hcxRxFreqHop

Module: COM21-HCXRX-MIB

OID (symbolic): COM21-HCXRX-MIB::hcxRxFreqHop

OID (numeric): 1.3.6.1.4.1.1141.4.82

Node type: NOTIFICATION-TYPE

Description: This trap is generated when an RX port frequency is hopped due to errors. The hcxUpstrmActiveFreq varbind indicates the new frequency. Severity is WARNING.

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> '' COM21-HCXRX-MIB::hcxRxFreqHop
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1141.4.82

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]:53154->[192.168.30.10]:162]:
