Cisco Cisco Packet Data Interworking Function (PDIF)
secs can be an integer from 1 through 1000000.
reneg-limit num
Default: 5
Sets the number of allowed source violations within a detection period before forcing a PPP renegotiation. If
num is not specified, the value is set to the default.

num can be an integer from 1 through 1000000.
Usage Guidelines
This function allows the operator to configure a network to prevent problems such as when a user gets handed
back and forth between two PDSNs a number of times during a handoff scenario.
back and forth between two PDSNs a number of times during a handoff scenario.
When a subscriber packet is received with a source address violation, the system increments both the IP
source-violation reneg-limit and drop-limit counters and starts the timer for the IP-source violation period.
Every subsequent packet received with a bad source address during the IP-source violation period causes the
reneg-limit and drop-limit counters to increment.

Every subsequent packet received with a bad source address during the IP-source violation period causes the
reneg-limit and drop-limit counters to increment.
For example, if reneg-limit is set to 5, the system allows five packets with a bad source address (source
violations), but on the fifth packet, it re-negotiates PPP.

If the drop-limit is set to 10, the above process of receiving five source violations and renegotiating PPP occurs
only once. After the second 5-source violation, the call is dropped. The period timer continues to count
throughout this process.
only once. After the second 5-source violation, the call is dropped. The period timer continues to count
throughout this process.
If at any time before the call is dropped, the configured source-violation period is exceeded, the counters for
drop-limit is decremented by half and reneg-limit is decremented by 1. See period definition above.
drop-limit is decremented by half and reneg-limit is decremented by 1. See period definition above.
Examples
To set the maximum number of source violations before dropping a call to 100, enter the following command:
ip source-violation drop-limit 100
ip source-violation drop-limit 100
