channel-group
Do not configure an EtherChannel in both the PAgP and LACP modes. EtherChannel groups running
PAgP and LACP can coexist on the same switch. Individual EtherChannel groups can run either PAgP
or LACP, but they cannot interoperate.
If you set the protocol by using the channel-protocol interface configuration command, the setting is
not overridden by the channel-group interface configuration command
Do not configure a port that is an active member of an EtherChannel as an 802.1x port. If 802.1x is
enabled on a not-yet active port of an EtherChannel, the port does not join the EtherChannel.
If 802.1x is enabled on a not-yet active port of an EtherChannel in software releases earlier than Cisco
Note
IOS Release 12.2(25)EY, the port does not join the EtherChannel.
Do not configure a secure port as part of an EtherChannel or an EtherChannel port as a secure port.
For a complete list of configuration guidelines, see the "Configuring EtherChannels" chapter in the
software guide for this release.
Do not enable Layer 3 addresses on the physical EtherChannel ports. Do not assign bridge groups on the
Caution
physical EtherChannel ports because it creates loops.
Examples
This example shows how to configure EtherChannel. It assigns ports as static-access ports in VLAN 10
to channel 5 with the PAgP mode desirable.
Switch# configure terminal
Switch(config)# interface range fastethernet1/0/4 -5
Switch(config-if-range)# switchport mode access
Switch(config-if-range)# switchport access vlan 10
Switch(config-if-range)# channel-group 5 mode desirable
Switch(config-if-range)# end

Switch(config-if-range)# switchport mode access
Switch(config-if-range)# switchport access vlan 10
Switch(config-if-range)# channel-group 5 mode active
Switch(config-if-range)# end
You can verify your settings by entering the show running-config privileged EXEC command.
