Disabling a fabric ISL
The no fabric isl enable command takes this interface out of the trunk group if this interface happens to be currently part of the trunk. If you know and would like to fix the edge and fabric port assignments on a switch, then this command allows you to completely turn off ISL formation logic and shorten any link bring-up delays on edge ports.
- Connect to the switch and log in using an account assigned to the admin role.
- Enter the no fabric isl enable command.
