Set Up a Fixed IP Address for the Switch

By default, the switch receives an IP address from a DHCP server (or a router that functions as a DHCP server) in your network. However, the DHCP server might not always issue the same IP address to the switch. For easy access to the switch local browser interface, you can set up a fixed (static) IP address on the switch. This allows you to

Your Network

User Manual18Install and Access the Switch in

8-Port Gigabit Ethernet Smart Managed Plus Switch Model GS908E

manage the switch anytime from a mobile device because the switch IP address remains the same.

To change the IP address of the switch, you can connect to the switch by one of the following methods:

Through a network connection. If the switch and your computer are connected to

• the same network (which is the most likely situation), you can change the IP address of the switch through a network connection (see Set Up a Fixed IP Address for the Switch Through a Network Connection on page 19).

Through a direct connection. In the unlikely situation that the switch is not connected

• to a network, or for some reason you cannot connect to the switch over a network connection, you can change the IP address of the switch by using an Ethernet cable and making a direct connection to the switch (see Set Up a Fixed IP Address for the Switch by Connecting Directly to the Switch Off-Network on page 20).

Set Up a Fixed IP Address for the Switch Through a Network Connection

Optimize the Switch Performance

This chapter describes how you can optimize the performance of the switch.

The chapter contains the following sections:

• Manually Set the Quality of Service Mode and Port Rate Limits

• Manage Broadcast Filtering and Set Port Storm Control Rate Limits

• Manage Custom Performance Preset Modes

• Manage Individual Port Settings

8-Port Gigabit Ethernet Smart Managed Plus Switch Model GS908E

Manually Set the Quality of Service Mode and Port Rate Limits

Instead of using preset performance modes, you can manually set the Quality of Service (QoS) modes to manage traffic:

Port-based QoS mode. Lets you set the priority (low, medium, high, or critical) for

• individual port numbers and lets you set rate limits for incoming and outgoing traffic for individual ports. If broadcast filtering is enabled, you can also set the storm control rate for incoming traffic for individual ports.

802.1P/DSCP QoS mode. Applies pass-through prioritization that is based on

• tagged packets and lets you set rate limits for incoming and outgoing traffic for individual ports. If broadcast filtering is enabled, you can also set the storm control rate for incoming traffic for individual ports. This QoS mode applies only to devices that support 802.1P and Differentiated Services Code Point (DSCP) tagging. For devices that do not support 802.1P and DSCP tagging, ports are not prioritized but the configured rate limit is still applied.

You can limit the rate of incoming traffic, outgoing traffic, or both on a port to prevent the port (and the device that is attached to it) from taking up too much bandwidth on the switch. Rate limiting, which you can set for individual ports in either QoS mode, simply means that the switch slows down all traffic on a port so that traffic does not exceed the limit that you set for that port. If you set the rate limit on a port too low, you might, for example, see degraded video stream quality, sluggish response times during online activity, and other problems.

Use Port-Based Quality of Service and Set Port Priorities

Port-based priority is the default QoS mode on the switch.

Note: If the QoS mode on the switch is 802.1P/DSCP, we recommend that you first save your current QoS settings as a custom preset mode before you change the QoS

mode to the Port-based mode. For more information, see Save Your Quality of Service Settings as a Custom Preset Mode on page 33.

For each port, you can set the priority and the rate limits for both incoming and outgoing traffic:

Port priority. The switch services traffic from ports with a critical priority before traffic

• from ports with a high, medium, or low priority. Similarly, the switch services traffic from ports with a high priority before traffic from ports with a medium or low priority. If severe network congestion occurs, the switch might drop packets with a low priority.

User Manual28Optimize the Switch

Performance

8-Port Gigabit Ethernet Smart Managed Plus Switch Model GS908E

Port rate limits. The switch accepts traffic on a port at the rate (the speed of the

• data transfer) that you set for incoming traffic on that port. The switch transmits traffic from a port at the rate that you set for outgoing traffic on that port. You can select each rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Note: If you set a port rate limit, the actual rate might fluctuate, depending on the type of traffic that the port is processing.

To use the Port-based QoS mode and set the priority and rate limits for ports:

Open a web browser from a computer that is connected to the same network as the switch or to the switch directly through an Ethernet cable.

2. Enter the IP address that is assigned to the switch. The login page displays.

Click the APPLY button. Your settings are saved and the EDIT RATE LIMITS page closes.

