When I do a snmpwalk I get the following result:
snmpwalk -v2c -On lan-controllers ip -c community system
.1.3.6.1.2.1.1.1.0 = STRING: Cisco Controller
.1.3.6.1.2.1.1.2.0 = OID: .1.3.6.1.4.1.14179.1.1.4.3
Without the -On option:
snmpwalk -v2c lan-controllers ip -c community system
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.14179.1.1.4.3
So it seems to me that NAV is the problem not the controller.

I did the same thing towards one of our controllers:
...
snmpwalk -v2c -On lan-controllers ip -c community system
.1.3.6.1.2.1.1.1.0 = STRING: Cisco Controller
.1.3.6.1.2.1.1.2.0 = OID: .1.3.6.1.4.1.14179.1.1.4.4
.1.3.6.1.2.1.1.3.0 = Timeticks: (386918800) 44 days, 18:46:28.00
.1.3.6.1.2.1.1.4.0 = STRING:
.1.3.6.1.2.1.1.5.0 = STRING: wlan_gsw_wism_1_2
.1.3.6.1.2.1.1.6.0 = STRING:
.1.3.6.1.2.1.1.7.0 = INTEGER: 2
...
snmpwalk -v2c -On lan-controllers ip -c community system
SNMPv2-MIB::sysDescr.0 = STRING: Cisco Controller
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.14179.1.1.4.4
SNMPv2-MIB::sysUpTime.0 = Timeticks: (386927900) 44 days, 18:47:59.00
SNMPv2-MIB::sysContact.0 = STRING:
SNMPv2-MIB::sysName.0 = STRING: wlan_gsw_wism_1_2
SNMPv2-MIB::sysLocation.0 = STRING:
SNMPv2-MIB::sysServices.0 = INTEGER: 2
What version of software are you running on your controllers?

Hi.
Has NAV any support for Cisco Wireless Lan Controller 440x ? Trying to add
my own device using editDb gives following output:
[...]
...
Snmp error 2 at 1 (.1.3.6.1.2.1.1.2.0, NULL: )
This is NAV's somewhat cryptic way of telling you that the remote SNMP agent
doesn't know the OID.  (The code was recently changed to give a more friendly
error message in this case, and it will be in place for NAV 3.3).
The OID in this case is sysObjectID.0; if your Cisco Wireless Lan Controller
440x reports a noSuchName error for this OID, then I'd say something is
seriously wrong with your controller.
NTNU reports that they have added a Cisco WLAN controller to their NAV with no
problems, so I'm not sure what causes your problem.
As to your question of "any support for" the Cisco WLAN Controller 440x, the
answer is yes.  I.e., it is an IP device, and can be status monitored by NAV.
 The box should support SNMP (although something about that seems broken in
your case), so you will be able to retrieve some basic SNMP data from it.  But
that is all.
When it comes to actually retrieving info about the slaves controlled by the
box, NAV has no idea.  We are working on better support for autonomous Cisco
WLAN AP's this year, in fact Andreas Knudsen from the University College of
?stfold is coming up here next week to work on this support.   Unfortunately,
we have no current plans of supporting the special case of a Cisco WLAN
Controller, as we currently haven't enough resources to work on it.  We are
aware, though, that they are growing more popular and should be supported, but
we have no idea yet how they can best be supported by NAV, and not sure how
the controller/slave concept maps into NAV's existing data model.  Whoever is
going to work out some support for this box, must have access to one and the
proper Cisco documentation for it.
