Setup Guide

Lock CONFIGURATION Mode

The system 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 locks: 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.

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.

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

Dell(conf)#configuration mode exclusive auto

BATMAN(conf)#exit

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

Dell#config

! Locks configuration mode exclusively.

Dell(conf)#

Message 1: Conguration mode Locked Error

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

Message 2 Cannot Lock CONFIGURATION mode Error

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 )

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
