NETGEAR website.
Discovering Switches
When the utility is launched, it immediately searches the network for ProSafe Plus switches.
Local computer 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 must turn off the firewall function in order for discovery
to work properly. After a few seconds the utility discovers and lists all ProSafe Plus switches
in your network or in the same broadcast domain. Discovery continues through the network
until blocked by a router or firewall.

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.
You can use either of the following methods to enable or disable IGMP snooping:
•
•
In the IGMP Snooping Status field, select Disable or Enable, and click Apply.
You can also change the VLAN for which the IGMP Snooping is enabled. In the VLAN ID
Enabled for IGMP Snooping field, enter a valid VLAN ID, and click Apply. This field is
grayed out if VLAN is not enabled.
Validate IGMPv3 IP header
Some network devices might not conform to the IGMPv3 standard. When the Validate IGMPv3
IP header option is enabled, IGMP messages are required to have TTL = 1, ToS Byte = 0xC0
(Internetwork Control), and the router alert IP option (9404) set; otherwise, the packets are
ignored.
Block Unknown MultiCast Address
When enabled, multicast packets are forwarded only to the ports that are in the multicast
group learned from IGMP snooping. All unknown multicast packets are dropped.
IGMP Snooping Static Router Port
You can select a port to be the dedicated IGMP snooping static router port if there is no IGMP
query in the network for the switch to discover the router port dynamically. Once a port is
selected as the static router port, all IGMP Join and Leave reports forward to it. If you select
any in this field, IGMP Join and Leave packets are sent to every port of the switch. Only the
GS105E switch supports the any setting in this field.

VLAN Overview
Virtual LANs are made up of networked devices grouped together logically into separate
networks. You can 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 is 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 is discarded unless the port is a member of the
VLAN group. This technique is useful 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 PVID
A Port Default VLAN ID (PVID) is a VLAN ID tag that the switch assigns to data packets it
receives that are not already addressed (tagged) for a particular VLAN group. If you have a
computer on port 6 and you want it to be a part of VLAN group 2, configure port 6 to
automatically add a PVID of 2 to all data received from the computer. This ensures that the
data from the computer 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 to 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
Global configuration allows you to assign priorities for how the switch transmits data. 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 transmits data with a minimum of delays. If packets arrive at several ports at
the same time, the ports configured as higher priority transmit their packets first. You must
determine which ports are going to carry delay sensitive data.

Some switches allow you to select between two priority levels (High and Low).
2 priority levels
Other switches allow four levels (High, Medium, Normal, and Low).
4 priority levels
To assign Port Based priorities:
1. Select System and click 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 are 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 select 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 displays 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 restricts the acceptance or retransmission of data to the values configured.
To configure Rate Limiting:
1. Select System and select 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 are 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.

If the selected switch supports configuring individual ports, a Storm Control Rate screen
is displayed. If the selected switch does not support individual port configuration, all of the
ports is 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.
