ieee8021FramePreemptionActive

Module: IEEE8021-Preemption-MIB

OID (symbolic): IEEE8021-Preemption-MIB::ieee8021FramePreemptionActive

OID (numeric): 1.3.111.2.802.1.1.29.1.1.2.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The value is active (2) when preemption is operationally active for the Port, and idle (1) otherwise.

What is ieee8021FramePreemptionActive?

This read-only INTEGER shows whether frame preemption is operationally active(2) or idle(1) on the port right now. Admins poll it to confirm that preemption is actually engaged after enabling it via ieee8021FramePreemptionAdminStatus, since administrative configuration doesn't guarantee it's operationally active on the link. For example, seeing idle(1) after configuring preemptible traffic classes could indicate the far-end device doesn't support preemption, so it never activated.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.29.1.1.2.1.3
snmpwalk -v2c -c public <target> IEEE8021-Preemption-MIB::ieee8021FramePreemptionActive

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.29.1.1.2.1.3.1
