2. Abstract
This document propose to add a comment to address the traffic class control problem in MBSS

3. Background Issue comes up from security sub-group discussion today
PTKSA replay counter and GTKSA replay counter fields are used to inform STAs how many replay counters to use for protecting data traffic
The number is determined by the number of traffic classes
In BSS, AP dictates the numbers
MBSS need to address the problem of controlling traffic classes
Solution options
Make it mesh-wide configuraiton
Negotiate in pairwise basis

4. Motion Add one comment to 11-09/0471r10 comment spreadsheet Comment:
mesh needs to figure out how to deal with traffic classes. Each needs a replay counter for protection. In infrastructure mode, it's dictated by AP. But in mesh, either need to define it as mesh-wide configuration, or let mesh STAs to negotiate in pairwise basis.
Recommended change:
The former makes more sense. Need submission to implement the former approach.
