Virtual LAN Configuration
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.
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 'all' in the VLAN Group field for the port that you want to use for the uplink.
Basic Port Based VLAN Configuration
To assign members of a VLAN group using Basic Port-Based configuration:
1. Select the switch.
2. Select VLAN. This will display the Basic Port-Based VLAN configuration page.
3. Select Enable. A message will display asking if you want to delete previous VLAN settings.
Page 24
ProSafe® Plus Switch Configuration Utility User Guide
3-2 Virtual LAN Configuration
v1.0, February 2010
4. Click Yes. The Basic Port Based VLAN Configuration screen will display.
5. For each port to be added to the group, select the port and then the VLAN Group.
6. When you are finished adding ports to a particular VLAN Group, click Apply.
Advanced Port Based VLAN Configuration
The advanced port-based configuration uses a slightly different user interface to allow you to assign ports to
multiple VLAN groups.
To assign members of a VLAN group using Advanced Port-Based Configuration:
1. Select the switch.
2. Click on the VLAN tab. This will display the Port-Based VLAN configuration page.
3. Select Advanced. This will display the Advanced Port-Based VLAN configuration page.
4. Select Enable. A message will display asking if you want to delete previous VLAN settings.
5. Click Yes. The Advanced Port-Based VLAN configuration screen will display.
6. VLAN IDs are limited to the number of ports on the switch, 1-5 for a five port switch. Select a VLAN
ID from the VLAN identifier field and check the ports that you want to add to the VLAN and click
Apply. If you want to create more VLANs, repeat this step with another VLAN ID.
802.1Q Based Configuration
802.1Q VLAN configuration can be done using basic or advanced methods.
Basic 802.1Q VLAN Configuration
In Basic 802.1Q VLAN configuration you configure ports to a VLAN Group ID (1-4093 or all). To
configure ports using 802.1Q criteria:
1. Select the switch.
2. Select VLAN. This will display the Port-Based VLAN configuration page.
3. Select 802.1Q on the menu.
4. Select Enable.
5. For each port to be configured, enter the VLAN Group ID (1-4093 or all) in the field below the port.
6. When you are finished configuring ports, click Apply.
Advanced 802.1Q VLAN Configuration
In Advanced 802.1Q VLAN configuration you configure ports to a VLAN Group ID (1-4093 or all). The
advanced configuration feature allows you to create and update VLAN groups with additional information.

To add VLAN groups:
1. Enter the VLAN ID (1-4094) for the VLAN you want to configure in the VLAN ID field at the bottom
right of the screen and click Add. The new VLAN group will be displayed in the VLAN ID column.
2. Once you have created a new VLAN ID click on VLAN Membership to add ports to the group. See
“VLAN Membership” on page 3-3
To delete a VLAN group:
1. Select the boxes for the VLANs to be deleted. Selecting the box at the top of the column will select all
VLAN IDs.
2. Click Delete. The selected VLAN groups will be deleted.
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 to be done on the VLAN Membership screen. If so the port check
boxes will allow you to select U (un tagged) or T (tagged) in addition to adding the port to the VLAN
group. This will cause the data for an individual port to be tagged (associated) with a VLAN group.
See “Port Tagging” on page 3-4
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.

Quality of Service Configuration
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).

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 (for example, voice or
video) in the packet. When 802.1p based priority is used, the switch reads information in the packet header
to determine the priority to assign to the data packet. When 802.1p Based Priority is used, all ports on the
switch will check the packet header and transmit the packet according to its 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 choices for rates will 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 on the radio button for the switch you want to configure.
2. Select QoS > Broadcast Filtering. The QoS Broadcast Filtering screen displays.
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 are configurable, select one or more ports and the desired Storm control rate. Click Apply.
