EtherLoop CO and CPE MAC Filter Tables
The EtherLoop MAC Filter Table provides the ability to manage the MAC
Filters for each modem. MAC Filtering is a means whereby communications
between modems may be prevented based on MAC addresses. This privacy
feature prevents traffic from other clients on the CO LAN from appearing at
the CPE modem.
Thus, a particular client cannot see traffic destined for other clients. In
addition, only registered hosts connected to the CPE modem can make use of
the connection. If no MAC addresses appear in the MAC Filter table for a
particular modem, it will pass all Ethernet traffic. If any MAC addresses
appear in the MAC Filter table for a particular modem, the modem will only
accept Ethernet packets for those addresses.
Figure A-4 shows an example screen shot for the EtherLoop Modem CO MAC
Filter and CPE MAC Filter tables. Table A-7 on page A-12 details the MIB
variables supported by these tables.
