Table 1-2: Key Features (Continued)
Feature Description
Virtual LANs Up to 4K using IEEE 802.1Q, port-based, and private VLANs
Traffic Prioritization Queue mode and CoS configured by Ethernet type, VLAN ID,
TCP/ UDP port, DSCP, ToS bit, VLAN tag priority, or port
Qualify of Service Supports Differentiated Services (DiffServ), and DSCP
remarking
Multicast Filtering Supports IGMP snooping and Proxy
DESCRIPTION OFFIRMWARE FEATURES
The switch provides a wide range of advanced performance and
Security enhancing features. Flow control eliminates the loss of packets
due to bottlenecks caused by port saturation. Storm suppression
prevents broadcast, multicast, and unknown unicast traffic storms from
engulfing the network. Untagged (port-based) and tagged VLANs, plus
support for automatic GVRP VLAN registration provide traffic security
and efficient use of network bandwidth. QoS priority queueing ensures
the minimum delay for moving real-time multimedia data across the
network. While IGMP Snooping function provides support for real-time
network applications.
Others the switch also supports TACACS+ and RADIUS authentication
for management security requirement and SSL and SSH for encryption
for all HTTP traffic and all transmitted data for secure, remote
command-line interface (CLI) access over IP networks
Some of the management features are briefly described below.
The Syslog is a standard for logging program messages . It allows
separation of the software that generates messages from the
system that stores them and the software that reports and analyzes
them. It is supported by a wide variety of devices and receivers
across multiple platforms.
Support Quality of Service by the IEEE 802.1P standard. There are
two priority queue and packet transmission schedule. multiple
platforms.
SNMP agent and RMON MIB. In the device, SNMP agent is a client software
which is operating over SNMP protocol used to receive the command from
SNMP manager (server site) and echo the corresponded data, i.e. MIB object.
Besides, SNMP agent will actively issue TRAP information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of the
SNMP MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON MIB
(RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643), Ethernet
MIB (RFC 1643) and so on.multiple platforms.
