Ethernet/IP Functionality
General Bridging Function
–
Support IPv4 packet
– Support IEEE802.1d Ethernet bridge function between
trunk Ether port and ATM VCs
– Support Rapid Spanning Tree Protocol (RSTP) for the
trunk interfaces per IEEE 802.1w
– 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 up to a
maximum of 128 MAC entries per line port
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
different 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
encapsulation mode
– Support up to 256 multicast groups and 256 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
