Problem: we want to query Cisco 5400's for simultaneous use, but for VoIP, there is no Nas-Port in the Access-Request, only Cisco-Nas-Port.
My understanding is that, to double check the Session DB's accuracy, snmpget will do a lookup based on NAS-Identifier, NAS-Port, and Username, and a few other things (see Nas.pm, isOnline()):
($name, $nas_id, $nas_port, $session_id, $client, $framed_ip_address)
For the Ciscos in particular, it appears to use:
($nas_id,
$client->{SNMPCommunity},
"$Radius::Nas::CiscoMIB.2.9.2.1.18.$nas_port")
and it's all looking under the MIB:
.iso.org.dod.internet.private.enterprises.9
(See also SessSQL.pm). Obviously, we can modify the SessionDatabase's AddQuery to insert the Cisco-NAS-Port rather than the Nas-Port. But how do we get snmpget to query that info in the Cisco MIB?
Thanks in advance!!
