docsIetfQosPktClassIpTosLow
Module: DOCS-IETF-QOS-MIB
OID (symbolic): DOCS-IETF-QOS-MIB::docsIetfQosPktClassIpTosLow
OID (numeric): 1.3.6.1.2.1.127.1.1.1.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The low value of a range of TOS byte values. If the referenced parameter is not present in a classifier, this object reports the value of 0.
The IP TOS octet, as originally defined in RFC 791, has been superseded by the 6-bit Differentiated Services Field (DSField, RFC 3260) and the 2-bit Explicit Congestion Notification Field (ECN field, RFC 3168). This object is defined as an 8-bit octet as per the DOCSIS Specification for packet classification.
What is docsIetfQosPktClassIpTosLow?
The low end of an IP TOS byte range this classifier matches against, reported as 0 if no TOS range was configured. Combined with docsIetfQosPktClassIpTosHigh and the AND mask, it lets you classify traffic by DSCP/TOS marking, e.g. to route already-marked VoIP packets into a low-latency service flow.
