Command History
Usage Guidelines If you do not specify a value for the channel-group argument, all channel groups are displayed.
If the interface is configured as part of the channel in ON mode, the show etherchannel protocol
command displays Protocol: - (Mode ON).
• In the output of the show etherchannel summary command, the following conventions apply:
• In the column that displays the protocol that is used for the channel, if the channel mode is ON, a
hyphen (-) is displayed.
For LACP, multiple aggregators are supported. For example, if two different bundles are created, Po1
indicates the primary aggregator, and Po1A and Po1B indicates the secondary aggregators.
In the output of the show etherchannel load-balance command, the following conventions apply:
• For EtherChannel load balancing of IPv6 traffic, if the traffic is bridged onto an EtherChannel (for
example, it is a Layer 2 channel and traffic in the same VLAN is bridged across it), the traffic is
always load balanced by the IPv6 addresses or src, dest, or src-dest, depending on the configuration.
For this reason, the switch ignores the MAC/IP/ports for bridged IPv6 traffic. If you configure
src-dst-mac, the src-dst-ip(v6) address is displayed. If you configure src-mac, the src-ip(v6) address
is displayed.
• IPv6 traffic that is routed over a Layer 2 or a Layer 3 channel is load balanced based on MAC
addresses or IPv6 addresses, depending on the configuration. The MAC/IP and the src/dst/src-dst
are supported, but load balancing that is based on Layer 4 ports is not supported. If you use the port
keyword, the IPv6 addresses or either src, dst, or src-dst, is displayed.
channel-group (Optional) Number of the channel group. If you do not specify a value for
the channel-group argument, all channel groups are displayed.
