Enabling and Disabling a Port Trunk
This procedure enables and disables a port trunk. Note the following
before performing this procedure:
 Do not enable a port trunk until after you have configured the trunk on
both switches.
 Do not connect the cables to the ports on the switches until after you
have configured and enabled the trunk on both switches.
Note
If you are disabling a port trunk, be sure to first disconnect all cables
from the ports of the trunk. Leaving the cables connected can create
loops in your network topology because the ports of a disabled port
trunk function as normal network ports, forwarding individual
network traffic.
