15.6.2.6 RMON Support
Using promiscuous mode, the eTSEC can automatically gather network statistics required for remote
network interface monitoring. The RMON MIB group 1, RMON MIB group 2, RMON MIB group 3,
RMON MIB group 9, RMON MIB2, and the IEEE 802.3 Ethernet MIB are supported. For RMON
statistics and their corresponding counters, see the memory map.
15.6.2.7 Frame Recognition
The Ethernet controller performs frame recognition using destination address (DA) recognition. A frame
can be rejected or accepted based on the outcome.
