The connection path is Switch-Modem-Link(100M)-Modem-Switch.
The switch is connected to the modem of the WAN link, I think the auto-negotiate may not detect problem from another switch. Also, Will the UDLD work in this situation? Switches are not connected directly.
Bye the way, both of your links points to UDLD documents.
You could use BFD since you want to run routing and this will solve your link down detection issue but the downside is I think BFD can only be used with a Routing protocol. You could also use some other EEM scripts to ping the other sides ip address and after a certain amount of time probably bring down the line protocol though I have never tried this and am not certain if it works. Curious to know the reason why the modem is there if this is a ethernet handoff? Thx
