Module: DOCS-QOS3-MIB
OID (symbolic): DOCS-QOS3-MIB::docsQosParamSetTosOrMask
OID (numeric): 1.3.6.1.4.1.4491.2.1.21.1.2.1.21
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description:
This attribute specifies the OR mask for the IPv4 TOS value or IPv6 Traffic Class value. See the description of TosAndMask for further details. The IP TOS octet, as originally defined in RFC 791 has been superseded by the 6-bit Differentiated Services Field (DSField, RFC 3260) and the 2-bit Explicit Congestion Notification Field (ECN field, RFC 3168). The IPv6 Traffic Class octet RFC 2460 is consistent with that new definition. Network operators SHOULD avoid specifying values of TosAndMask and TosORMask that would result in the modification of the ECN bits.
What is docsQosParamSetTosOrMask?
This object specifies a bitmask that is logically OR'd with IPv4 Type-of-Service (ToS) or IPv6 Traffic Class values in QoS parameter sets to mark outgoing packets. The ToS/Traffic Class field can indicate quality-of-service requirements and is now more commonly understood via the Differentiated Services Field (DSField) standard. An operator configures this mask to ensure outgoing packets are marked with the appropriate service class or priority.
