interface interface-type interface-number [ to interface-type interface-number ]: 
Specifies a port or ports. The command without the parameter to specifies one 
port, while the command with the parameter to specifies several contiguous 
ports. interface-type indicates port type. interface-number indicates port number. 
For more information, see the parameter description of the interface command.

Use the debugging lacp packet command to enable LACP packet debugging for 
the port. If you do not specify a port, the command enables packet debugging on 
all LACP-enabled ports.

Use the undo debugging lacp packet command to disable LACP packet 
debugging for the port.

# Enable LACP packet debugging for Ethernet port Ethernet1/1/1.
