Cisco has the most granular dBm lookup table.

Hello,

It is possible to monitor with snmp, 1310 bridge wireless signal quality?

Thanks and regards

Try CISCO-DOT11-ASSOCIATION-MIB::cDot11ClientSigQuality

<http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.9.273.1.3.1.1.4>

This is indexed by ifIndex/SSID/MAC.

In case you don't have access to the MIB here are the OIDs to walk:

1.3.6.1.4.1.9.9.273.1.3.1.1.3 cDot11ClientSignalStrength

1.3.6.1.4.1.9.9.273.1.3.1.1.4 cDot11ClientSigQuality

Example using Net-SNMP:

cDot11ClientSignalStrength[1]["SSIDXXXXXXXXX"][0:11:92:XX:XX:XX] = -59 dBm

cDot11ClientSigQuality[1]["SSIDXXXXXXXXX"][0:11:92:XX:XX:XX] = Gauge32: 38 percentage

Thanks kka,

I'll try, It's important for us to monitor, because the the bad weather is important.
