docsQosPktClassIpSourceMask
Module: DOCS-QOS3-MIB
OID (symbolic): DOCS-QOS3-MIB::docsQosPktClassIpSourceMask
OID (numeric): 1.3.6.1.4.1.4491.2.1.21.1.1.1.9
Node type: OBJECT-TYPE
Type: InetAddress
Access: read-only
Description:
This attribute specifies which bits of a packet's IP Source Address are compared to match this rule. An IP packet matches the rule when the packet source address bitwise ANDed with the InetSourceMask value equals the docsIetfQosIpPktClassInetSourceAddr value. The address type of this attribute is specified by InetAddressType.
If the referenced parameter is not present in a classifier, this attribute reports the value of 'FFFFFFFF'H.
What is docsQosPktClassIpSourceMask?
This read-only attribute specifies a bitmask that determines which bits of an IP source address are compared when evaluating Quality of Service packet classifier rules in a DOCSIS system. Network engineers use this configuration to define how broadly or narrowly traffic is matched by source address (e.g., matching a full /32 address or an entire /24 subnet). Understanding this mask is essential for proper QoS policy application.
