Chapter 27      Configuring EtherChannel and Link State Tracking
Displaying EtherChannel to a Virtual Switch System
This example shows how to remove Fast Ethernet interfaces 5/4 and 5/5 from port channel 1:
Switch# configure terminal 
Switch(config)# interface range fastethernet 5/4 - 5 (Note: Space is mandatory.)
Switch(config-if)# no channel-group 1 
Switch(config-if)# end 
Removing an EtherChannel
If you remove an EtherChannel, the member ports are shut down and removed from the channel group.
Note If you want to change an EtherChannel from Layer 2 to Layer 3, or Layer 3 to Layer 2, you must remove 
the EtherChannel and recreate it in the desired configuration.
To remove an EtherChannel, perform this task:
This example shows how to remove port channel 1:
Switch# configure terminal 
Switch(config)# no interface port-channel 1 
Switch(config)# end 
Displaying EtherChannel to a Virtual Switch System
Catalyst 4500 series switches support enhanced PAgP. If a Catalyst 4500 series switch is connected to a 
Catalyst 6500 series Virtual Switch System (VSS) by using a PAgP EtherChannel, the Catalyst 4500 
series switch automatically serve as a VSS client, using enhanced PAgP on this EtherChannel for 
dual-active detection. This VSS client feature has no impact on the performance of Catalyst 4500 series 
switch and does not require any user configuration.
This section includes these topics:
• Understanding VSS Client, page 27-21
• Displaying EtherChannel Links to VSS, page 27-23
Step 3
Switch(config-if)# end 
Exits configuration mode.
Step 4
Switch# show running-config interface 
{fastethernet | gigabitethernet | 
tengigabitethernet} slot/port 
Switch# show interface {fastethernet | 
gigabitethernet | tengigabitethernet} slot/port 
etherchannel 
Verifies the configuration.
