Description: Specifies a TCP port mask for the source port if swCpuAclIpUseProtoType is TCP. Specifies a UDP port mask for the source port if swCpuAclIpUseProtoType is UDP.
What is swCpuAclIpTCPorUDPSrcPortMask?
This OID stores a 2-byte bitmask (0-65535 range) that defines which bits of the source TCP or UDP port number the switch examines, allowing wildcard port matching. Network engineers use this to match ranges of source ports like ephemeral client ports without listing each port individually. For example, a mask of 0xF000 applied to source port 49152 matches any source port in the range 49152-49167, useful for matching client port ranges.
