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".)
"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
Trk
X
(Static)
Dyn
X
(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
Removing ports from a static trunk group
CAUTION:
Removing a port from a trunk can create a loop and cause a broadcast storm. When you
remove a port from a trunk where spanning tree is not in use, The switch recommends that you first
disable the port or disconnect the link on that port.
Syntax:
no trunk <
port-list
>
Removes the specified ports from an existing trunk group.
Example:
To remove ports C4 and C5 from an existing trunk group:
