Transceiver Diagnostics
The transceiver diagnostics test the integrity of the management bus transceivers used for
communication between the ASICs in the Inferno chipset and the CPU subsystem. (See
These diagnostics write test patterns to specific ASIC registers, read the registers, then compare results,
looking for errors in the communication path.
NOTE
The transceiver diagnostics are intended for modular "i" series switches only.
Usage Guidelines
These diagnostics were introduced with ExtremeWare Version 6.2.2b108. They operate as a non-invasive
background process under the umbrella of the system health check, and are disabled by default.
These diagnostics offer configurable threshold and window values that trigger system health check
actions when excessive hard failures are detected.
Related Commands
enable transceiver-test [all | slot <slot number> {backplane}]
enable transceiver-test [all | slot <slot number> | msm-a | msm-b]
disable transceiver-test
clear transceiver-test
configure transceiver-test failure-action [log | sys-health-check]
configure transceiver-test period <1-60>
configure transceiver-test threshold <1-8>
configure transceiver-test window <1-8>
unconfigure transceiver-test failure-action
unconfigure transceiver-test period
unconfigure transceiver-test threshold
unconfigure transceiver-test window
These commands are described in the sections that follow. The default settings are: disabled, log,
1 second, 3 errors in 8 windows.
Configuring the Transceiver Diagnostics
• To enable or disable the transceiver diagnostics on an Alpine system, use this command:
enable | disable transceiver-test [all | slot <slot number> {backplane}]]
• To enable or disable the transceiver diagnostics on a BlackDiamond system, use this command:
enable | disable transceiver-test [all | slot <slot number> | msm-a | msm-b]
• To configure how often the transceiver diagnostic test is run, use this command:
configure transceiver-test period <1-60>
where
specifies the delay, in seconds, between iterations of the test. The delay period is a
period
number in the range from 1 to 60 seconds. If you do not specify a value, the test uses the default of
1 second.
