Wireless Access

Hello,

I am trying to Monitor our Aruba wireless network with Nagios and am having a problem with the data the Aruba MIBs are returning...

Specicially, when I snmp walk a controller using the Aruba MIBs to find a specific AP, most of the info returned looks like:

WLSX-SWITCH-MIB::staUserName.'..{O..'.'...}`p' = STRING:

Instead of a human readable name, it returns with that odd string ('..{O..'.'...}`p')

Here is the same line when just using the standard SNMPv2

SNMPv2-SMI::enterprises.14823.2.2.1.1.2.2.1.6.0.18.123.79.196.169.0.11.134.125.96.112 = ""

It also looks like using the SNMPv2-SMI MIB, most of the same data is returned, so at this point it is easer to not use the Aruba MIBs but not ideal.  Has anyone else had this issue or not what may be causing it?

Cheers

add -O0X  (dash OH-zero-X)  to the snmpwalk command, i.e.

root@kali:/home/aruba/mibs/6.3.1.2# snmpwalk -v2c -c public -mALL -M. -O0X  c7030 .1.3.6.1.4.1.14823.2.2.1.5.2.1.7.1.9

WLSX-WLAN-MIB::wlanAPBssidUpTime[STRING: 00:24:6c:ca:24:78][1][STRING: 00:24:6c:22:47:88] = Timeticks: (1448700) 4:01:27.00

Perfect, thank you!

I have one more question, I am haivng a problem using snmpget to poll a specific AP.

As an exapmle, I would like to get the SNR of an AP...  When I ran snmpwalk, the first AP in the list looked like this:

WLSX-SWITCH-MIB::staSignalToNoiseRatio[STRING: 00:12:7b:4f:c4:a9][STRING: 00:0b:86:7d:60:70] = INTEGER: 12

I cannot use the above output for snmpget becuase of the formatting of "[STRING: 00:12:7b:4f:c4:a9][STRING: 00:0b:86:7d:60:70]". 

Can someone help me with with the correct snmpget command for that AP?

change it back to dotted format using -On flag instead of -O0X

root@bt:/home/aruba/mibs/6.4.2.x# snmpwalk -v2c -c public -M. -mALL -O0X 192.168.1.254 staSignalToNoiseRatio
WLSX-SWITCH-MIB::staSignalToNoiseRatio[STRING: 24:77:03:1f:54:90][STRING: ac:a3:1e:b7:df:30] = INTEGER: 55

root@bt:/home/aruba/mibs/6.4.2.x#

also can use -O0X in the snmpget to make it readable again:

root@bt:/home/aruba/mibs/6.4.2.x# snmpget -v2c -c public -O0X -M. -mALL 192.168.1.254 .1.3.6.1.4.1.14823.2.2.1.1.2.2.1.7.36.119.3.31.84.144.172.163.30.183.223.48

WLSX-SWITCH-MIB::staSignalToNoiseRatio[STRING: 24:77:03:1f:54:90][STRING: ac:a3:1e:b7:df:30] = INTEGER: 53
root@bt:/home/aruba/mibs/6.4.2.x#
