Hi, I have several devices with two network ports, one of which is a standby link that only comes up if the primary link goes down.
Both interfaces are always connected to switch ports. The primary connection goes to one switch, and the backup connection goes to another switch. If the first switch fails or is taken down for maintenance, the device fails over to the backup connection. It works just fine. The problem is how it looks in InterMapper. The switch that has the backup connections is always in the alarm state, although this is perfectly normal. In fact, if any of these interfaces should come up, it would actually signal an error condition! (It would mean that something has failed on the primary connection.) As Bizarro would say, "Me am thinking that alarms is good!" It would be nice if there was a way to reverse the normal meaning of "alarm" on these interfaces. Offhand I can't come up with an elegant way to do this with InterMapper's current design. Custom probes don't have the flexibility to replace an existing SNMP router probe and reverse the alarm state for a subset of the interfaces. (Or do they?) Does anyone have any suggestions?
