backplaneTest

Tests the backplane connection for a multiple-blade configured system.

Synopsis backplanetest [--slot number][-passcnt count][-payload value][-pat type][-ports itemlist]

[-verbose mode]

Description Use this command to verify the backplane connection for each blade through the backend external

(BE) ports. This command can run only on a multiple-blade configured system. It assumes that all

blades available on the specified switch have passed the blade diagnostics tests. This command

verifies the backplane connection by using a functional blade's frame transmitter and receiver

features.

No other diagnostics can be executed until this test is completed.

This command is supported only on Brocade 24000 platforms.

The execution of this command is subject to Admin Domain restrictions that may be in place.

Operands This command has the following optional operands:

--slot number Specifies the slot on which the diagnostic operates. The ports specified are

relative to this slot number.

-passcnt count Specifies the number of times to perform this test. The default value is 1.

-payload value Specifies the byte size of the test frame payload. The payload size must be in

multiples of 4, and the minimum size is 16. The default value is 512 bytes.

-pat type Specifies the test-pattern type to use in the test frame payload. Twenty types

of predefined patterns are provided with the test; the default is jCRPAT

(type=17). Use dataTypeShow to display the pattern types supported with

backplaneTest.

-ports itemlist Specifies a list of blade ports to test. By default, all the blade ports in the

specified slot are used. Refer to itemList for further details.

-verbose mode Specifies verbose mode. If specified with a nonzero value, this mode displays

the test progress in detail. The default value is to disable the mode.

Examples To test backplane connections on a Brocade director:

switch:admin> backplanetest -ports 1/16, 18, 20 -payload 2048 -verbose 1
