Ethernet/IP Functionality
•
General Bridging Function
-
Support IPv4 packet
-
Support IEEE802.1d Ethernet bridge function between trunk Ether port and ATM VCs
-
Support static source MAC table provisioning, automatic source MAC learning and block duplicate ones
-
The system is able to maintain 4K entries in its own static MAC address table and to provision the sup-
ported number of MAC entries of a line port with a restriction of less than the maximum supported num-
ber, 128.
•
VLAN
-
Support IEEE 802.1q Port-based VLAN and Protocol-based VLAN
-
Support 512 non-stacked VLAN-ID simultaneously ranging from 1 to 4095
-
Support VLAN stacking and VLAN cross-connect
-
Support IP Spoofing prevention
-
Support MAC anti-Spoofing
-
Support port isolation functionality. When port isolation is enabled, no Layer-2 bridging between differ-
ent ports (or subscriber lines) is supported in a VLAN
-
Support static VLAN group and membership provisioning
•
Multicast
-
Support IP multicast forwarding and the multicast works well for RFC2684 bridged payload encapsula-
tion mode
-
Support up to 256 multicast groups and 512 copies simultaneously
-
Support profile-based Multicast Access Control (up to 48 profiles) and assign any profile to a subscriber
interface (the number of multicast channels within a profile is 256)
-
Support to limit maximum number of IGMP groups joined per bridge port
-
Support IGMP snooping/proxy per IGMP v1, v2, and v3
-
Support selection between IGMP proxy and IGMP snooping
•
ACL/Filtering
-
Support Layer-2 frame filtering based on source/destination MAC addresses and EtherType
-
Support Layer-3 filtering based on IP header including source/destination IP address, protocol ID, and
TCP/UDP destination port number
•
Relay Functionality
-
Support DHCP forward and DHCP relay agent option-82 functionality. The value within Circuit ID
and Remote ID sub-options is configurable.
-
Support PPPoE relay
