I am having two sup6l-e sup engines in redundancy mode. I have connected the uplink to nexus switch from 3:1 and 4:1 . And somehow now 4:1 is not working . Hence I want to use 4:2 . But it is showing as inactive. How to make that port active?
Those ports will not be active as you have redundant supervisors and there is no way to just active them, is part of the restrictions on redundant mode.
Hope this helps
