cnt2XIfLinkUpDownTrapEnable
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfLinkUpDownTrapEnable
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.13
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Indicates whether linkUp/linkDown traps should be generated for this interface. By default, this object should have the value enabled(1) for interfaces which do not operate on 'top' of any other interface (as defined in the ifStackTable), and disabled(2) otherwise.
What is cnt2XIfLinkUpDownTrapEnable?
This read-write enumerated INTEGER controls whether SNMP linkUp and linkDown traps are generated for this specific interface, defaulting to enabled on top-level interfaces and disabled on interfaces stacked beneath others. An administrator disables it on sub-interfaces to avoid redundant trap floods when the underlying physical port already reports the same state change. For example, setting cnt2XIfLinkUpDownTrapEnable to disabled(2) on a logical sub-interface stops a duplicate trap from firing every time the physical port beneath it flaps.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.2.1.2.3.1.13 snmpwalk -v2c -c public <target> CNT21-MIB::cnt2XIfLinkUpDownTrapEnable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.333.2.1.2.3.1.13.1 snmpget -v2c -c public <target> CNT21-MIB::cnt2XIfLinkUpDownTrapEnable.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.333.2.1.2.3.1.13.1 i <value>
