a3ComVlanEncapsIfType
Module: GENERIC-3COM-VLAN-MIB-1-0-1
OID (symbolic): GENERIC-3COM-VLAN-MIB-1-0-1::a3ComVlanEncapsIfType
OID (numeric): 1.3.6.1.4.1.43.10.1.14.4.1.1.2
Node type: OBJECT-TYPE
Type: A3ComVlanEncapsType
Access: read-write
Description: The encapsulation algorithm used when encapsulating packets transmitted, or de-encapsulating packets received through this interface.
What is a3ComVlanEncapsIfType?
This value selects which tagging scheme the encapsulation interface uses — the 3Com-proprietary PDD VLT tagging, standard 802.1q tagging, or the pre-standard 802.1q ONcore variant. The chosen algorithm determines exactly how the switch reads and writes the VLAN tag on frames passing through this interface, which must match what the peer device on the segment expects. An admin connecting to a standards-based upstream switch would set a3ComVlanEncapsIfType to vlanEncaps8021q(2) rather than the legacy 3Com-proprietary PDD scheme.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.10.1.14.4.1.1.2 snmpwalk -v2c -c public <target> GENERIC-3COM-VLAN-MIB-1-0-1::a3ComVlanEncapsIfType
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.10.1.14.4.1.1.2.1 snmpget -v2c -c public <target> GENERIC-3COM-VLAN-MIB-1-0-1::a3ComVlanEncapsIfType.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.10.1.14.4.1.1.2.1 s <value>
