Clarifications, Known Behaviors, and Resolved Issues
Diagnostics and Troubleshooting
OC12 Module Might Report False External Loopback Failure on External Test
When running normal or extended diagnostics on an OC12 module, the switch might incorrectly report
that the specified port fails when performing the external loopback diagnostic test (PD3-796908).
A3ci Running Normal Diagnostics Hangs in the "diag" State
Repeatedly running normal diagnostics on an A3ci hangs the switch in the diag state. For example,
running normal diagnostics on a module might generate the following error message on the console:
Double free or memory being overwritten.
sbmfree double (0/10629/1/0x84d9daf0/0x84d9db00)
(PD2-249307801)
NP Module Error Messages in the Log After Running Diagnostics
NP heartbeat and reboot error messages are shown in the log when running extended diagnostics on
NP based modules. The same error messages are also shown on the OC3 and ATM modules
(PD2-237117101).
Errors Not Displayed in show diagnostics Output
If you run extended diagnostics, diagnosed errors are recorded in the log, but are not shown in the
output of the
show diagnostics command (PD2-225483201).
Incorrect show diagnostics Output for BlackDiamond 6816
The output of the show diagnostics command displays BlackDiamond 6816 slots A, B, C, and D as 17,
18, 19, and 20 (PD2-106752601).
Entering q Does Not Quit Diagnostics Display
Entering q to quit the show diagnostics sys-health-check display does not quit the display
(PD2-145117543).
Single MSM Not Taken Offline
If you have only one MSM installed in a BlackDiamond chassis, you configure the system health check
alarm level to
card-down, and eight errors are detected, the MSM is not taken offline. The MSM remains
fully operational (PD2-143167301).
Automatic Memory Scanning Can Trigger Incorrect Reboot Loop Detection
On Summit and Alpine switches, if memory scanning is automatically initiated via the auto-recovery
parameter in the
configure sys-health-check command and the reboot loop detection threshold is 1,
the system might incorrectly detect a reboot loop and come up in minimal mode (PD2-140185601).
