We have a problem where we have some hundreds packetfronts, these are switches and routers made for broadband delivery and they do not come up as expected in NPM. In NPM they come up as Wireless APs and in network atlas the link between their interfaces do not come up. I think it can be said they are not supported yet. I know they use a protocol named PFDP instead of the standard LLDP and probably do not have a standard OID setup but I could be wrong on the last one. Becasue of all this I was wondering if there is a way to manually tell NPM how they work, where should I begin to read and look to fix something like this?
