I have 1 Cisco 2950 (switch A)linked to an HP switch (switch B) which is itself cascaded to a Cisco 2950 (switch C). I have added ip addresses on the 2 cisco switches in VLAN1. Now, switch A can't find B. The linked in on interface F0/1 on A and on port 4 on the HP switch. If I unplug interface F0/1 on A and plug it again, I receive the following error:
inconsistent port type.
Interace F0/1 is blocked on A.
What might be the issue?
Everything was working fine before I change the IP addresses.
