DESCRIPTION OF SOFTWARE FEATURES
The switch provides a wide range of advanced performance enhancing
features. Flow control eliminates the los s of packets due to bottlenecks
caused by port saturation. Storm suppression prevents broadcast,
multicast, and unknown unicast tr affic storms from engulfing the network.
Untagged (port-based) and tagged VLANs provide traffic security and
efficient use of network bandwidth. CoS priority queueing ensures the
minimum delay for moving real-time multimedia data across the network.
While multicast filtering provides support for real-time network
applications.
Some of the management features are brief l y described below.
CONFIGURATION
BACKUP AND
RESTORE
You can save the current co nfiguration settings to a file on the
management station (using the web interface) and later download this file
to restore the switch configuration settings.
AUTHENTICATION This switch authenticates management access via a web browser. User
names and passwords can be configured locally Port-based authentication
is also supported via the IEEE 802.1X protocol. This protocol uses
Extensible Authentication Protocol over LANs (EAPOL) to request user
credentials from the 802.1X client, and then uses the EAP between the
switch and the authentication server to verify the client’s right to access
the network via an authentication server (i.e., RADIUS server).
PORT CONFIGURATION Yo u can manually configure the speed and dup l ex mode, and flow control
used on specific ports, or use auto-negotiation to detect the connection
settings used by the attached device. Use the full-du plex mode on ports
whenever possible to double the throughput of switch connections. Flow
control should also be enabled to control network traffic during periods of
congestion and prev ent th e los s of packet s when p ort bu ffer thresholds are
exceeded. The switch supports flow control based on the IEEE 802.3x
standard (now incorporated in IEEE 802.3-2005).
RATE LIMITING This feature controls the maxim u m rate for traffic tran smitted or received
on an interface. Rate limiting is configu red on interfaces at the edge of a
network to limit traffic into or out of the network. Traffic that falls within
the rate limit is trans mitted, while packets that exceed the acceptable
amount of traffic are dropped.
PORT MIRRORING The switch can unobtru sively mirror tr affic from any po rt to a monitor port.
You can then attach a protocol analyzer or RMON probe to this port to
perform traffic analysis and verify connection integrity.

| Introduction
PORT TRUNKING Ports can be combined into an aggregate connection. Trunks can be
manually set up or dynamically configured using Link Aggregation Control
Protocol (LACP – IEEE 802.3-2005). The additional ports dramatically
increase the throughput across any connection, and prov ide redundancy by
taking over the load if a port in the trunk should fail. The s witch supports
up to 8 trunks.
STORM CONTROL Broadcast, multicast and unknown unicast storm suppression prevents
traffic from overwhelming the network.When enabled on a port, the level of
broadcast traffic passing through the port is restricted. If broadcast traffic
rises above a pre-defined thres hold, it will be throttled until the level falls
back beneath the threshold.
STATIC ADDRESSES A static address can be assigned to a specific interface on this switch.
Static addresses are bound to the assigned interface and wi ll not be
moved. When a static address is seen on another interface, the address will
be ignored and will not be written to the address table. Static addresses
can be used to provide network security by restricting access for a known
host to a specific port.
IEEE 802.1D BRIDGE The switch supports IEEE 802.1D transparent bridging. The address table
facilitates data switching by learning addresses, and then filte ring or
forwarding traffic bas ed on this informati on. The addre ss table suppo rts up
to 16K addresses.
STORE-AND-FORWARD
SWITCHING
SPANNING TREE
The switch copies each frame into its memory before forwarding them to
another port. This ensures that all frames are a standard Ether net size and
have been verified for accuracy with the cyclic redundancy check (CRC).
This prevents bad frames from enter ing the network and wasting
bandwidth.
To avoid dropping frames on congested ports, the switch provides 448 KB
for frame buffering. Thi s buf fer can queue packets awaiting transmission
on congested networks.
The switch supports these spanning tree protocols:
ALGORITHM
◆ Spanning Tree Protocol (STP, IEEE 802.1D) – Supported by using the
STP backward compatible mode provided by RSTP. STP provides loop
detection. When there are multiple physical paths between segments,
this protocol will choose a single path and disable all others to ensure
that only one route exists between any two stations on the networ k.
This prevents the creation of network loops. However, if the chosen
path should fail for any reason, an alternate path will be activated to
maintain the connection.

