gmplsSonetSdhBranch

Module: GMPLS-LABEL-MIB

OID (symbolic): GMPLS-LABEL-MIB::gmplsSonetSdhBranch

OID (numeric): 1.3.6.1.3.0.0.1.1.10

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-create

Description: The Branch Indicator (L) of a Sonet or SDH Generalized Label. 0 indicates that this field is non-significant. Only valid if mplsLabelType is set to other(1), gmplsLabelType is set to generalizedLabel(2), and gmplsLabelSubtype is set to sonetLabel(4) or SdhLabel(5).

What is gmplsSonetSdhBranch?

This value reports the Branch Indicator (L) field of a SONET or SDH Generalized Label, valid only when gmplsLabelSubtype is sonetLabel(4) or sdhLabel(5), with 0 meaning the field is not significant. An engineer uses it to identify which branch of the SONET/SDH multiplexing tree a given signal occupies when parsing a generalized label for a TDM circuit. For example, a nonzero Branch Indicator would distinguish one tributary branch from its siblings within the same higher-order signal.
