how to disable snmp trap:snmp trap cefcPowerStatusChange

Answered Question

on our C6500 (IOS) switches, each time an IP phone connected or disconnected will result to a trap like this:


snmp trap cefcPowerStatusChange

Event details:

cefcFRUPowerAdminStatus = 3

cefcFRUPowerAdminStatus.3019 = 3

cefcFRUPowerOperStatus = 2

cefcFRUPowerOperStatus.3019 = 2

entPhysicalDescr = 10/100/1000BaseT

entPhysicalDescr.3019 = 10/100/1000BaseT

entPhysicalName = Gi2/8

entPhysicalName.3019 = Gi2/8

monitor = localhost

oid =

in the config, we have:

snmp-server enable traps snmp linkdown linkup coldstart warmstart

snmp-server enable traps chassis

snmp-server enable traps module

snmp-server enable traps bridge newroot topologychange

snmp-server enable traps stpx inconsistency root-inconsistency loop-inconsistency

snmp-server enable traps fru-ctrl

snmp-server enable traps entity

snmp-server enable traps vtp

snmp-server enable traps vlancreate

snmp-server enable traps vlandelete

snmp-server enable traps flash insertion removal

snmp-server enable traps c6kxbar intbus-crcexcd intbus-crcrcvrd

snmp-server enable traps envmon fan shutdown supply temperature status

snmp-server enable traps vlan-mac-limit

IS there anyway to disable trap for "power status change"?

Since it's from CISCO-ENTITY-FRU-CONTROL-MIB, it can probably be disabled by "no snmp-server enable traps fru-ctrl"

3019 is a dynmaically generated index number identifying the unique object.

The config you posted above is from IOS.

For CatOS: "clear snmp trap enable entityfru"

here is output from CatOS C6500

Traps Enabled: autoshutdown,callhomesmtp,chassis,entity,envfan,envpower,





Port Traps Enabled: 5/1-9,6/1-9

Module inlinepower traps enabled: 1-4,8

I don't see entityfru, just "entity"

do I need to clear anything?

What's the "show version" on it?

Apparently I missed the fact is an ENTITY-MIB trap, in which case you would want to "clear snmp trap entity" to stop it.

Erratum to one of the earlier posts: It should've been "clear snmp trap entityfru"--no "enable" when "clear".

Note it's "entity" in my first paragraph: You want to use "clear snmp trap entity" to stop the traps on your CatOS.
