Programmable Registers
29.9.35 ENET SWI Port Snooping function. Eight independent entries
TCP/UDP Port number Snooping function configuration.
Note: it is possible to set both the compare source/dest bits. The result is OR'ed, meaning
if any of the fields match the compare value, the frame is processed as defined by the mode
bits.

The 16-bit port number to compare within the TCP or UDP header of a frame.
Reserved bits. Write as 0.
When set, the TCP or UDP source port number field within the frame is compared with the compare value
provided in 31:16.
When set, the TCP or UDP destination port number field within the frame is compared with the compare
value provided in 31:16.
Defines the forwarding that should occur, when an IP frame is received and the protocol field matches the
protocol value (see bits 15:8).
Bits 2:1:
00: forward frame to designated management port only 01: copy to management port and forward normally
10: discard
Note: the management port is defined in register MGMT_CONFIG.
