Cisco Wireless LAN Controller IPv6 Deployment Guide, CUWN Release 8.0

Phase 1—Client IPv6 Support in WLC Release 7.2 to 7.6

Each RA Throttling option is described below:



Throttle Period: The period of time that throttling takes place. RA throttling takes effect only after the “Max Through” 
limit is reached for the VLAN.



Max Through: This is the maximum number of Router Advertisements on the VLAN before throttling kicks in. The “No 
Limit” option allows an unlimited amount of RAs through with no throttling.



Interval Option: The interval option allows the controller to act differently based on the RFC 3775 value set in the IPv6 
RA.

Passthrough – This value allows any RAs with an RFC3775 interval option to go through without throttling.

Ignore – This value will cause the RA throttler to treat packets with the interval option to be treated as a regular 
RA and subject to throttling if in effect.

Throttle – This value will cause the RAs with the interval option to always be subject to rate limiting.



Allow At-least: The minimum number of Router Advertisements per router that will be sent as multicast before 
throttling takes effect.



Allow At-most: The maximum number of Router Advertisements per router that will be sent as multicast before 
throttling takes effect. The “No Limit” option will allow an unlimited amount of RAs through for that router.

The numerical values of the Allow At-least option must be less than the Allow At-most option which should be less than 
Max Through option.
