MANAGEMENT SUPPORT |
- System Configuration
Auto-negotiation supports on 10/10/1000Base-T ports, web browser or console interface can set transmission speed (10/100/1000Mbps) and operation mode (Full/Half duplex) on each ports, set VLAN group, 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, 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
Support by-port Egress/Ingress rate control
- Quality of Service (QoS)
Referred as Class of Service (CoS) by IEEE 802.1P standard.
— Four queues per port
— Packet transmission schedule using Weighted Round Robin (WRR)
— User-defined weight
