Chapter 30 Configuring EtherChannels
Displaying EtherChannel, PAgP, and LACP Status
Note If LACP is not able to aggregate all the ports that are compatible (for example, the remote system might
have more restrictive hardware limitations), all the ports that cannot be actively included in the
EtherChannel are put in the hot-standby state and are used only if one of the channeled ports fails.
Beginning in privileged EXEC mode, follow these steps to configure the LACP port priority. This
procedure is optional.
To return the LACP port priority to the default value, use the no lacp port-priority interface
configuration command.
Displaying EtherChannel, PAgP, and LACP Status
To display EtherChannel, PAgP, and LACP status information, use the privileged EXEC commands
described in Table 30-4:
You can clear PAgP channel-group information and traffic counters by using the clear pagp
{channel-group-number counters | counters} privileged EXEC command.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the port to be configured, and enter interface configuration
mode.
Step 3
lacp port-priority priority Configure the LACP port priority.
For priority, the range is 1 to 65535. The default is 32768. The lower the
value, the more likely that the port will be used for LACP transmission.
Step 4
end Return to privileged EXEC mode.
Step 5
show running-config
or
show lacp [channel-group-number]
internal
Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.

information.
show pagp [channel-group-number] {counters |
internal | neighbor}
Displays PAgP information such as traffic information, the
