Introduction

There is no separate User Guide manual for the NJ2000. The NJ2000 Web interface includes context relevant help on the administration Web pages.

Where you wish to consult this help without connecting to the Switch administration the help text is captured in this document.

System Information

This page provides an overview of the configuration of the switch. There are five different tables on this page:

System Identity - Displays general information about the switch. Address Information - Displays the IP Address configuration of the switch. Port Information - Displays the configuration of every port on the switch. Trunk Information - Displays membership information for all trunks. VLAN Information - Displays the membership information for all VLANs.

Note: This page displays an overview of the switch configuration. To change the switch configuration, use the Web Management-Interface pages referenced on this page.

There are two main buttons associated with this page:

HELP - Displays this window. REFRESH - Refreshes the page with the current switch configuration and status

information.

System Identity

This section contains general information about the switch. System Name, System Location, and System Contact are set in the SYSTEM > Name page. The Software Version changes when a new version of software is updated on the switch from the SYSTEM> Tools page. The Number of Ports, Hardware Version, and Serial Number values are created when the switch is manufactured

and cannot be changed.

Address Information

IP Address, Subnet Mask and Gateway IP Address are set from the SYSTEM > IP Address

page. Management VLAN and MAC Address are fixed during manufacture and are provided here for information.

Port Information

This table contains one row for each port on the switch. Each row is divided into eight columns as follows:

Port - The front-panel port number. Type - All ports on this switch are 10/100/1000BASE-T. Link Status - Up indicates that the port is connected to another device. Down indicates

there is no connection. The front-panel "image" that is always visible at the top of the page, also displays this information.

Speed/Duplex Status - An indication of the speed and duplex setting of the port. This is a

number, the speed in Mbps, followed by either FDX for full-duplex or HDX for halfduplex. This can be changed on the PORTS > Configuration page.

Flow Control Status - Enabled indicates that Flow Control has been enabled on the

PORTS > Configuration page.

Auto-negotiation - Auto-negotiation is Enabled by default and is only Disabled when a

Speed/Duplex setting other than Auto is selected on the PORTS > Configuration page.

Frame Type - Tagged means that the port will only send and receive VLAN-tagged

frames. When set to All the port will also send and receive untagged packets. See VLANS > Port Config for more information.

PVID - The Port VLAN ID. When Frame Type is set to All, untagged packets arriving on

the port will be associated with this VLAN. See VLANS > Port Config for more information.

Trunk Information

This table will be empty if no trunks have been configured from the TRUNKS > Membership page. The table has four columns as follows:

Trunk - The Trunk Label. T1 through T4 may appear in this column. Type - All trunks and ports on this switch are 10/100/1000M Trunk Status - An indication of the speed and duplex setting of the trunk. This is a

number, the speed in Mbps, followed by either Full for full-duplex or Half for half-duplex. This can be changed on the TRUNKS > Settings page.

Ports - The ports that are members of the trunk.

VLAN Information

VLANs can be added on the VLANS > VLAN Setup page. The two columns in this table are used as follows:

VLAN ID - A number in the range 1 - 4094 which identifies the VLAN. VLAN Members - A list of the ports that are members of the VLAN. By default, all ports

are members of VLAN 1.

The total number of octets received on the interface, including framing characters.

Received Unicast Packets

The number of subnetwork-unicast packets delivered to a higher-layer protocol.

Received Errors

The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.

Transmitted Multicast Packets

The total number of packets that higher-level protocols requested be transmitted, and which were addressed to a multicast address at this sub-layer, including those that were discarded or not sent.

Transmitted Broadcast Packets

The total number of packets that higher-level protocols requested be transmitted, and which were addressed to a broadcast address at this sub-layer, including those that were discarded or not sent.

Received High Priority Packets

Received Multicast Packets

The number of packets, delivered by this sub-layer to a higher (sub-)layer, which were addressed to a multicast address at this sub-layer.

You can display statistics on network traffic from the ports. These statistics can be used to identify potential problems with the switch (such as a faulty port or unusually heavy loading). All values displayed have been accumulated since the last system reboot, but can be reset to zero by clicking the CLEAR button. The current statistics are not displayed until you click the REFRESH button.

Transmitted Normal Priority Packets

The total number of transmitted packets that set as High Priority in the QoS settings.

There are two main buttons associated with this page:

REFRESH - Resends the information. CLEAR - Clears all counters and sets them back to zero.

System Name

This page allows you to change the System Name, System Location, and System Contact. The System Name is displayed on the Login page, and the SYSTEM > Information page.

System Name - The name of the switch. The System Name can be up to 24 characters long. System Location - Description of the switch location. The System Location can be up to 24 characters

long.

System Contact - The contact name for the switch. The System Contact can be up to 24 characters long.

Note: The System Name, System Location, and System Contact will accept all characters on the keyboard (i.e.:

numbers, upper-case and lower-case letters, and keyboard symbols).

IP Address

This page allows you to change the IP Address used by the switch.

DHCP Enabled - If enabled, the IP Address will be assigned from the DHCP server. If disabled, the IP

Address must be assigned manually.

Switch IP Address - The dot-separated IPv4 address used by the switch. Subnet Mask - The dot-separated IPv4 Subnet address used by the switch. If in doubt, set this to be the

same as the Subnet Mask used by your PC.

Gateway IP Address - The dot-separated IPv4 Gateway address used by the switch. If in doubt, set this to

be the same as the Default Gateway address used by your PC.

Note: If DHCP is enabled, the word "Fallback" will be added to the front of the other parameter names to indicate the usage of a manually assigned IP Address.

Note: If you change the IP address used by the switch you will lose contact with this Web Management-Interface and may have to change the IP address on your PC to reconnect.

Note: It is extremely important that you do not forget the IP Address of the switch. If you forget the IP Address you

will have to manually reset the switch to its factory defaults. See the Troubleshooting page for more details. Power cycle will not reset the IP Address.

There are three main buttons associated with this page:

HELP - Displays this window. APPLY - Updates the switch configuration. No changes are made to the configuration until this button is

pressed.

CANCEL - All changes made to the page are discarded and the switch configuration remains unchanged

Tools

On the Tools page, you can restore the switch to default settings, upgrade the firmware of the switch, or restart the switch.

Restore to Factory Defaults

Forces the switch to restore the original factory settings. To reset the switch, select “Reset to

Factory Defaults” from the drop-down list and click APPLY.

Upgrade Firmware

Upgrades the switch system firmware using a file provided by 3Com. Select “Upgrade

Firmware” from the Tools drop-down list then click on the “Browse” button to select the

firmware file. Normally you will use the .wrp file for the upgrade. Click the “APPLY”

button to upgrade the selected switch firmware file. After the file is successfully transferred, the switch will be automatically restarted/rebooted causing a temporary stopping all

communication to and through the unit. The “System Rebooting” window will appear

during the reboot process. After the reset is complete, the user interface displays the “login“ page.

You can download firmware files for your switch from the Support section of the 3Com web site at www.3com.com.
