Modifying a Port Trunk
This procedure adds and removes ports from a port trunk.
Caution
Disconnect the cables from the ports of the trunk before you modify
the trunk. Leaving the cables connected can create a loop in the
network topology. A loop can cause a broadcast storm and poor
network performance.
Note
You cannot modify Trunk 7, which is reserved for the uplink ports. If
you want to use the uplink ports as a port trunk, activate Trunk 7 as
explained in “Enabling and Disabling a Port Trunk” on page 65.
