Packets may be redirected to the wrong TMM. Such redirections are indicated by a non-zero count in the 'packets' column of the 'tmctl -d blade tmm/flow_redir_stats' command, as in the below example: tmctl -d blade tmm/flow_redir_stats pg pu redirect_pg redirect_pu packets -- -- ----------- ----------- ------- 0 1 0 0 11


Performance may be impacted as packets are redirected to the correct TMM.


This may occur on VIPRION B4300 blades in VIPRION C4800 (8-slot) chassis.
