mscVrIpPgCosTreatmentTosMask
Module: Nortel-MsCarrier-MscPassport-IpCosMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-IpCosMIB::mscVrIpPgCosTreatmentTosMask
OID (numeric): 1.3.6.1.4.1.562.36.2.1.100.6.20.3.10.1.5
Node type: OBJECT-TYPE
Type: Hex
Access: read-write
Description: This attribute specifies the Type Of Service (TOS) bit mask with which the packets are examined and updated when this COS treatment is selected. The mask specifies which bits within the original TOS byte are to be examined or updated by the router.
When the setTosByte is set to yes, this attribute is used in conjunction with the tos attribute to determine how the TOS byte is updated using the following formula:
New TOS = ( Original TOS & ~tosMask ) | ( tos & tosMask )
For example:
Original TOS byte: hex 8A (10001010 in binary) tos attribute: hex 12 (00010010 in binary) tosMask attribute: hex 3F (00111111 in binary)
The changed TOS byte would be: hex 92 (10010010 in binary).
When the TosMap component is provisioned under this Policy, this attribute is used in conjunction with the tos attribute of the TosMap component when packets are examined for matching TOS bits.
By default, this attribute is set to the value of hex E0, i.e. bit 0, 1 and 2 of the TOS byte (the Precendence bits) are eligible to be examined and updated.
When either the setTosByte is set to yes, or when the TosMap component is provisioned, a zero tosMask is considered invalid,
What is mscVrIpPgCosTreatmentTosMask?
Bit mask (default hex E0, the Precedence bits) determining which bits of a packet's TOS byte are examined or rewritten by this CosTreatment, whether for TOS-byte rewriting or for matching against a TosMap component's values.
