dot1qTunnelEtherType
Module: COMTROL-ES8510-MIB
OID (symbolic): COMTROL-ES8510-MIB::dot1qTunnelEtherType
OID (numeric): 1.3.6.1.4.1.2882.2.1.1.5.2.5.1
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: ethertype/TPID
What is dot1qTunnelEtherType?
This read-write two-byte value sets the custom Tag Protocol Identifier (TPID or EtherType) used for double-tagged (QinQ) frames on this port, instead of the standard 802.1Q value of 0x8100. An admin changes this when implementing VLAN tunneling so customer VLAN tags can be distinguished from the provider's own outer tag. For example, setting this to 0x9100 instead of 0x8100 lets the switch tunnel a customer's inner VLAN tags transparently across a service-provider uplink using a distinct outer TPID that downstream equipment recognizes as the tunnel tag.
