Chapter 28 Configuring EtherChannels and Layer 2 Trunk Failover Configuring EtherChannels Step 3 Step 4 Step 5 Step 6 Step 7 Command Purpose switchport mode {access | trunk} switchport access vlan vlan-id Assign all ports as static-access ports in the same VLAN, or configure them as trunks. If you configure the port as a static-access port, assign it to only one VLAN. The range is 1 to 4094. channel-group channel-group-number mode Assign the port to a channel group, and specify the PAgP or the {auto [non-silent] | desirable [non-silent] | on} | LACP mode. {active | passive} For channel-group-number, the range is 1 to 48. For mode, select one of these keywords: • auto-Enables PAgP only if a PAgP device is detected. It places the port into a passive negotiating state, in which the port responds to PAgP packets it receives but does not start PAgP packet negotiation. • desirable-Unconditionally enables PAgP. It places the port into an active negotiating state, in which the port starts negotiations with other ports by sending PAgP packets. • on-Forces the port to channel without PAgP or LACP. In the on mode, an EtherChannel exists only when a port group in the on mode is connected to another port group in the on mode. • non-silent-(Optional) If your switch is connected to a partner that is PAgP-capable, configure the switch port for nonsilent operation when the port is in the auto or desirable mode. If you do not specify non-silent, silent is assumed. The silent setting is for connections to file servers or packet analyzers. This setting allows PAgP to operate, to attach the port to a channel group, and to use the port for transmission. • active-Enables LACP only if a LACP device is detected. It places the port into an active negotiating state in which the port starts negotiations with other ports by sending LACP packets. • passive-Enables LACP on the port and places it into a passive negotiating state in which the port responds to LACP packets that it receives, but does not start LACP packet negotiation. For information on compatible modes for the switch and its partner, see the "PAgP Modes" section on page 28-4 and the "LACP Modes" section on page 28-5. end Return to privileged EXEC mode. show running-config Verify your entries. copy running-config startup-config (Optional) Save your entries in the configuration file. To remove a port from the EtherChannel group, use the no channel-group interface configuration command. OL-8915-01 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide 28-11
