bandwidth for the trunk. In the next example, ports 1 through 5 have been configured for the same LACP trunk. Notice that one of the links shows Standby status, while the remaining four links are “Up”.

Configure port trunking before you connect the trunked links between

 

switches. Otherwise, a broadcast storm could occur. (If you need to connect

 

the ports before configuring them for trunking, you can temporarily disable

 

the ports until the trunk is configured. See “Using the CLI To Configure Ports”

 

on page 6-8.)

 

 

On the Switches 2512 and 2524, you can configure one port trunk group having up to four links (with additional standby links if you’re using LACP). Options include:

If no trunk group exists, you can create a trunk group on the switch

If a trunk group already exists on the switch, you can add ports to the trunk group or delete ports within the group.

You can remove a subset of ports from a trunk group, or delete the trunk group entirely by removing all ports from the group
