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 Enable or Disable
Ports and Configure Port Mode” on page 10-9.)
The table on page 13-4 describes the maximum number of trunk groups you
can configure on the switches covered in this guide. 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
Note Trunks configured as FEC (Fast Ethernet Channel) are not supported. To
configure port trunk groups, use static or LACP trunks. For release notes
