ieee8021BridgePortUseDEI

Module: IEEE8021-BRIDGE-MIB

OID (symbolic): IEEE8021-BRIDGE-MIB::ieee8021BridgePortUseDEI

OID (numeric): 1.3.111.2.802.1.1.2.1.3.1.1.4

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: If the Use_DEI is set to true(1) for the Port then the drop_eligible parameter is encoded in the DEI of transmitted frames, and the drop_eligible parameter shall be true(1) for a received frame if the DEI is set in the VLAN tag or the Priority Code Point Decoding Table indicates drop_eligible True for the received PCP value. If the Use_DEI parameter is false(2), the DEI shall be transmitted as zero and ignored on receipt. The default value of the Use_DEI parameter is false(2).

What is ieee8021BridgePortUseDEI?

Whether this port encodes and decodes drop-eligibility using the DEI bit of the VLAN tag; when false, the default, DEI is always transmitted as zero and ignored on receipt.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.2.1.3.1.1.4
snmpwalk -v2c -c public <target> IEEE8021-BRIDGE-MIB::ieee8021BridgePortUseDEI

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.2.1.3.1.1.4.1
snmpget -v2c -c public <target> IEEE8021-BRIDGE-MIB::ieee8021BridgePortUseDEI.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.111.2.802.1.1.2.1.3.1.1.4.1 s <value>
