docsIetfQosServiceClassTosOrMask
Module: DOCS-IETF-QOS-MIB
OID (symbolic): DOCS-IETF-QOS-MIB::docsIetfQosServiceClassTosOrMask
OID (numeric): 1.3.6.1.2.1.127.1.8.1.21
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Template for docsIetfQosParamSetTosOrMask. The IP TOS octet as originally defined in RFC 791 has been superseded by the 6-bit Differentiated Services Field (DSField, RFC 3260) and the 2-bit Explicit Congestion Notification Field (ECN field, RFC 3168). Network operators SHOULD avoid specifying values of docsIetfQosServiceClassTosAndMask and docsIetfQosServiceClassTosOrMask that would result in the modification of the ECN bits.
In particular, operators should not use values of docsIetfQosServiceClassTosAndMask that have either of the least-significant two bits set to 0. Similarly, operators should not use values of docsIetfQosServiceClassTosOrMask that have either of the least-significant two bits set to 1.
What is docsIetfQosServiceClassTosOrMask?
Part of a named Service Class template: the OR mask applied to the IP TOS byte for flows built from this class, mirroring docsIetfQosParamSetTosOrMask; operators are advised not to use values here that would alter the ECN bits.
