58 Advanced System Diagnostics and Troubleshooting Guide
Diagnostics
BlackDiamond systems—whether the module type being tested is an MSM or an I/O module), but
adds the following two test sets:
—
Packet memory test (where possible, this test also attempts to remap up to eight errors)
— Additional loop-back tests: Big packet (4k) MAC, transceiver, VLAN
• On Demand Packet Memory Scan —The packet memory test scans the switch fabric in the switch
(Summit or Alpine) or the module in the specified slot (BlackDiamond only) for single-bit packet
memory defects.
While the packet memory scan is normally invoked and runs as part of the extended system
diagnostics, it can also be run independently to identify and correct errors in the packet memory
area.
The packet memory scan diagnostic scans the specified module (in a BlackDiamond switch), the
passive backplane of an Alpine switch, or the switch fabric in a Summit switch to detect single-bit
memory defects and their associated buffer locations.
Related Commands
run diagnostics normal slot [msm-a | msm-b | <slot number>]
run diagnostics_noslot [normal | extended | packet-memory] (Alpine and Summit only)
configure diagnostics [extended | fastpost | normal | off]
show diagnostics {slot [msm-a | msm-b | <slot number>]}
show diagnostics packet-memory slot <slot number>
Running the Diagnostics on BlackDiamond Systems
These runtime diagnostics can be run on specific slots in a BlackDiamond switch. These tests check the
CPU subsystem, the switch fabric subsystem (MSMs and I/O modules), and control and data path
communication.
To run the diagnostics on a BlackDiamond system, use this command:
run diagnostics [extended | normal | packet-memory] slot [<slot-number> |
msm-a | msm-b]
where:
The command is only executed on one module at a time, but you can queue up two
run diagnostics
commands at a time.
Runtime Diagnostics on “ i” Series Alpine and Summit Systems
To run the diagnostics on an Alpine or a Summit system, use this command:
run diagnostics_noslot [normal | extended | packet-memory]
extended
Runs the extended diagnostic routine.
normal
Runs the normal diagnostic routine.
packet-memory
Runs packet memory diagnostics.
slot number
Specifies an I/O module installed in a particular slot of a BlackDiamond chassis.
msm-a
Specifies the MSM installed in slot A of a BlackDiamond chassis.
msm-b
Specifies the MSM installed in slot B of a BlackDiamond chassis.
