CEE map & AMPP QoS profile in VCS

Hi all,

Could you please help me clarify the following?


VDX configuration referred:

1   (config)#cee-map default
2   (config-cee-map-default)#priority-table 1 1 1 0 1 1 1 15.0
3   (config-cee-map-default)#priority-group-table 0 weight 50 pfc on
4   (config-cee-map-default)#priority-group-table 1 weight 50 pfc off
5   (config-cee-map)#end

6   (config)#qos map cos-traffic-class vm1-cos2traffic-map 0 0 0 0 1 1 1 15.0

7   (config)#port-profile vm1-port-profile
8   (config-port-profile-vm1-port-profile)#qos-profile
9   (config-qos-profile)#cee default
10  (config-qos-profile)#qos cos 1
11  (config-qos-profile)#qos trust cos
12  (config-qos-profile)#qos cos-traffic-class vm1-cos2traffic-map
13  (config-qos-profile)#qos flowcontrol pfc 0 tx off rx off
14  (config-qos-profile)#qos flowcontrol pfc 1 tx off rx off
15  (config-qos-profile)#qos flowcontrol pfc 2 tx off rx off
16  (config-qos-profile)#qos flowcontrol pfc 3 tx off rx off
17  (config-qos-profile)#qos flowcontrol pfc 4 tx off rx off
18  (config-qos-profile)#qos flowcontrol pfc 5 tx on rx on
19  (config-qos-profile)#qos flowcontrol pfc 6 tx off rx off
20  (config-qos-profile)#qos flowcontrol pfc 7 tx off rx off

Q1:In the above configuration of AMPP QoS profile,
  do the commands "qos cos-traffic-class"(12) and "qos flow control"(13-20)
  overwrite the settings done by "priority-table"(2) and "priority-group-table"(3-4)
  commands in cee-map default global config?
Q2:If so,
   a)does it carry the weight configuration to qos profile from cee-map?
   b)should the configuration from line 12-20 be same for the qos profile of all the port profiles?
Q3Smiley Very Happyoes the pfc configuration in "priority-group-table"(3-4) apply to both tx and rx?
Q4Smiley Very Happyoes the "qos cos 1"(10) command apply default cos only to VMs associated

     (not to the switch interface)to this particular port profile?

Thanks
