Configuring a static trunk or static LACP trunk group

IMPORTANT:

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 "Enabling or Disabling Ports and Configuring Port Mode".)

The "Port trunk features and operation" section describes 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.

Syntax:


trunk < port-list > < trk1 ... trk60 > {<trunk | lacp>}

Configures the specified static trunk type.

Example:

This Example: uses ports C4 to C6 to create a non-protocol static trunk group with the group name Trk2.

switch(config)# trunk c4-c6 trk2 trunk
