    primary and backup link stuff

    solidrock

      Guys,

       

      Question, is there a way if primary link (green) goes down (to red), node must still reflects as up when backup link kicked in (cellular)?

       

      My scenario was even if the cellular backup kicked in, the node still reflects as down (red).

       

      Thanks guys,

          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.
