Information About UDP Lite
The UDP Lite Support feature, which is an enhancement to the existing IPv6 functionality, supports the UDP Lite protocol.
This feature is only applicable to the IPv6 addresses of the controller and APs. IPv6 mandates complete payload checksum for UDP. The UDP Lite Support feature minimises the performance impact on the controller and AP by restricting the checksum calculation coverage for the UDP Lite header to 8 bytes only.
The use of the UDP Lite Support feature impacts intermediate firewalls to allow UDP Lite protocol (protocol ID of 136) packets. Existing firewalls might not provide the option to open specific ports on UDP Lite protocol. In such cases, the administrator must open up all the ports on UDP Lite.
Restrictions for UDP Lite Support
Mobility IPv6 tunnels do not support the UDP Lite Support feature.
