QoS with Four Priority Queues
Extensive QoS features make the solution ideal for real-time
applications like VoIP and IPTV. The 4 priority queues together with the
Weighted Round Robin and Strict Priority scheduling techniques
facilitate efficient co-existence of real-time traffic with data traffic
allowing them each to meet their QoS needs. Individual users or
applications can be prioritized above others using various Class of
Service options by port, layer 2 priority (802.1p), Layer 3 priority (TOS
or DSCP), IPv6 Traffic Class or TCP/UDP service number.
Enhancing Security, Traffic Flow Classification and Prioritize by
Powerful ACL rule
Access control lists (ACLs) provide an effective means for limiting the
types of traffic permitted on a network; thus enhancing security by
preventing unauthorized activity. ACLs are, as the name implies, a
series of lists that are processed for every frame received by the switch.
Each list consists of a set of rules. Each rule is defined by a set of
criteria. It is the flexibility that the switch allows in configuring these
lists, rules and criteria that gives the ACLs their power.
Port Mirroring
Port mirroring copies traffic from a specific port to a target port. This
mechanism helps track network errors or abnormal packet transmission
without interrupting the flow of data.
VLAN for Performance & Security
The VLAN feature in the switch offers the benefits of both security and
performance. VLAN is used to isolate traffic between different users and
thus provides better security. Limiting the broadcast traffic to within the
same VLAN broadcast domain also enhances performance.
Port Trunk for Bandwidth Aggregation
The Gigabit ports can be combined together to create a multi-link load-
sharing trunk. Up to 12 Gigabit ports can be set up per trunk. The switch
supports up to 8 trunking groups. Port trunks are useful for switch-to-
switch cascading, providing very high full-duplex speeds.
Trap Event for Exception Management
We use SNMP Trap mechanism to inform supervisor to know the instant
abnormal status of the switch.
4 Dual Media Ports for Flexible Fiber Connection
The dual media ports are provided for flexible fiber connection. You can
select to install optional transceiver modules in these slots for short,
medium or long distance fiber backbone attachment. Use of the SFP will
disable their corresponding built-in 10/100/1000Base-T connections.
Build-in Web-base Management
Instead of using CLI interface, we provide a more convenient GUI for
user. We just need to configure switch via Web Browser. It is more
quickly for user to familiar the method to control switch on the basis of
this design.
