ciscoLwappDot11ClientCoverageHolePreAlarmRev
Module: CISCO-LWAPP-RRM-MIB
OID (symbolic): CISCO-LWAPP-RRM-MIB::ciscoLwappDot11ClientCoverageHolePreAlarmRev
OID (numeric): 1.3.6.1.4.1.9.9.615.0.5
Node type: NOTIFICATION-TYPE
Description: The system generates this notification when the RRM coverage hole detection algorithm detects areas of radio coverage in a wireless LAN that are below the level needed for robust radio performance.
If clients on a access point are detected at threshold levels (RSSI, percentage of failed packets, and number of failed packets) specified in RRM configuration, the access point sends a 'coverage hole' alert to the controller.
This notification is generated in any of the following conditions
1)When the failed packet count is more than failed packet count threshold represented by clrRrmParametersVoicePktCountThreshold for voice and clrRrmParametersDataPktCountThreshold for data.
2)When the percentage of failed packet count is more than the failed packet count threshold represented by clrRrmParametersVoicePktPercentThreshold for voice and clrRrmParametersDataPktPercentThreshold for data.
3)When RSSI value is lower than the RSSI threshold represented by clrRrmParametersVoiceRssiThreshold for voice and clrRrmParametersDataRssiThreshold for data.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' CISCO-LWAPP-RRM-MIB::ciscoLwappDot11ClientCoverageHolePreAlarmRev snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.615.0.5
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:54191->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (500733871) 57 days, 22:55:38.71 SNMPv2-MIB::snmpTrapOID.0 = OID: CISCO-LWAPP-RRM-MIB::ciscoLwappDot11ClientCoverageHolePreAlarmRev
