Management

Hubs themselves are rarely the cause of problems on the network. However, since hubs are the center point for many devices on the network, it’s a good place to start looking for problems.

There are four categories of management tasks:

• Configuring the hub or stack of hubs. This includes setting the IP configuration, naming the hubs, and disabling individual ports.

• Monitoring traffic. This helps to plan network expansion or make segmenting decisions.

• Finding malfunctioning devices such as LAN adapters in PCs.

• Finding wiring problems between an attached device and the hub.

There are several methods for managing hubs. You can use any combination.

• Manage with the onboard LCD or Console Manager. This method works best for initial setup or when the network goes down and you can’t access the hub with an SNMP application.

• Manage with Intel Device View for Web or LANDesk® Network Manager. These SNMP applications are tailored for Intel products and show a graphical representation of the hub.

• Manage with any other SNMP-compliant application. If you already use an SNMP application, you can manage hubs by compiling the hub’s MIB files into that application. File locations are listed on page 51.

Intel Cascade Cable

(product code EE110CC)

Managing multiple hubs

To manage multiple hubs, you must stack them using Intel Cascade Cables.

100 Mbps

10 Mbps

Connecting hubs with Intel Cascade Cables allows you to manage both 10 and 100 Mbps hubs with a sin

le Management Module.

Hub numbering

Once connected with Intel Cascade Cables, the Management Module numbers hubs from top to bottom, regardless of the placement of the Management Module.

Collision domain assignments

All hubs running at the same speed in the stack belong to the same collision domain. In the example below, all devices (PCs, print servers, and so on) connected to hubs 1 and 2 share 100 Mbps of bandwidth. All devices connected to hubs 3 and 4 share 10 Mbps of bandwidth.

The two collision domains don’t pass traffic to each other without optional bridging equipment (see the Intel Express 10/100 Stackable Hub User Guide that came with the hub for more information on bridging options).

The entire hub is called the chassis.

MIB identification

If you use a MIB browser, you can configure or view statistics for the hub at three levels – by hub (chassis), module, or port. The MIB file locations are listed on page 51.

Changing the LCD contrast

You can change the contrast so the display is viewable from different angles. For example, if the management module is located in a hub at the top of a rack.

• Make sure the Main menu is displayed with the Stats item

flashing.

– To darken: Press the Esc button for five seconds to enter

contrast mode. Keep pressing until the display turns darker.

– To lighten: Press the left arrow button for five seconds to enter

contrast mode. Keep pressing until the display turns lighter.

Viewing statistics

From the Stats menu, select the stat type, Domain or Port. Press

Domain 1 Collisions & usage per second appears. Press to display the

following graph. If there are two collision domains (10 and 100 Mbps hubs in the same stack) two graphs will be displayed.

Top bar shows collisions per second

collisions/usage

100Mb

Bottom bar shows % utilization

Each segment represents a value of 10 (each pixel within a segment is a value of 2). In this example, the 100 Mbps collision domain is 34% utilized and the collision count is 16 collisions per second.

2 Press any key to return to the Main menu. Port 1 Use the arrow keys to select the hub (from 1 to 8). Press 2 Use the arrow keys to select the port number (1 to 12 or

1 to 24). Press

3 Use the arrow keys to step through the different stats —packets,

collisions, auto-partitions, alignment errors, frames too long, runts, very long events, rate mismatches, late collisions, FCS errors, short events. While viewing a statistic, you can update by pressing . For more information on these statistics, see pages 31-35.

Changing the IP configuration

1 From the Config menu, select Set IP. Press 2 Select OK to continue or Cancel to return to the Main menu.

Press

3 Select Manual or BootP. Press

• If you selected Manual, use the arrow keys to scroll through

the range of values for each number, pressing to set.

• If you selected BootP, the Management Module searches for a

BOOTP server.

