FEATURE

DESCRIPTION

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. The following 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.

 

 

Bandwidth Control

Bandwidth control means defining a maximum allowable

 

bandwidth for incoming and/or out-going traffic flows on a port.

 

 

Broadcast Storm Control

Broadcast storm control limits the number of broadcast,

 

multicast and destination lookup failure (DLF) packets the

 

Switch receives per second on the ports.

 

 

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.

 

 

Two Rate Three Color

Two Rate Three Color Marker (trTCM, defined in RFC 2698) is a

Marker

type of traffic policing that identifies packets by comparing

 

them to two user-defined rates: the Committed Information

 

Rate (CIR) and the Peak Information Rate (PIR).

 

 

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 allow the Switch to communicate with

 

management stations not reachable via the default gateway.

 

 

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.

 

 

STP (Spanning Tree

(M)(R)STP detects and breaks network loops and provides

Protocol) / RSTP (Rapid

backup links between switches, bridges or routers. It allows a

STP)/MSTP (Multiple

Switch to interact with other (M)(R)STP-compliant switches in

Spanning Tree Protocol)

your network to ensure that only one path exists between any

 

two stations on the network.

 

 

Loop Guard

Use the loop guard feature to protect against network loops on

 

the edge of your network.

 

 

IP Source Guard

Use IP source guard to filter unauthorized DHCP and ARP

 

packets in your network.
