Enabling and Disabling a Port Trunk
This procedure enables and disables a port trunk. Note the following
before performing this procedure:
ˆ Do not enable a port trunk until after you have configured the trunk on
both switches.
ˆ Do not connect the cables to the ports on the switches until after you
have configured and enabled the trunk on both switches.
Caution
Before disabling a port trunk, 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.