Use 802.1P/DSCP Quality of Service

In the 802.1P/DSCP QoS mode, the switch uses the 802.1P or DSCP information in the header of an incoming packet to prioritize the packet. With this type of QoS, you cannot control the port prioritization on the switch because the device that sends the traffic (that is, the packets) to the switch prioritizes the traffic. However, you can set the rate limits for individual ports on the switch.

The switch accepts traffic on a port at the rate (the speed of the data transfer) that you set for incoming traffic on that port. The switch transmits traffic from a port at the rate that you set for outgoing traffic on that port. You can select each rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Note: If the QoS mode on the switch is Port-based, we recommend that you first save your current QoS settings as a custom preset mode before you change the QoS mode

to the 802.1P/DSCP QoS mode. For more information, see Save Your Quality of Service Settings as a Custom Preset Mode on page 33.

Manage Broadcast Filtering and Set Port Storm Control Rate Limits

A broadcast storm is a massive transmission of broadcast packets that are forwarded to every port on the switch. If they are not blocked, broadcast storm packets can delay or halt the transmission of other data and cause problems. However, you can block broadcast storms on the switch.

You can also set storm control rate limits for each port. Storm control measures the incoming broadcast, multicast, and unknown unicast frame rates separately on each port, and discards the frames if the rate that you set for the port is exceeded. By default, no storm control rate limit is set for a port. You can select each storm control rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Use VLANS for Traffic Segmentation

The chapter contains the following sections:

• VLAN Overview

• Manage Port-Based VLANs

• Manage 802.1Q-Based VLANs

• Deactivate the Port-Based or 802.1Q-Based VLAN Mode and Delete All VLANs

8-Port Gigabit Ethernet Smart Managed Plus Switch Model GS908E

VLAN Overview

Virtual LANs (VLANs) are made up of networked devices that are grouped 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.

You can group ports in VLANs using either port-based or 802.1Q criteria:

Port-based VLANs. Assign ports to virtual networks. Ports with the same VLAN ID

• are placed in the same VLAN. The number of VLANs is limited to the number of ports on the switch. This feature provides an easy way to partition a network into private subnetworks. If the switch is the only switch in your network and you do not need a VLAN to function across multiple network devices (such as a router, another switch, a WiFi AP, or any network device that supports VLANs), we recommend that you use a port-based VLAN.

802.1Q VLANs. Create virtual networks using the IEEE 802.1Q standard. 802.1Q

• uses a VLAN tagging system to determine which VLAN an Ethernet frame belongs to. To use an 802.1Q VLAN, you must know the VLAN ID. In the 802.1Q VLAN configuration that is supported on the switch, VLAN 1 is added to the switch and all ports (1 through 8) are untagged members of VLAN 1. You can tag ports, untag ports, exclude ports, add more VLANs, assign a different VLAN to a port, manage port PVIDs, and manage a voice VLAN. When a port receives data that is untagged, the data is delivered normally. However, when a port receives data that is tagged for a VLAN, the data is discarded unless the port is a member of that VLAN. This technique is useful for communicating more securely with devices outside your local network as well as receiving data from other ports that are not in the VLAN.

The following table provides an overview of VLAN features that are supported on the switch.

Specify a Port PVID for an 802.1Q-Based VLAN

A default port VLAN ID (PVID) is a VLAN ID tag that the switch assigns to incoming data packets that are not already addressed (tagged) for a particular VLAN. For example, if you connect a computer to port 6 of the switch and you want it to be a part of VLAN 2, add port 6 as a member of VLAN 2 and configure port 6 to automatically add a PVID of 2 to all data that the switch receives from the computer. This step makes sure that the data from the computer on port 6 can be seen only by other members of VLAN 2. You can assign only one PVID to a port.

Note: If you did not yet create an 802.1Q-based VLAN, all ports are assigned PVID 1 and you cannot assign another PVID to a port. In this situation, first create a custom

Manage the Switch in Your Network

This chapter describes how you can manage the switch in your network.

The chapter contains the following sections:

• Manage Switch Discovery Protocols

• Manage Multicast

• Set Up Static Link Aggregation

• Change the IP Address of the Switch

• Reenable the DHCP Client of the Switch

8-Port Gigabit Ethernet Smart Managed Plus Switch Model GS908E

Manage Switch Discovery Protocols

It is important to know the IP address of the switch so that you can access the local browser interface of the switch. The switch supports Universal Plug and Play (UPnP), Bonjour, and NETGEAR Switch Discovery Protocol (NSDP), which are protocols that can discover the switch. A device that functions in the same network as the switch and that supports one of these protocols can discover the switch and obtain the IP address.

