Using the CLI To Configure a Static or Dynamic 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. Refer to “Enabling or Disabling Ports
and Configuring Port Mode” on page 10-11.)
The table on page 12-5 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
Trunk
Yes Yes
Yes No
The following examples show how to create different types of trunk groups.
