ip inactivity-timer
ip re-authenticate-auto-detect ip-subscriber
ip route-map ip-subscriber
host1(config-if)#ip destination-prefix 10.0.0.0 255.0.0.0
Use the no version to remove the association between the interface and the
specified IP destination address and mask.
See ip destination-prefix
Use to configure the inactivity timer value for an IP interface.
A dynamically created subscriber interface is deleted if it is inactive for a period
longer than the inactivity timer value. IP polls the dynamic interface at the
configured interval to determine whether the interface was active during the
interval. Inactive interfaces are deleted only when the period of inactivity is equal
to or greater than the configured value.
For example, if you configure an inactivity timer of 15 minutes, IP polls the
interface every 15 minutes. If a poll determines that the interface was last active
14 minutes earlier, the inactive time is less than the configured value so nothing
happens. IP polls again 15 minutes later. If the interface is still inactive then the
total period of inactivity is now 29 minutes. This is greater than the configured
value and the interface is deleted.
On static interfaces, the subscriber's access route is removed when the inactivity
timer is exceeded. When the subscriber logs back in, the timer is restarted.
The timer value can in the range 0–65335 minutes. A timer value of 0 specifies
that dynamically created subscriber interfaces are never deleted by the inactivity
timer.
Example
host1(config-if)#ip inactivity-timer 100
Use the no version to restore the default, in which inactivity timer feature is
disabled.
See ip inactivity-timer
Use to re-authenticate the auto-detected subscribers or Dynamic Subscriber
Interfaces (DSIs) created on static and dynamic primary IP interfaces, using the
DHCP options when the DHCP external application manages the DSIs following
a cold boot. The no version negates the command or restores the defaults.
You can issue this command from Interface Configuration mode or Profile
Configuration mode.
Example
host1(config-if)#ip re-authenticate-auto-detect ip-subscriber
Use the no version negate the command or restore the defaults.
