4.2. Technical Specifications
4.2.1. Software Specification
Supports 802.1D bridge self-learning, storing up to 8K+ 256unicast or
multicast addresses
Supports automatic age-out period between 1 to 1,000,000 seconds
Broadcast storm filtering based on ingress port bandwidth
HOL blocking prevention
Deadlock relief
9K+ jumbo packets supported on per port and per VLAN basis
Supports layer 2 source filtering
Supports 802.1D Spanning Tree Algorithm and Protocol, and 802.1w Rapid
Reconfiguration
Flexible per-port VLAN classification option supports port-based VLAN
domain and 802.1Q VLAN domain simultaneously
Supports 802.1X Port-based Network Access Control
Supports 802.3ad Aggregation of Multiple Link Segments
Statistical load-balancing algorithm may be configured to be function of
source and destination MAC addresses, ingress port ID, source and
destination IP addresses, and TCP/UDP source and destination ports
Supports BPDU, LACP, EAPOL suppression based on per port
configuration
Supports 64 VLAN-dependent Spanning Trees
Supports IP multicast and snooping of IGMP and IP multicast routing
protocol PDU Including IGMP, CBT, OSPF, and PIM v2
IP multicast packets may be forwarded within single VLAN or across
multiple VLANs. Cross-VLAN mode allows each egress port to have its own
tag rule and VID for IP multicast packets
Supports Port mirroring
Supports 802.1p Traffic Priority
ToS-to-802.1p priority mapping
Supports 802.1p remarking:
The prioritization result can be made available to other switches in the
network by replacing priority field in VLAN tag
Four priority egress queues per port
QoS Scheduling algorithms: strict priority or weighted round robin
Four RMON groups (1,2,3,9)
Supports MIB of RFC1213, 1573, 1757, 1643, 2233
MAC address table synchronization assistance
Asymmetric VLAN membership for better network security:
Distinguish ingress VLAN member and egress VLAN member
Prevents a station to sneak in VLAN set up for common servers, e.g. IPTV
services
Improved VLAN ingress rules may specify:
Filtering untagged packets or VLAN tagged packets
Filtering packets received on non-ingress VLAN member ports
Supports insertion of 2nd tag with programmable TPID to VLAN-tagged
packets
Port-based ingress rate policing and egress rate pacing
