You can test the Omni Switch/Router 

Multi VBUS

 (

MVBUS

) backplane and the frame fabric 

ASIC

 of every switching module with the 

 command. The syntax for this command is 

as follows:

The 

 option lets you set the number of times to run the test, which can be from 

0 to 999. If you enter 

, the 

 test will continue indefinitely. If you do not use the 

 option, then the 

 test will be executed once.

Using the 

 option requires the use of external cables or wrap plugs for the first 

physical port of every switching module in the chassis. The external cables or wrap plugs 
used in this test are identical to the one listed in the full duplex port test. See Omni 
Switch/Router Port Test Wrap Cable/Plug Requirements on page 36-10 for more information.

The 

 option, which can be used with the 

 option, performs an internal loop-

back. Using this option performs the 

 test without the use of external cables or wrap 

plugs.

The chassis should be fully loaded (i.e., Omni Switch/Router modules in all slots) to achieve a 
thorough testing of both the frame fabric 

ASICs

 and the Omni Switch/Router backplane. In 

addition, an 

MPX

 should be installed in Slot 1.

To execute the framefab test indefinitely, for example, enter

at the system prompt. A screen similar to the following will be displayed.