As a security measure, you can disable one or more discovery protocols. However, we recommend that you leave at least one discovery protocol enabled so that a device can discover the switch if the switch IP address changes.

Manage Universal Plug and Play

A Windows-based device that supports Universal Plug and Play (UPnP) can discover the switch in the network so that you can find the switch IP address and log in to the local browser interface of the switch. UPnP is enabled by default. You can disable UPnP for security reasons.

To manage UPnP:

Open a web browser from a computer that is connected to the same network as the switch or to the switch directly through an Ethernet cable.

Manage Multicast

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. Internet Group Management Protocol (IGMP) snooping allows the switch to forward multicast traffic intelligently. Based on the IGMP query and report messages, the switch forwards traffic only to the ports that request the multicast traffic rather than to all ports, which could affect network performance.

IGMP snooping helps to optimize multicast performance and is especially useful for bandwidth-intensive IP multicast applications such as online media streaming applications.

Manage IGMP Snooping

Internet Group Management Protocol (IGMP) snooping is enabled by default. Under some circumstances you might want to temporarily disable IGMP snooping.

Click the APPLY button. Your settings are saved.

Set Up Static Link Aggregation

Static link aggregation on the switch allows you to combine multiple Ethernet ports into a single logical link. Your network devices treat the aggregation as if it were a single link. Depending on how link aggregation is set up in your network, the link supports either increased bandwidth (a larger pipe) or fault tolerance (if one port fails, another one takes over).

The switch supports two static LAGs with up to four ports each. That means that one static LAG can support a link of up to 4 Gbps.

Note: The switch does not support Link Aggregation Control Protocol (LACP).

You set up static link aggregation on the switch through a link aggregation group (LAG) in the following order:

1. Set up the LAG on the switch (see Set Up a Link Aggregation Group on page 66).

Connect the ports that must be members of the LAG on the switch to the ports that must be members of the LAG on another device in your network (see Make a Link Aggregation Connection on page 67).

User Manual65Manage the Switch in Your

Network

3. Enable the LAG on the switch (see Enable a Link Aggregation Group on page 67) and on the other device.

Set Up a Link Aggregation Group

You set up static link aggregation on the switch by adding up to four ports to a link aggregation group (LAG) and by enabling the LAG. However, for a LAG to take effect, you first must make sure that all ports that participate in the LAG (that is, the ports on both devices) use the same speed, duplex mode, and flow control setting (see Manage Individual Port Settings on page 37 for information about changing these settings on the switch) and you must set up a physical link aggregation connection (see Make a Link Aggregation Connection on page 67).

After you set up a link aggregation group and make a physical link aggregation connection, you can enable the link aggregation group (see Enable a Link Aggregation Group on page 67).

To set up one or more link aggregation groups on the switch:

Open a web browser from a computer that is connected to the same network as the switch or to the switch directly through an Ethernet cable.

2. Enter the IP address that is assigned to the switch. The login page displays.

Make a Link Aggregation Connection

Before you make a physical link aggregation connection to another network device (usually a router or another switch) that also supports link aggregation, you must first set up a link aggregation group (LAG) on the switch (see Set Up a Link Aggregation Group on page 66). If you do not, the LAG cannot take effect.

All ports that participate in a LAG (that is, the ports on both devices) must use the same speed, full duplex mode, and flow control setting. For information about changing these settings on the switch, see Manage Individual Port Settings on page 37.

To make link aggregation connections between the switch and another network device:

Using Ethernet cables, connect each port that must be a member of the LAG on the switch to each port that must be a member of the same LAG on another network device.

LAG 1 can include ports 1 through 4. LAG 2 can include ports 5 through 8.

The port numbers on the other network device do not matter as long as the ports on the other network device are members of the same LAG, the LAG consists of the same total number of ports, and the ports use the same speed, full duplex mode, and flow control setting as the ports in the LAG on the switch.

Enable a Link Aggregation Group

After you set up a link aggregation group (see Set Up a Link Aggregation Group on page 66) and make a physical link aggregation connection (see Make a Link Aggregation Connection on page 67), you can enable the link aggregation group.

Note: You must also enable the link aggregation group on the other network device.

