• 8K MAC entries
• 4Mbits packet buffer
Traffic Management and QoS
• IEEE 802.1p
• 8 egress queues per port for different
types of traffic
• WRR (Weighted Round Robin)
scheduling for different prioritization
of packets
• SPQ (Strict Priority Queuing) for
highest priority packets to get best
service
• IEEE 802.1Q tag-based and
port-based VLAN
• 256 static VLAN, up to 4K
dynamic VLAN
• Support GVRP, automatic VLAN
member registration
• Supports jumbo frame, up to 9K Bytes
• Supports IGMP snooping
• Congestion control on all ports
• Rate limiting(Ingress rate)
- Allow bandwidth to be shaped in
steps at 64Kbps
- Supports 14 scales for incremental
rate limiting incrementally
Link Aggregation
• IEEE 802.3ad compliant
• Support LACP, static and dynamic link
aggregation
• Up to 4 aggregation groups
• 8 ports per group randomly selected
Redundancy for Fault Backup
• IEEE802.1w Rapid Spanning Tree
Protocol (RSTP) provides rapid
convergence of spanning tree
independent of spanning-tree timer
User Security and Authentication
• MAC filtering per port secures access
to each port
• Specific MAC forwarding per port:
only specified MAC addresses can
access the network (port lock)
• 802.1x port-based security, prevent
unauthorized client access to the
network
• Private VLAN provides security and
isolation between ports on a switch,
ensures that users can not snoop on
each other’s traffic
Network Administration Security
• User name/password required for
web/telnet/local console
administrators
• Two level security by specific SNMP
read/write community
Network Management
• Supports ZyXEL iStacking
TM
, up to 24
switches can be managed by one IP
• Web-based management
• Telnet CLI
• SNMP v2c
• RS-232c Local console
• IP management: static IP or
DHCP client
• RMON four RMON groups 1, 2, 3, 9
(history, statistics, alarms, and events)
for enhanced traffic management,
monitoring, and analysis
• Port mirroring: supports
Source/Destination/Both port mirroring
