rdnCmtsUpstreamIfLinkDownTrap
Module: RDN-CMTS-MIB
OID (symbolic): RDN-CMTS-MIB::rdnCmtsUpstreamIfLinkDownTrap
OID (numeric): 1.3.6.1.4.1.4981.2.4.0.4
Node type: NOTIFICATION-TYPE
Description: This trap provides more information than the standard linkDown trap, by adding varbinds to include the spectrum group name, ifDescr, and ifType.
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> '' RDN-CMTS-MIB::rdnCmtsUpstreamIfLinkDownTrap snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.4981.2.4.0.4
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]:52318->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (240493662) 27 days, 20:02:16.62 SNMPv2-MIB::snmpTrapOID.0 = OID: RDN-CMTS-MIB::rdnCmtsUpstreamIfLinkDownTrap
