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. See “Using the CLI To Configure Ports”
on page 10-10.)
On the switches covered by this guide you can configure up to 24 port trunk
groups having up to 8 links each (with additional standby links if you’re using
dynamic LACP). You can configure trunk group types as follows:
Trunk Type Trunk Group Membership
TrkX (Static) DynX (Dynamic)
LACP Yes Yes
Trunk Yes No
Note Trunks configured as FEC (Fast Ethernet Channel) are not supported. To
configure port trunk groups, use static or LACP trunks. For release notes

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