if packets are fragmented, even the port matches rrdag setting, it will be disaggregated based on default dag. Form example, if SIP traffic is coming from a single source and destination port 5060, all the packets are redirected to a single tmm though it has rrdag enabled with port range set to 5060 in rrdag setting.
Performance may be degraded as the fragmented packets distribution may not optimal and may load few tmms heavily.
Always with fragmented packets even after rrdag enabled with correct port range setting
No work around or mitigation except upgrading to a release with this fix.
Proper rrdag selection values are propagated to the platform.
