channel-groupChapter 2Catalyst 3750-E and 3560-E Switch Cisco IOS Commandschannel-groupUse the channel-group interface configuration command on the switch stack or on a standalone switchto assign an Ethernet port to an EtherChannel group, to enable an EtherChannel mode, or both. Use theno form of this command to remove an Ethernet port from an EtherChannel group.channel-group channel-group-number mode {active | {auto [non-silent]} | {desirable[non-silent]} | on | passive}no channel-groupPAgP modes:channel-group channel-group-number mode {{auto [non-silent]} | {desirable [non-silent}}LACP modes:channel-group channel-group-number mode {active | passive}On mode:channel-group channel-group-number mode onSyntax Description channel-group-number Specify the channel group number. The range is 1 to 48.modeSpecify the EtherChannel mode.activeUnconditionally enable Link Aggregation Control Protocol (LACP).Active mode places a port into a negotiating state in which the port initiatesnegotiations with other ports by sending LACP packets. A channel isformed with another port group in either the active or passive mode.autoEnable the Port Aggregation Protocol (PAgP) only if a PAgP device isdetected.Auto mode places a port into a passive negotiating state in which the portresponds to PAgP packets it receives but does not start PAgP packetnegotiation. A channel is formed only with another port group in desirablemode. When auto is enabled, silent operation is the default.desirableUnconditionally enable PAgP.Desirable mode places a port into an active negotiating state in which theport starts negotiations with other ports by sending PAgP packets. AnEtherChannel is formed with another port group that is in the desirable orauto mode. When desirable is enabled, silent operation is the default.non-silent(Optional) Use in PAgP mode with the auto or desirable keyword whentraffic is expected from the other device.onEnable on mode.In on mode, a usable EtherChannel exists only when both connected portgroups are in the on mode.passiveEnable LACP only if a LACP device is detected.Passive mode places a port into a negotiating state in which the portresponds to received LACP packets but does not initiate LACP packetnegotiation. A channel is formed only with another port group in activemode.2-78Catalyst 3750-E and 3560-E Switch Command ReferenceOL-9776-08
