FEATURE

DESCRIPTION

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 Switch assign IP addresses, an IP

Configuration Protocol)

default gateway and DNS servers to computers on 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

(DiffServ)

specific per-hop treatment at DiffServ-compliant network

 

devices along the route based on the application types and

 

traffic flow.

 

 

Classifier and Policy

You can create a policy to define actions to be performed on a

 

traffic flow grouped by a classifier according to specific criteria

 

such as the IP address, port number or protocol type, etc.

 

 

Queuing

Queuing is used to help solve performance degradation when

 

there is network congestion. Three scheduling services are

 

supported: Strict Priority Queuing (SPQ), Weighted Round

 

Robin (WRR) and Weighted Fair Queuing (WFQ). 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

Multicast VLAN Registration (MVR) is designed for applications

Registration (MVR)

(such as 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.

 

 

IP Multicast

With IP multicast, the Switch delivers IP packets to a group of

 

hosts on the network - not everybody. In addition, the Switch

 

can send packets to Ethernet devices that are not VLAN-aware

 

by untagging (removing the VLAN tags) IP multicast packets.

 

 

RIP

RIP (Routing Information Protocol) allows a routing device to

 

exchange routing information with other routers.

 

 

VRRP

Virtual Router Redundancy Protocol (VRRP), defined in RFC

 

2338, allows you to create redundant backup gateways to

 

ensure that the default gateway of a host is always available.
