| Description | IP TOS bits value, defined as all eight bits of the Service
Type octet in the IPv4 header. There are multiple, overlapping,
meanings of the TOS octet in use today:
Precedence (bits 7-5): IP Precedence, values 0-7
DSCP (bits 7-2): IP DiffServ Code Point, values 0-63
TOS (bits 7-0): IP Type of Service, by bits, values 0-255
Each of these definitions can be produced using the appropriate
agentDiffServAuxMfClfrTosMask mask value. These definitions are
mutually-exclusive, so only one is allowed for any given classifier
element. |
