channel-group
In this case, running PAgP on a physical port prevents that port from ever becoming operational.
However, it allows PAgP to operate, to attach the port to a channel group, and to use the port for
transmission. Both ends of the link cannot be set to silent.
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.
You should exercise care when setting the mode to on (manual configuration). All ports configured in
Caution
the on mode are bundled in the same group and are forced to have similar characteristics. If the group is
misconfigured, packet loss or spanning-tree loops might occur.
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.
PAgP and LACP are available only on NNIs and ENIs.
Note
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 or a not-yet-active member of an EtherChannel as an
IEEE 802.1x port. If you try to enable IEEE 802.1x on an EtherChannel port, an error message appears,
and IEEE 802.1x is not enabled.
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 configuration guide for this release.
Caution
Do not enable Layer 3 addresses on the physical EtherChannel ports. Do not assign bridge groups on the
physical EtherChannel ports because it creates loops.
Examples
This example shows how to configure an EtherChannel. It assigns two static-access ports in VLAN 10
to channel 5 with the PAgP mode desirable:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 -2
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
This example shows how to configure an EtherChannel. It assigns two static-access ports in VLAN 10
to channel 5 with the LACP mode active:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 -2
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.
