2.Repeat the process on the other switch.

RS G8000 (config)# portchannel 1 member 1,7,32

RS G8000 (config)# portchannel 1 enable

#show portchannel

3.Connect the switch ports that will be members in the trunk group.

Trunk group 3 (on the G8000) is now connected to trunk group 1 (on the other switch).

NOTE – In this example, two G8000 switches are used. If a third-party device supporting link aggregation is used (such as Cisco routers and switches with EtherChannel technology or Sun's Quad Fast Ethernet Adapter), trunk groups on the third-party device should be configured manually. Connection problems could arise when using automatic trunk group negotiation on the third-party device.

4.Examine the trunking information on each switch.

#show portchannel information

PortChannel 3: Enabled port state:

2:STG 1 forwarding

23:STG 1 forwarding

30:STG 1 forwarding

Information about each port in each configured trunk group is displayed. Make sure that trunk groups consist of the expected ports and that each port is in the expected state.

The following restrictions apply:

Any physical switch port can belong to only one trunk group.

Up to eight ports can belong to the same trunk group.

All ports in static trunks must be have the same link configuration (speed, duplex, flow control).

Trunking from third-party devices must comply with Cisco® EtherChannel® technology.
