Lpc Bus Quality Degradation - Dell S6100 Configuration Manual

You can then send any user a message using the send command from EXEC Privilege mode. Alternatively, you can clear any line using the
clear command from EXEC Privilege mode. If you clear a console session, the user is returned to EXEC mode.
Example of Locking CONFIGURATION Mode for Single-User Access
Dell(conf)#configuration mode exclusive auto
BATMAN(conf)#exit
3d23h35m: %RPM0-P:CP %SYS-5-CONFIG_I: Configured from console by console
Dell#config
! Locks configuration mode exclusively.
Dell(conf)#
If another user attempts to enter CONFIGURATION mode while a lock is in place, the following appears on their terminal (message 1): %
Error: User "" on line console0 is in exclusive configuration mode.
If any user is already in CONFIGURATION mode when while a lock is in place, the following appears on their terminal (message 2): %
Error: Can't lock configuration mode exclusively since the following users are currently
configuring the system: User "admin" on line vty1 ( 10.1.1.1 ).
NOTE: The CONFIGURATION mode lock corresponds to a VTY session, not a user. Therefore, if you configure a lock and then
exit CONFIGURATION mode, and another user enters CONFIGURATION mode, when you attempt to re-enter CONFIGURATION
mode, you are denied access even though you are the one that configured the lock.
NOTE: If your session times out and you return to EXEC mode, the CONFIGURATION mode lock is
unconfigured.

LPC Bus Quality Degradation

LPC Bus Quality Analyzer (LBQA) will run on Intel C2000 (Rangeley family) based platforms that make use of the LPC bus. The canary
code that runs along with the pollers will constantly monitor the LPC bus and once it detects signal degradation, it ,alerts or warns the user
via following methods:
1 A high priority syslog is issued. The text of this syslog in TOR platforms would be "CPU Clock signal has degraded below acceptable
threshold on stack-unit <stack-unit-number> with service tag <service tag>. Please contact Technical Support". In chassis platforms
the text would be "CPU Clock signal has degraded below acceptable threshold on Line card <line card number> with service tag
<service tag>. Please contact Technical Support". This syslog continues to be emitted every 30 minutes. An SNMP trap with this
information will also be generated once every hour.
2 If SupportAssist is enabled - it sends the event message to the global SupportAssist server immediately and there after once in two
days, so Dell can assist in pro-actively notifying and assisting customers when this condition is hit.
3 System Status LED changes to an alarm state, blinking amber for S3048–ON, S6100–ON and Z9100–ON, and solid amber for C9000.
It is not possible to suppress this LED pattern until the unit is switched off (for RMA).
4 The switch (control/management/data plane) continues to be active.
NOTE: This is true even if the unit in question is the master (in a HA chassis environment – as in the case of RPM) or a
Stack master or standby (as in case of S3048-ON).
A new CLI command has been introduced to disable / re-enable this feature. The details are given below:
