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. Refer to “Enabling or Disabling Ports

 

and Configuring Port Mode” on page 10-16.)

 

 

The table on page 12-5describes the maximum number of trunk groups you can configure on the switch. An individual trunk can have up to eight links, with additional standby links if you’re using LACP. You can configure trunk group types as follows:

Trunk Type

Trunk Group Membership

 

TrkX (Static)

DynX (Dynamic)

 

 

 

LACP

Yes

Yes

Trunk

Yes

No

 

 

 

The following examples show how to create different types of trunk groups.
