The
lacp packet-capture
command captures transmit and receive packets on a single interface. The
contents of these packets can then be displayed by the
show lacp packet-capture
command. If the
lacp
packet-capture
command is not issued, the
show lacp packet-capture
command does not display any
information.

Examples
The following example shows how to display the contents of an LACP packet, in hexadecimal, for a Gigabit
Ethernet interface:
In the following example, after you issue the
lacp packet-capture
command, you must wait for a reasonable
amount of time for the system to capture packets that are sent and received on the interface before you
issue the
show lacp packet-capture
command. Otherwise, there is no information to display.
