eltIfDot1qCustomEgressEtherType
Module: ELTEX-MES-IF-EXTENSION-MIB
OID (symbolic): ELTEX-MES-IF-EXTENSION-MIB::eltIfDot1qCustomEgressEtherType
OID (numeric): 1.3.6.1.4.1.35265.1.23.1.276.1.3.1.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The Dot1qEtherType allow administrator to select a non-standard (other than 0x8100) 2-byte ethertype for the interface to interoperate with third party vendor's system that do not use the standard 0x8100 ethertype to identify 802.1q-tagged frames.
The current administrative value of the 802.1q ethertype for the interface. The administrative 802.1q ethertype value may differ from the operational 802.1q ethertype value. On some platforms, 802.1q ethertype may be assigned per group rather than per port. If multiple ports belong to a port group, the 802.1q ethertype assigned to any of the ports in such group will apply to all ports in the same group.
To configure non-standard dot1q egress ethertype is only recommended when the Eltex device is connected to any third party vendor device.
What is eltIfDot1qCustomEgressEtherType?
This read-write Integer32 (0-65535), indexed by ifIndex, sets a non-standard 2-byte EtherType value the interface uses instead of the standard 0x8100 to mark outgoing 802.1q-tagged frames, for interoperating with third-party equipment that expects a different tag EtherType. Admins configure this only when connecting an Eltex switch to a third-party device that does not recognize 0x8100 as the VLAN tag identifier on egress traffic. For example, setting eltIfDot1qCustomEgressEtherType to 37120 (0x9100) on an uplink port matches a neighboring vendor's non-standard Q-in-Q EtherType expectation.
