Hi, I was wondering if there has been a collective effort to document the meaning of the NAS-Port by the various Network Vendors? We are working on PacketFence here (an open source NAC) and we translate the NAS-Port to the ifIndex so we can request a dot1x reauthentication to the ifIndex if we want to (ie: IDS event). We've done the translation by ourselves since vendor documentation is often lacking and I was thinking there must exist such a resource. Does anyone here know? I know we could use CoA with the original NAS-Port but it's less supported than the SNMP PAE Reauthenticate MIBs.
