When a packet filter is created with an order greater than 32767, attempts to delete this filter will fail. Error messages can be seen in /var/log/tmm* when a packet filter object is deleted (or possibly created).
Unknown (inexplicable) impact on traffic: - Packet filters that have been deleted may continue to exist in TMM - Older versions of rules (that have been deleted/recreated) may continue to be applied to traffic
Packet filter rules with an order between 32768 and 65535 (inclusive).
- To prevent this condition from occurring in the first place, restrict packet filter 'order' to 1-32767 (inclusive). - To remove the phantom/incorrect packet filter rules from the packet path (TMM), restart TMM ("bigstart restart tmm", which may need to run on each blade of a chassis system).
Ensured that packet filters with orders greater than 32767 are able to be deleted.
