The Exclusive Configuration Change Access feature (also called the “Configuration Lock” feature) allows you to have exclusive
change access to the Cisco IOS running configuration, preventing multiple users from making concurrent configuration changes.
The Access Session Locking addition to this feature extends the Exclusive Configuration Change Access feature such that
show and
debug commands entered by the user holding the configuration lock always have execution priority; show and
debug commands entered by other users are allowed to run only after the processes initiated by the configuration lock owner have
finished.
The Exclusive Configuration Change Access feature is complementary with the locking mechanism for the Configuration Replace
and Configuration Rollback feature (“rollback lock”).
The Configuration Lock feature feature was integrated into Release 12.0S, and the Access Session Locking feature extension
was implemented. The
configuration
mode
exclusive command was extended to include the following keyword options:
config_wait ,
expire ,
interleave ,
lock-show ,
retry_wait , and
terminate . The output of the
show
configuration
lock command was improved.
The extended feature was integrated into Releases 12.2(33)SRA, 12.4(11)T, 12.2(33)SXH, and 12.2(33)SB.
