Discovering Switches
When the utility is launched, it immediately searches the network for ProSafe® Plus switches.
Note: Local PC firewall applications such as Symantec Endpoint
Protection can prevent the utility from communicating with the
switches. If the utility is unable to discover your switches and you are
using a local firewall, you will need to turn off the firewall function in
order for discovery to work.
Within a few seconds the utility will discover and list all ProSafe® Plus switches in your
network or in the same broadcast domain. Discovery will continue through the network until
blocked by a router or firewall.
The discovered switches are displayed as shown below.
You can now select a switch to configure or display its status.
At this point you can select an alternate language for the Utility user interface. Click on the
Select Language pull down menu and click on the desired language. You will be asked to
restart the Utility to enable the selected language.

MultiCast
IGMP Snooping
Internet Group Management Protocol (IGMP) Snooping is a feature that allows a switch to
forward multicast traffic intelligently on the switch. Multicast IP traffic is traffic that is destined
to a host group. Host groups are identified by class D IP addresses, which range from
224.0.0.0 to 239.255.255.255. Based on the IGMP query and report messages, the switch
forwards traffic only to the ports that request the multicast traffic. This prevents the switch
from broadcasting the traffic to all ports and possibly affecting network performance.
To enable or disable IGMP snooping:
•
Select Disable or Enable for IGMP Snooping Status and click Apply.
or
•
You can also change the VLAN for which the IGMP Snooping to be enabled by entering a
valid VLAN ID for the field "VLAN ID Enabled for IGMP Snooping"; and clicking Apply.
This field is greyed out if VLAN is not enabled.
Validate IGMPv3 IP header:
Some of the Network devices may not conform to the IGMPv3 standard. When ‘Validate
IGMPv3 IP header’ option is enabled, IGMP messages are required to have TTL = 1, ToS
Byte = 0xC0 (Internetwork Control), and router alert IP option (9404) set; otherwise, the
packets will be ignored.
Block Unknown MultiCast Address:
When enabled, multicast packets are forwarded only to the ports that are in the Multicast
group learnt from IGMP snooping. All unknown multicast packets are dropped.

ProSafe Unmanaged Plus Switch Configuration Utility User Guide
VLAN Overview
Virtual LANs are made up of networked devices grouped together logically into separate
networks. The Switch Configuration Utility allows you to group ports on a switch to create a
virtual network made up of the devices connected to the ports. VLANs can be grouped using
Port Based or 802.1Q criteria
.
Port Based - allows you to assign ports to virtual networks. Data from a port that is a
member of a VLAN group will be restricted to other members of that VLAN group. This is an
easy way to partition a network into private sub networks.
802.1Q - allows you to create virtual networks using 802.1Q criteria. When using 802.1Q
VLAN configuration, you configure ports to be a part of a VLAN group. When a port receives
data tagged for a VLAN group, the data will be discarded unless the port is a member of the
VLAN group. This technique is useful if you need to communicate with devices outside of
your local network as well as still receiving data from other ports not in your VLAN group. It
requires that you know the VLAN group IDs used.
22 | Chapter 3: Virtual LAN Configuration
ProSafe Unmanaged Plus Switch Configuration Utility User Guide
Port Based Configuration
Port Based Virtual LAN configuration assigns ports on the selected switch to a Virtual LAN
Group. The number of VLANs that can be created is limited to the number of ports on the
switch. The Basic Port Based VLAN Configuration page is designed to help you to partition
your network into different segments. Ports with the same ID are grouped into the same
VLAN group. If all the VLAN groups share the same uplink to the Internet or servers, enter

VLAN Membership
To add ports to a VLAN group:
1. Select VLAN Membership from the menu on the left. The VLAN Membership screen
displays.
2. Select the VLAN group you want to configure from the VLAN Identifier pull down list
3. Check the boxes for the ports you want to add to the VLAN group. You can use the Group
Operation commands to add all ports or clear the current selections.
Note: Some switches allow Port Tagging on the VLAN Membership
screen. See Port Tagging on page 25.
4. Click on Apply. Return to the VLAN Configuration screen to verify your selections.
Port PVID
A Port Default VLAN ID (PVID) is a VLAN ID tag that the switch will assign to data packets it
receives that are not already addressed (tagged) for a particular VLAN group. If you have a
PC on port 6 and you want it to be a part of VLAN group 2, you would configure port 6 to
automatically add a PVID of 2 to all data received from the PC. This will ensure that the data
from the PC on port 6 can only be seen by other members of VLAN group 2.
You can only assign one PVID to a port.
To assign a PVID to a port:
1. Select a switch.
2. Select VLAN > 802.1Q > Advanced > Port PVID. The Port PVID screen displays.
3. Select the port you want to configure.
4. Enter the PVID you want to assign to the ports and click Apply.
Port Tagging
Port tagging allows a port to add VLAN ID tags to data packets sent through the port. The tag
identifies the VLAN that should receive the data.
Some switches allow Port Tagging to be done on the VLAN Membership screen. If so the
port check boxes allow you to select U (un tagged) or T (tagged) in addition to adding the port
to the VLAN group. This causes the data for an individual port to be tagged (associated) with
a VLAN group.

