Hello Jaspreet, I am not 100% sure what the problem is here but my best
guess is the following ...
I have read somewhere about a switching scenario, I think it was MLS where
very bizarre ARP issues occur. I recall that MAC addresses were learned
from multiple interfaces and this caused problems. I'm not 100% sure of
this so don't humiliate me. I belive that the "WRONG CABLE" message you're
getting means that your switching process has learned about a MAC/IP address
combination from a certain interface and in a short space of time is also
learned from a different interface. The message is saying "I just learned
about that MAC address from interface FE 1/1/0 and now I'm learning it from
FE 0/0/0, somethings wrong here!"
regards
Ki

me what the "WRONG CABLE" means in the following debug output
