Lock CONFIGURATION Mode

Dell EMC Networking OS allows multiple users to make congurations at the same time. You can lock CONFIGURATION mode so that only

one user can be in CONFIGURATION mode at any time (Message 2).

You can set two types of lockst: auto and manual.

• Set auto-lock using the configuration mode exclusive auto command from CONFIGURATION mode. When you set auto-

lock, every time a user is in CONFIGURATION mode, all other users are denied access. This means that you can exit to EXEC Privilege

mode, and re-enter CONFIGURATION mode without having to set the lock again.

• Set manual lock using the configure terminal lock command from CONFIGURATION mode. When you congure a manual

lock, which is the default, you must enter this command each time you want to enter CONFIGURATION mode and deny access to

others.

Viewing the Conguration Lock Status

If you attempt to enter CONFIGURATION mode when another user has locked it, you may view which user has control of

CONFIGURATION mode using the show configuration lock command from EXEC Privilege mode.

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

DellEMC(conf)#configuration mode exclusive auto

BATMAN(conf)#exit

3d23h35m: %RPM0-P:CP %SYS-5-CONFIG_I: Configured from console by console

DellEMC#config

! Locks configuration mode exclusively.

DellEMC(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 congure 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 congured the lock.

NOTE: If your session times out and you return to EXEC mode, the CONFIGURATION mode lock is uncongured.

LPC Bus Quality Degradation

LPC Bus Quality Analyzer (LBQA) runs on the system that make use of the LPC bus. It constantly monitors the LPC bus and alerts or

warns the user using following methods when it detects signal degradation:

1 The system displays a high priority syslog message. The text of this syslog is CPU Clock signal has degraded below

acceptable threshold on stack-unit <stack-unit-number> with service tag <service tag>. Please
