dot3OamCriticalEventEnable

Module: DOT3-OAM-MIB

OID (symbolic): DOT3-OAM-MIB::dot3OamCriticalEventEnable

OID (numeric): 1.3.6.1.2.1.158.1.5.1.16

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: If true, the local OAM entity should attempt to indicate a critical event via the OAMPDU flags to its peer OAM entity when a critical event occurs. The exact definition of a critical event is implementation dependent. If the system does not support critical event capability, setting this object has no effect, and reading the object should always result in 'false'.

By default, this object should have the value true for Ethernet-like interfaces that support OAM. If the OAM layer does not support Event Notifications (as indicated via the dot3OamFunctionsSupported attribute), this value is ignored.

What is dot3OamCriticalEventEnable?

This read-write boolean, true by default where supported, controls whether the local OAM entity signals a 'critical event' flag to its peer when an implementation-defined severe fault occurs; unsupported hardware always reads back false. An admin would disable this only if the vendor's critical-event definition proves too noisy for their environment.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.158.1.5.1.16
snmpwalk -v2c -c public <target> DOT3-OAM-MIB::dot3OamCriticalEventEnable

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.158.1.5.1.16.1
snmpget -v2c -c public <target> DOT3-OAM-MIB::dot3OamCriticalEventEnable.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.158.1.5.1.16.1 s <value>
