SNMP Monitoring

I am having problems locating the correct MIBs to monitor using SNMP. I would like to monitor the counters displayed on the Radio interface's detailed status page when using the web browser.

I have found the CISCO-DOT11-ASSOCIATION-MIB stats, but that seems to count only workstations that are active. I would like to monitor all the stats and keep the running totals.

I looked in the 1.3.6.1.4.1.522 (Aironet) MIB but it seems to not be supported in the IOS only VXWorks.

Any insight would be most helpful also if there are any CLI commands I could use to collect the data I could create a expect script and parse the data also.

Thanks in advance.

Re: SNMP Monitoring

Are you running the APs in autonomous mode or lwapp mode? Also with model & sw version?

If you are using lwapp mode, you may have to glean the info from the controllers.

There are several good sources for doing so

Re: SNMP Monitoring

Hello,

Maybe these can help you:

snmputil walk 192.168.0.100 public .1.3.6.1.4.1.9.9.273.1.2.1.1.16 ' IP-addresses of the clients (as HEXes)

snmputil walk 192.168.0.100 public .1.3.6.1.4.1.9.9.273.1.2.1.1.13 ' MAC-addresses of the clients (as HEXes)

snmputil walk 192.168.0.100 public .1.3.6.1.4.1.9.9.273.1.3.1.1.3 ' Signal Strength (dBm)

snmputil walk 192.168.0.100 public .1.3.6.1.4.1.9.9.273.1.3.1.1.2 ' how many seconds the client has been connected

for example:

C:\>snmputil walk 192.168.0.100 public .1.3.6.1.4.1.9.9.273.1.3.1.1.3

Variable = .iso.org.dod.internet.private.enterprises.9.9.273.1.3.1.1.3.1.4.86.79

.73.80.0.27.212.84.66.85

Value = Integer32 -55

-55 would be the correct result for desibels

The snmputil.exe can be downloaded for example here: http://www.wtcs.org/snmp4tpc/FILES/Tools/SNMPUTIL/SNMPUTIL.zip

"192.168.0.100" would be the IP-address of the access point and "public" is the SNMP-communicty name

The IP-addresses and MAC-addresses come HEX-coded, so you must implement a simple HEX->ASCII conversion before you can really use them...
