Using the SEHI100TX Hub View

Device Configuration

This polling interval controls how often a survey is conducted of the devices installed in your SEHI100TX-controlled HUBStack.

Port Operational State

This polling interval controls the update of the information displayed in the Port Status boxes for each port in the device. Port state information includes link state (the color code) and admin state (on or off).

Statistics

This polling interval controls how often the information displayed in the Port Status boxes is updated when the Port Display Form is set to a rate or percentage, and how often the Device, Module, and Port statistics counts are updated.

NOTE

SPMA generates network trafÞc when it retrieves the above-described information; keep in mind that shorter intervals mean increased network trafÞc. Range limits for these polling times are 0-999,999 seconds; however, an entry of 0 will be treated as a 1.

Enabling/Disabling Ports

!

CAUTION

You can enable and disable ports both from the Module menu, which affects all ports on a single module, or device; or from the Port menu, which affects individual ports.

To enable or disable an individual port:

1. Click mouse button 1 on the Port Status box to toggle the port On or Off.

or

1.Click mouse button 3 on the Port Index or Port Status box to display the Port menu.

2.Drag down to Enable or Disable, as appropriate, and release. The selected port changes color when its state changes. A disabled port is blue.

To enable or disable all ports in a module:

1.Click mouse button 3 on the Module Index box to open the Module menu.

2.Drag down to Enable All Ports or Disable All Ports, as appropriate, and release.

When disabling all ports on a module, make sure you donÕt disable the port through which your management station is communicating with the HUBStack, or you will lose contact with the stack.