◆ Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol
VIRTUAL LANS The switch supports up to 256 VLANs. A Virtual LAN is a collection of
network nodes that share the same collision domain regardless of their
physical location or connection point in the network. The switch supports
tagged VLANs based on the IEEE 802.1Q standard. Members of VLAN
groups can be manually assigned to a specifi c set of VLANs. This allows the
switch to restrict traffic to the VLAN groups to which a user has been
assigned. By segmenting your network into VLANs, y ou can:
◆ Eliminate broadcast storms which severely degrade performance in a

flat network.
◆ Simplify network management for node changes/moves by remotely
configuring VLAN membership for any port, rather than having to
manually change the network conn ection.
◆ Provide data security by restricting all traffic to the originating VLAN.
TRAFFIC
PRIORITIZATION
This switch prioritizes each packet based on the require d level of service,
using eight priority queues with strict, W e ighted Fair Queuing, or W eig hted
Round Robin Qu euing. It uses IEEE 802.1p and 802.1Q tags to prioritize
incoming traffic based on input from the end-s tation application. These
functions can
data and best-effort data.
This switch also supports several common methods of prioritizing layer 3/4
traffic to meet app lication re quiremen ts . Traffic can be prioriti ze d based on
the priority bits i n the IP fr ame’s Type of Service (ToS) octet or the number
of the TCP/UDP port. When these services are enabled, the priorities are
mapped to a Class of Service value by the switch, and the traf fic th en sent
to the corresponding output queue.
be used to provide independent priorities for delay-sensitive
MULTICAST FILTERING Specific multicast traffic can be assigned to its own VLAN to ensure that it
does not interfere with normal networ k traffic and to guarantee real-time
delivery by setting the required priority level for the designated VLAN. The
switch uses IGMP Snooping and Query to manage multicast group
registration.

2 INITIAL SWITCH CONFIGURATION
This chapter includes information on connecting to the switch and basic
configuratio n procedures .
The switch inclu d es a bu il t-in network management agent. The ag e n t
offers a web-based management interface, and it also supports
management through SNMP (Simple Network Management Protoc ol).
The switch’s web management interfac e allo ws you to conf igu r e swit ch
parameters, monitor port conne ctions, and display statistics using a
standard web browser such as Internet Explorer 5.x or above, Netscape
6.2 or above, and Mozilla Firefox 2.0 or above. The web management
interface can be accessed from any computer attached to the network.
CONNECTING TO THE SWITCH
SETTING AN IP
DDRESS

To make use of the management features of your switch, you must first
configure it with an IP address that is compatible with the network it is
being installed in. This should be done before you permanently install the
switch in the network.
N
OTE
:
By default, the IPv4 address for this switch is set to 192.168.1.1
with subnet mask 255.255.255.0.
Follow this procedure:
1. Place your switch close to the PC that you intend to us e for
configuration. It helps if you can see the front pane l of the switch while
working on your PC.
2. Connect the Ethernet port of your PC to any port on the front panel of
your switch. C o nnect p o w er to the switch a nd verify that you h a ve a
link by checking the front-panel LE Ds.
3. Check that your PC has an IP address on the same subnet as the
switch. The default IP address of the switch is 192.168.1.1 and the
subnet mask is 255.255.255.0, so the PC and switch are on the same
subnet if they both have addresses that start 192.168.1.x. If the PC
and switch are not o n the same su bnet, y ou must manual ly set the PC ’ s
IP address to 192.168.1.x (where “x” is any number from 2 to 255). If
