HP Network Direr Software Products manual There Is No General Unit Information For My Device

270CHAPTER 6: VIEWING DEVICE DETAILS

It is also possible that the SNMP requests that 3Com Network Director uses to communicate with the device timed out. If this is the case then the Discovery report will indicate that this problem occurred during discovery. For more information on this report see “The Discovery Report”on page 131 and for details of how to increase the retry and timeout values for a device see “Using 3Com Network Director On A Multi-Site Network” on page 681.

There Is No General Unit Information For My Device

The Properties dialog box for the device you selected shows a tree on the left-hand side, but no unit is listed in the tree, so you cannot view the General tab for that unit.

In a case where the device consists of a single unit, the general properties of that unit can be viewed from the Unit tab for the device.

A Lot of Fields in the Properties Dialog Box Show Unknown

Many of the fields displayed in the Properties dialog box show Unknown.

There are several reasons why this happens:

■The device you selected is not fully supported by 3Com Network Director: If the device is not fully supported by 3Com Network Director the necessary information cannot be collected. For these fields, 3Com Network Director shows Unknown. Ensure that the device is fully supported by 3Com Network Director.

■The network map you are using was discovered using 3Com Network Supervisor®: If the network map was discovered using 3Com Network Supervisor®, some of the information displayed in the Properties dialog box is missing, so some fields show Unknown. Re-discover your network using 3Com Network Director.

■The SNMP requests used by 3Com Network Director to discover the device timed out. If this is the case then the Discovery report will indicate that this problem occurred during discovery. For more information on this report see “The Discovery Report” on page 131 and for details of how to increase the retry and timeout values for a device see “Using 3Com Network Director On A Multi-Site Network” on page 681.
