I have an 1841 router with an HWIC-4ESW card in it. I can plug devices into the HWIC and I see the port is up/up. When I try to ping the router Fas0/0 IP from one of the HWIC connected PCs, I cannot ping.
I see no other errors on the card, what am I missing?
All ports are up/up, PC can ping fine if I plug into Fas0/1 instead of Fas0/0/1 (HWIC).
Router works fine otherwise, just cannot seem to get the ports on the HWIC to physically connect to the router Fas0/0 port.
Also, I see the attached PC MAC in my mac-address-table.
No special config, just basically did a no shutdown on the HWIC interfaces.
