channel-group Chapter 2 Catalyst 3560 Switch Cisco IOS Commands channel-group Use the channel-group interface configuration command to assign an Ethernet port to an EtherChannel group, to enable an EtherChannel mode, or both. Use the no 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-group PAgP 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 on Syntax Description channel-group-number mode active auto desirable non-silent on passive Specify the channel group number. The range is 1 to 48. Specify the EtherChannel mode. Unconditionally enable Link Aggregation Control Protocol (LACP). Active mode places a port into a negotiating state in which the port initiates negotiations with other ports by sending LACP packets. A channel is formed with another port group in either the active or passive mode. Enable the Port Aggregation Protocol (PAgP) only if a PAgP device is detected. Auto mode places a port into a passive negotiating state in which the port responds to PAgP packets it receives but does not start PAgP packet negotiation. A channel is formed only with another port group in desirable mode. When auto is enabled, silent operation is the default. Unconditionally enable PAgP. Desirable mode places a port into an active negotiating state in which the port starts negotiations with other ports by sending PAgP packets. An EtherChannel is formed with another port group that is in the desirable or auto mode. When desirable is enabled, silent operation is the default. (Optional) Use in PAgP mode with the auto or desirable keyword when traffic is expected from the other device. Enable on mode. In on mode, a usable EtherChannel exists only when both connected port groups are in the on mode. Enable LACP only if a LACP device is detected. Passive mode places a port into a negotiating state in which the port responds to received LACP packets but does not initiate LACP packet negotiation. A channel is formed only with another port group in active mode. 2-30 Catalyst 3560 Switch Command Reference 78-16405-05
