ACC-MIB::accDialOrigIpParm stores detailed filter parameters as an octet string that controls protocol matching and port-based filtering for dial origination rules. The parameter is encoded byte-by-byte: byte 0 specifies logical operations (None, NOT, Equals), bytes 1-2 contain the protocol number, byte 3 sets comparison operations for both/destination/source, and bytes 4-5 contain the TCP/UDP port number. A network engineer uses this to create sophisticated rules like 'dial out when port 80 (HTTP) traffic appears.' Example value: A value with protocol set to 6 (TCP) and port 443 would mean the filter matches HTTPS traffic specifically.
