MANAGEMENT SOFTWARE SPECIFICATIONS
System Configuration
Auto-negotiation supports on 10/100Base-TX ports; web browser or console interface can set transmission speed (10/100Mbps) and operation mode (Full/Half Duplex) on each port; enable/disable any port, set VLAN group(s), set trunk connection.

Management Agent
SNMP supports; MIB II, Bridge MIB, RMON MIB
Spanning Tree Algorithm
IEEE 802.1D
VLAN Function
Port-based / 802.1Q Tagged-based, allowed up to 256 active VLANs in one switch

Trunk Function
Ports trunk connections allowed

IGMP
IP Multicast filtering by passively snooping on the IGMP Query
Bandwidth Control
Supports by-port Egress/Ingress rate control

Quality of Service (QoS)
Referred as Class of Service (CoS) by the IEEE 802.1P standard
— Four queues per port
— Packet transmission schedule using Weight Round Robin (WRR)
— User-defined weight
— Classification of packet priority can be based on either a VLAN tag on packet or user-defined

Port Security
Limited numbers of MAC addresses learned per port; static MAC addresses stay in the filtering table

Inter-networking Protocol
Bridging: 802.1D Spanning Tree
IP Multicast
— IGMP Snooping
— IP Multicast Packet Filtering
— Maximum of 256 active VLANs and IP Multicast sessions

Network Management
One (1) RS-232 port as local control console
Telnet remote control console
SNMP agent: MIB-2 (RFC1213), Bridge MIB (RFC1493), RMON MIB (RFC1757), Ethernet-like MIB (RFC1643)