4 (Manual) Repeat step 3 for the Subnet mask and Default gateway. 5 When you’re finished, press the Reset button. This resets the

Management Module and all hubs in the stack. When the hub resets, attached devices temporarily lose connection, but the links are automatically re-established when the hub is back up.

Setting the sleep mode

Sleep mode displays information on the LCD when you leave it unattended – like a screen saver.

1 From the Config menu, select Sleep. 2 Set the wait time (time before sleep mode starts). You can set the

delay from 1 to 255 minutes. A setting of 0 turns off the sleep mode. Press

3 Choose what you want to display during sleep mode. Use the

arrow keys to select one of the options below. Press

Usage: The percent utilization of the collision domain or domains. Traps: A list of error conditions on the hub. For a list of supported

traps, see page 25. Name, Loc. (Location), or Contact: For more information on

these options, see page 17.

Text: User-defined text set via SNMP through LANDesk Network Manager or Device View for Web. Up to 32 characters can be displayed on the LCD.

Address: The current IP address of the Management Module.

4 Choose Yes if you want the management module to sleep now or

No to return to the Config menu. Press

Disabling a port

1 From the Config menu, select Ports. Press 2 Use the arrow keys to select the hub (from 1 to 8). Press 3 Use the arrow keys to select the port number (from 1 to 12 or

1 to 24). Press

4 Select Enable or Disable using the arrow keys.

Press

5 Press any key to return to the Config menu.

Setting the serial port baud

1 From the Config menu, select RS232. Press

2 Use the arrow keys to change the baud ( 9600, 19200, or 38400).

Press to set.

3 Press any key to return to the Config menu.

Viewing trap messages

1 From the Main menu, select Traps. Press 2 Use the right arrow key to view the traps. 3 At the end of the list choose whether you want to clear the trap

list. Use the arrow keys to select Yes or No and press .

For a list of supported traps, see page 25.

Viewing About information

1 From the Main menu, select About. Press 2 Use the arrow keys to view the IP address, Subnet mask, MAC

address, Version (software version of Management Module), and RS232 baud.

Accessing with the serial port

1 Use the enclosed null modem cable to connect the serial port of

your PC to the serial port of the Management Module.

2 Open a terminal emulation program (such as HyperTerminal in

Microsoft Windows* 95). Use these communication parameters:

• 9600 baud

• 8 data bits

• No parity

• 1 stop bit

• No flow control

3 Log into the Console Manager:

Enter username: [ ] Enter password: [ ]

By default, no password or username is assigned. See page 45 to assign them.

NOTE

Make sure you enable VT100 arrows in the Telnet application you’re using.

If you don’t, you won’t be able to use the arrow keys.

NOTE

If the screen doesn’t display correctly when connecting, press q. This will refresh it.

Accessing with Telnet

Telnet lets you access the Management Module in-band (over the network).

To use Telnet:

1 Make sure an IP address is assigned to the Management Module.

See pages 11 or 19 for instructions.

2 Open a Telnet application. In Windows 95, select Run from the

Start Menu. Type:

telnet E

3 From the Terminal menu, select Preferences. Make sure the

emulation type is VT-100/ANSI and VT100 Arrows are enabled.

4 From the Connect menu, select Remote System. Enter the IP

address of the Management Module and click Connect.

5 Log into the Console Manager:

Enter username: [ ] Enter password: [ ]

By default, no password or username is assigned. See page 45 to assign them.

Navigating

See below for navigation tips. On the top screen (see the next page) you can press the number of the menu item to select it. For example, selecting 1 will display the System Configuration screen.

WZ or T: Moves up or down to the next menu item. For example, pressing Z moves from Name: to Location:.

E: Selects a menu item. For example, pressing E here takes you to the IP configuration screen.

AS or z: Moves to next selection within a menu item. For example, pressing S moves from 100 Mbps to 10 Mbps.

Toggling between insert and overstrike mode

By default, the Console Manager is in overstrike mode, which means typing in a field replaces existing characters. Press cO to change to insert mode.
