primary and backup link stuff

It will depend on the IP address you are polling. It sounds like you're polling the IP address of the interface of the primary link. You need to poll something that will always be up such as a Loopback interface.

The IP address of the primary link is different from loopback address. How to configure at solarwinds when the primary link is down and the cellular backup kicked in, the node indicator would still be green?

interface Loopback100

ip address 172.29.7.21 255.255.255.255

end

interface Serial0/1/0

ip address 10.63.205.130 255.255.255.252

ip virtual-reassembly in

encapsulation frame-relay IETF

no fair-queue

frame-relay interface-dlci 135

frame-relay lmi-type ansi

end

What IP address are you using to monitor the node? Is it 172.29.7.21?

If yes, how does the cellular backup work? Can you still telnet to the router whilst it's running on the cellular backup?

Yes its 172.29.7.21. If the cellular backup kicked in, i still can't telnet the router.

Does the cellular backup not use IP? Sorry I don't know how the cellular backups work.

Yes the cellular backup does have an IP address its Cellular0/0/0  10.49.180.138. So what can i do with it? Is there a script on SolarWinds to do this?

Can you telnet to that IP when it's running on the backup? Or even when it's not?

You may have to post up your config as I can't see why the loopback interface becomes unavailable when running on cellular. Someone with cellular backup experience may have a better idea.

No i can't telnet the using the cellular IP. The node should be green since the cellular backup kicked in. That's my concern I'm trying to figure out.

I'm not sure what the problem is but it looks to me like a configuration issue on your router.

I'm guessing whilst you are running on the cellular link, users at the remote site could still ping their gateway 10.49.147.1 but you pinging it from the other end doesn't work so something on the router is blocking ICMP.

Hopefully someone else can look over your config and offer some advice.

Only thing I could see was this "ip nat inside source list xxx interface Cellular0/0/0 overload". Is it supposed to have xxx as the source list number?
