Module6: EtherChannel(New Terms and Commands)

show interfaces port-channel

this command displays the general status of the port channel interface.

show etherchannel summary

displays one line of information per port channel

show etherchannel port-channel

displays information about a specific port channel interface

show interfaces etherchannel

provide information about the role of the interface in the EtherChannel

interface port-channel X

change settings on the specified port channel interface

channel-group X mode [desirable, auto, active, passive]

creating the port channel interface

LACP passive

This LACP mode places a port in a passive negotiating state. In this state, the port responds to the LACP packets that it receives but does not initiate LACP packet negotiation.

LACP active

This LACP mode places a port in an active negotiating state. In this state, the port initiates negotiations with other ports by sending LACP packets.

PAgP auto

This PAgP mode places an interface in a passive negotiating state in which the interface responds to the PAgP packets that it receives but does not initiate PAgP negotiation.

PAgP desirable

This PAgP mode places an interface in an active negotiating state in which the interface initiates negotiations with other interfaces by sending PAgP packets.

PAgP

aids in the automatic creation of EtherChannel links

LACP

part of an IEEE specification (802.3ad) that allows several physical ports to be bundled to form a single logical channel.

Port Channel

When an EtherChannel is configured, the resulting virtual interface is called

EtherChannel

grouping several Fast Ethernet or Gigabit Ethernet ports into one logical channel.

link aggregation

groups multiple physical Ethernet links together into one single logical link.
