docsMcastCmtsGrpCfgTosMask
Module: DOCS-MCAST-MIB
OID (symbolic): DOCS-MCAST-MIB::docsMcastCmtsGrpCfgTosMask
OID (numeric): 1.3.6.1.4.1.4491.2.1.18.1.1.1.10
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-create
Description: This attribute identifies the mask value bitwise ANDed with a TOS byte value to be defined in a packet classifier this GC instantiates in the GCR in order to limit the GCR-matched traffic to a particular set of DSCPs. This applies to the IPv4 TOS byte and the IPv6 Traffic Class byte. The IP TOS octet, as originally defined in RFC 791, has been superseded by the 6-bit Differentiated Services Field (DSField, RFC 3260) and the 2-bit Explicit Congestion Notification Field (ECN field, RFC 3168).
What is docsMcastCmtsGrpCfgTosMask?
Bitmask ANDed with the incoming TOS/DSCP byte before comparing it against the TosLow/TosHigh range, letting an admin match only the DSCP bits that matter (e.g. ignoring the ECN bits) rather than the whole byte.
