chipPortDown

Module: CHIPCOM-MIB

OID (symbolic): CHIPCOM-MIB::chipPortDown

OID (numeric): 1.3.6.1.4.1.49.0.11

Node type: NOTIFICATION-TYPE

Description: A chipPortDown trap indicates that a port's status has changed to an error condition. Multiple chipPortDown traps may be sent if the port's status changes from one error to another.

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> '' CHIPCOM-MIB::chipPortDown
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.49.0.11

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]:51960->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (322307832) 37 days, 7:17:58.32
