Differentiated Services
(DiffServ)

With DiffServ, the Switch marks packets so that they receive
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
Protocol) / RSTP (Rapid
STP)/MSTP (Multiple
Spanning Tree Protocol)

(M)(R)STP detects and breaks network loops and provides
backup links between switches, bridges or routers. It allows a
Switch to interact with other (M)(R)STP-compliant switches in
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
Security

For security, the Switch allows authentication using IEEE
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
Authorization

The Switch supports authentication and authorization services
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.
