FEATURE

DESCRIPTION

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. 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.

 

 

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.

 

 

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.

 

 

Link Aggregation

Link aggregation (trunking) is the grouping of physical ports

 

into one logical higher-capacity link. You may want to trunk

 

ports if for example, it is cheaper to use multiple lower-speed

 

links than to under-utilize a high-speed, but more costly,

 

single-port link.

 

 

Port Authentication and

For security, the Switch allows authentication using IEEE

Security

802.1x with an external RADIUS server and port security that

 

allows only packets with dynamically learned MAC addresses

 

and/or configured static MAC addresses to pass through a port

 

on the Switch.

 

 

Authenticatio and

The Switch supports authentication and authorization services

Authorization

via RADIUS and TACACS+ AAA servers.

 

 

Device Management

Use the web configurator or commands to easily configure the

 

rich range of features on the Switch.