QoS Overview
There are many different classes of data that can be sent across a network. Depending on
the volume of traffic on the network and the capacity of the equipment in the network, data
can be delayed, or lost and retransmitted before reaching its destination. Normally this is not
a problem since the data is reassembled at the destination.
If the data consists of text or numeric data to be stored on the destination computer, the user
would not notice the delay. But if the data was voice, streaming video, or other delay sensitive
data, delays would be undesirable. Video sequences would be jerky and voice
communication would have annoying gaps.
The QoS (Quality of Service) feature in the ProSafe® Plus switches allows you to control the
flow of data passing through the switch.
•
QoS global configuration assigns priorities to data.
•
Rate Limit sets limits on transmission rates for data passing through the switch.
•
Broadcast Filtering blocks mass transmissions of broadcast packets from being
forwarded to all ports.
All of the QoS features have default settings. It is not necessary to configure any settings in
order to use the ProSafe® Plus switches.
The following table lists the default settings.

QoS Global Configuration
Global configuration allows you to assign priorities for how data will be transmitted by the
switch. Priority can be assigned either by port number (Port Based) or by the type of data
being transmitted (802.1p based). You would typically want to assign a low priority for normal
classes of data (email, internet browsing, and ordinary data transfers) and high priority to
video, voice, and other delay sensitive data.
Port Based Priority
Port-based priority works by assigning a priority to all data passing through a particular port.
A higher priority will transmit data with a minimum of delays. If packets arrive at several ports
at the same time, the ports configured as higher priority will transmit their packets first. This
means that you need to determine which ports are going to carry delay sensitive data.
Some switches allow you to select between two priority levels (High and Low). Others allow
four levels (High, Medium, Normal, and Low).
2 priority levels

4 priority levels
To assign Port Based priorities:
1. Select System and click on the radio button for the switch you want to configure.
2. Select QoS. The QoS Global Configuration screen displays.
3. Select the ports that you want to have that priority.
4. Select a priority level that you want to assign from the list at the bottom of the display.
5. Click Apply. The selected ports will be displayed with the new priority.
6. Repeat for the remaining ports.
802.1p Based Priority
802.1p-based priority uses a header in the data packet that identifies the class of data in the
packet (for example, voice or video). When 802.1p based priority is used, the switch reads
information in the packet header to determine the priority to assign to the packet. When
802.1p Based Priority is used, all ports on the switch check the packet header and transmit
the packet with a priority determined by the packet content.
To select 802.1p Based priority:
1. Select System and click on the radio button for the switch you want to configure.
2. Select QoS. The QoS Global Configuration screen displays.
3. Select the 802.1p Based radio button. A message will display warning you that previous
QoS settings for the switch will be lost.
4. Click Yes. Data will now be processed based on 802.1p priority tags in the data.

Rate Limiting
You can limit the rate at which the switch accepts incoming data and the rate that it
retransmits outgoing data. you can set rate values. The rate choices vary depending on the
switch model.
Rate limiting can be set for a port in addition to other QoS settings. If a port has a rate limit
set, the switch will restrict the acceptance or retransmission of data to the values configured.
To configure Rate Limiting:
1. Select System and click on the radio button for the switch you want to configure.
2. Select QoS > Rate Limit. The QoS Rate Limit screen displays.
3. Select one or more ports then select ingress and egress rates to assign.
4. Click Apply. The rates will be displayed opposite the selected ports.
5. Repeat for the remaining ports.

Broadcast Filtering
A switch can be configured to block massive transmission of broadcast packets being
forwarded to every port on the same VLAN. This is also known as broadcast storm
protection.
Failure to block broadcast storm packets can cause a delay or halt to other data. Some
switches allow you to select a Storm Control Rate for each port, others assign a
predetermined Storm control rate for all ports on the switch.
To configure Broadcast Filtering:
1. Select System and click the radio button for the switch you want to configure.
2. Select QoS > Broadcast Filtering to display the QoS Broadcast Filtering screen.
3. Select Enable.
If the selected switch supports configuring individual ports, a Storm control rate screen
will be displayed. If the selected switch does not support individual port configuration, all
of the ports will be set to a predetermined Storm control rate.
4. If the ports can be configured, select one or more ports, and the desired Storm control rate.
5. Click Apply.
