SNMP Monitoring

Unanswered Question
Oct 16th, 2007

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.

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...
