cienaCesServiceDelimiterTPID
Module: CIENA-CES-MPLS-MIB
OID (symbolic): CIENA-CES-MPLS-MIB::cienaCesServiceDelimiterTPID
OID (numeric): 1.3.6.1.4.1.1271.2.1.18.1.4.1.1.39
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This represents the service delimiter TPID. This object is valid only for 39XX and 51XX platforms
What is cienaCesServiceDelimiterTPID?
This is the Tag Protocol Identifier (TPID) value expected on the service delimiter tag for this service -- distinguishing, for example, standard 802.1Q (0x8100) from 802.1ad Q-in-Q (0x88a8) tagged frames -- again applicable only on 39XX/51XX platforms. A mismatch between this configured TPID and what the customer's equipment actually sends is a classic cause of a service failing to classify incoming frames correctly even when the VLAN ID itself matches. If a customer's Q-in-Q tagged traffic isn't being recognized, checking whether this TPID matches their actual outer tag's EtherType is a direct diagnostic step.
