Before you start a configuration session, you might want to check to see if there are other configuration
sessions in progress. More than one user can open a target configuration session at a time, allowing
multiple users to work on separate target configurations.

The procedure for viewing the active configuration sessions depends on the type of configuration
session. For administration configuration sessions, which assign hardware components in SDRs and
multishelf systems, you must be in administration EXEC mode to view the active administration
configuration sessions. For SDR configuration sessions, you must be in EXEC mode to view the active
SDR configuration sessions.

To view the active administration configuration sessions, connect to the DSC and enter the show
configuration sessions command in administration EXEC mode, as shown in the following example:

RP/0/RP0/CPU0:CRS-8_P1# admin

RP/0/RP0/CPU0:CRS-8_P1(admin)# show configuration sessions

Session Line User Date Lock

To view the active SDR configuration sessions, connect to the appropriate SDR and enter the show
configuration sessions command in EXEC mode, as shown in the following example:

RP/0/RP0/CPU0:router# show configuration sessions

Session Line User Date Lock

00000201-002180dd-00000000 vty0 test Thu Mar 16 13:16:17 2006

00000201-001b307a-00000000 vty2 cisco Thu Mar 16 13:16:17 2006 *

If an asterisk (*) appears in the Lock column, the user is using an exclusive configuration session and
you cannot start a configuration session until the exclusive configuration session is closed. For more
information, see the

“Starting an Exclusive Configuration Session” section on page 4-26

Note

Configuration sessions for the administration configuration and each SDR are managed independently.
For example, if a user locks the administration configuration, you can still configure an SDR if other
users have not locked a configuration session for that SDR.
