DETAILED STEPS
Configuring IPSec Security Association Idle Timers
To configure the IPSec Security Association Idle Timers feature, you must understand the following
concepts and tasks:
• Lifetimes for IPSec Security Associations, page SC-121
• IPSec Security Association Idle Timers, page SC-121
• Configuring the IPSec SA Idle Timer Globally, page SC-121
• Configuring the IPSec SA Idle Timer for Each Crypto Profile, page SC-122
Command or Action Purpose
Step 1
configure
Example:
RP/0/0/CPU0:router# configure
Enters global configuration mode.
Step 2
crypto nat-transparency disable
Example:
RP/0/0/CPU0:router(config)# crypto ipsec
nat-transparency disable
Disables the NAT transparency capability.
Step 3
end
or
commit
Example:
RP/0/0/CPU0:router(config)# end
or
RP/0/0/CPU0:router(config)# commit
Saves configuration changes.
• When you issue the end command, the system
prompts you to commit changes:
Uncommitted changes found, commit them
before exiting(yes/no/cancel)?
[cancel]:
– Entering yes saves configuration changes to
the running configuration file, exits the
configuration session, and returns the
router to EXEC mode.
– Entering no exits the configuration session
and returns the router to EXEC mode
without committing the configuration
changes.
– Entering cancel leaves the router in the
current configuration session without
exiting or committing the configuration
changes.
• Use the commit command to save the
configuration changes to the running
configuration file and remain within the
configuration session.
