Description: This object indicates the status of filtered addresses of UDP.
other (1) - Neither source port nor destination port are masked. dst-addr (2) - Packets will be filtered if this destination port is identified in received frames. src-addr (3) - Packets will be filtered if this source port is identified in received frames. dst-src-addr (4) - Packets will be filtered if this destination or source port is identified in received frames.
What is swCpuAclIpUdpOption?
This OID controls whether the ACL matches on UDP source ports, destination ports, both, or neither when filtering UDP-based protocols (enumeration: other, src-addr, dst-addr, or dst-src-addr). Network engineers use this to block or allow specific UDP services like DNS (port 53), DHCP (port 67/68), or NTP (port 123). For instance, setting this to dst-addr and matching destination port 53 lets you restrict DNS queries to only authorized servers.
