FEATURE

DESCRIPTION

VLAN

A VLAN (Virtual Local Area Network) allows a physical network to be

 

partitioned into multiple logical networks. Devices on a logical network

 

belong to one group. A device can belong to more than one group. With

 

VLAN, a device cannot directly talk to or hear from devices that are not

 

in the same group(s); the traffic must first go through a router.

 

 

MAC Address Filter

Filter traffic based on the source and/or destination MAC address and

 

VLAN group (ID).

 

 

DHCP (Dynamic Host

Use this feature to have the relay DHCP requests to DHCP servers on

Configuration Protocol)

your network.

 

 

IGMP Snooping

The Switch supports IGMP snooping enabling group multicast traffic to

 

be only forwarded to ports that are members of that group; thus allowing

 

you to significantly reduce multicast traffic passing through your Switch.

 

 

Differentiated Services

With DiffServ, the Switch marks packets so that they receive specific

(DiffServ)

per-hop treatment at DiffServ-compliant network devices along the route

 

based on the application types and traffic flow.

 

 

Queuing

Queuing is used to help solve performance degradation when there is

 

network congestion. Three scheduling services are supported: Strict

 

Priority Queuing (SPQ) and Weighted Round Robin (WRR). This allows

 

the Switch to maintain separate queues for packets from each individual

 

source or flow and prevent a source from monopolizing the bandwidth.

 

 

Port Mirroring

Port mirroring allows you to copy traffic going from one or all ports to

 

another or all ports in order that you can examine the traffic from the

 

mirror port (the port you copy the traffic to) without interference.

 

 

Static Route

Static routes tell the Switch how to forward IP traffic when you configure

 

the TCP/IP parameters manually.

 

 

Multicast VLAN Registration

Multicast VLAN Registration (MVR) is designed for applications (such as

(MVR)

Media-on-Demand (MoD)) using multicast traffic across a network. MVR

 

allows one single multicast VLAN to be shared among different

 

subscriber VLANs on the network.

 

This improves bandwidth utilization by reducing multicast traffic in the

 

subscriber VLANs and simplifies multicast group management.

 

 

STP (Spanning Tree

(R)STP detects and breaks network loops and provides backup links

Protocol) / RSTP (Rapid

between switches, bridges or routers. It allows a Switch to interact with

STP) / MSTP (Multiple STP)

other (R)STP-compliant switches in your network to ensure that only one

 

path exists between any two stations on the network. The Switch also

 

allows you to set up multiple STP configurations (or trees). Ports can

 

then be assigned to the trees.

 

 

Loop Guard

Use the loop guard feature to protect against network loops on the edge

 

of your network.
