I have two Cisco 7206 routers in my network. According to Nav the modules in these routers continuously goes up and down. Each module is almost always declared as down in 5 hours, then it's declared as up again for one hour, before it's declared as down again.. Of course the modules are up all the time.

Unfortunately I did not have access to any Cisco devices I could remove/add modules from when I wrote the Module Monitor code, thus this part is not very well tested (I did have access to 3Com and HP devices, so that part is somewhat better tested).

If Morten has access to some Cisco equipment in a test lab perhaps he can check how these devices actually behave when a module goes down.
