.
