Module: CIENA-CES-DATAPLANE-MIB
OID (symbolic): CIENA-CES-DATAPLANE-MIB::cienaCesDpTsCosMapFcosL2Dei
OID (numeric): 1.3.6.1.4.1.1271.2.1.7.1.3.2.1.1.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This object specifies the L2-Dei <0..1> mapping for a given RCoS
and RCOLOR value.
Octet 1: l2-dei for RCoS 0 with RCOLOR of Green
Octet 2: l2-dei for RCoS 0 with RCOLOR of Yellow
Octet 3: l2-dei for RCoS 1 with RCOLOR of Green
Octet 4: l2-dei for RCoS 1 with RCOLOR of Yellow
...
Octet 126: l2-dei for RCoS 63 with RCOLOR of Green
Octet 127: l2-dei for RCoS 63 with RCOLOR of Yellow
What is cienaCesDpTsCosMapFcosL2Dei?
This OCTET STRING decides whether egressing frames get the 802.1ad DEI, or drop-eligible, bit set, based on their internal RCoS and color. It lets the carrier signal downstream equipment that a given frame is excess traffic and safe to drop first under congestion, propagating the internal color decision back into the wire format the customer or next hop sees. Octet 93, corresponding to RCoS 46 with Yellow, might set DEI equal to 1 to flag that frame as discard-eligible on egress.
