Figure 6-9. Example of a Dynamic LACP Trunk with One Standby Link
Using the CLI To Configure a Static or Dynamic Trunk Group
I m p o r t a n t
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 6-6.)
On the SMC6624M, you can configure one port trunk group having up to four
links (with additional standby links if you’re using LACP). Options include:
■
If no trunk group exists, you can create a trunk group on the switch
■
If a trunk group already exists on the switch, you can add ports to the
trunk group or delete ports within the group.
■
You can remove a subset of ports from a trunk group, or delete the trunk
group entirely by removing all ports from the group