Manage Auto-Diagnostics and Clear Events or Problems

Auto-diagnostics consists of the following monitoring options, all of which are enabled by default:

Identify blocked ports. The switch can automatically identify a blocked port that is

• caused by a loop condition. If this condition occurs, the Power LED lights or blinks solid amber and the icon for the affected port on the AUTO-DIAGNOSTICS page displays blue. If the condition is resolved, the Power LED is reset automatically. Regardless of whether the condition is resolved, you can clear the event on the AUTO-DIAGNOSTICS page and reset the Power LED.

Identify ports with CRC error packet events. The switch can automatically identify

• a CRC error packet event. If this condition occurs, the Power LED lights or blinks solid amber and the icon for the affected port on the AUTO-DIAGNOSTICS page displays blue. You can clear the event on the AUTO-DIAGNOSTICS page and reset the Power LED. This action does not affect the statistics that are shown in the CRC Error Packets column on the Port Statistics page (see View the Port Statistics on page

81). However, if you clear the statistic on the Port Statistics page, the event on the AUTO-DIAGNOSTICS page is also cleared and the Power LED is reset.

Identify ports with LAG problems. The switch can automatically identify whether

• a problem occurs with a port that is a member of a LAG or whether such a port is shut down. If this condition occurs, the Power LED lights or blinks solid amber and the icon for the affected port on the AUTO-DIAGNOSTICS page displays blue. Regardless of whether the condition is resolved, you can clear the event on the AUTO-DIAGNOSTICS page and reset the Power LED.

Identify an unsuccessful firmware update. The switch can automatically identify

• an unsuccessful firmware upgrade, including an attempt to load an invalid image. If a power cycle occurs during a firmware update, a notification does not occur. If an unsuccessful firmware update occurs, the Power LED lights or blinks solid amber and the FAILED button on the AUTO-DIAGNOSTICS page displays blue. You can clear the event on the AUTO-DIAGNOSTICS page and reset the Power LED.

You can enable and disable these monitoring options individually.

Note: If you restart the switch, all conditions are cleared. However, if you do not resolve a blocked port condition or a problem with a LAG port, the condition will occur again.

Manage Loop Prevention

By default, loop prevention is enabled. If the switch detects a loop, the switch blocks one of the ports that are part of the loop and the port LED for that port blinks at a constant speed. If two ports are part of a loop, the port with the highest port number is blocked. For example, if port 1 and port 2 are part of a loop, port 2 is blocked while port 1 continues to process traffic. The loop status (that is, port blocking and LED blinking) is cleared if the switch does not detect the loop for a period of four seconds.

Test a Cable Connection

You can use the cable diagnostic feature to easily find out the health status of network cables. If any problems exist, this feature helps to quickly locate the point where the cabling fails, allowing connectivity issues to be fixed much faster, potentially saving technicians hours of troubleshooting.

If an error is detected, the distance at which the fault is detected is stated in feet. (This is the distance from the port.)

To test one or more cable connections:

Open a web browser from a computer that is connected to the same network as the switch or to the switch directly through an Ethernet cable.

2. Enter the IP address that is assigned to the switch. The login page displays.

Troubleshooting

8-Port Gigabit Ethernet Smart Managed Plus Switch Model GS908E

Resolve a Subnet Conflict to Access the Switch

If you power on the switch before you connect it to a network that includes a DHCP server (or a router that functions as a DHCP server), the switch uses its own default IP address of 192.168.0.239. This subnet might be different from the subnet used in your network.

To resolve this subnet conflict:

1. Disconnect the Ethernet cable between the switch and your network.

Unplug the power adapter of the switch.

3. Reconnect the Ethernet cable between the switch and your network.

Plug the power adapter of the switch into an electrical outlet. The switch powers on. The DHCP server in the network discovers the switch and

assigns it an IP address that is in the correct subnet for the network.

Wall-Mount the Switch

The switch provides two mount holes on the bottom panel so that you can attach the switch to a wall. The switch package provides two screws and anchors for that purpose.

To attach the switch to a wall:

Locate the two mount holes on the bottom panel of the switch.

2. Locate the M3.5 x 16 mm screws and anchors in the switch package.

3. Mark and drill two mounting holes in the wall where you want to mount the switch. The two mounting holes must be at a precise distance of 147.5 mm (5.8 in.) from

each other.

4. Insert the anchors into the wall and tighten the screws with a No. 2 Phillips screwdriver. Leave about 4 mm (about 0.125 in.) of each screw protruding from the wall so that

you can insert the screws into the holes on the bottom panel.

5. Line up the holes on the bottom panel with the screws in the wall and mount the switch to the wall.
