I found decision for my problem.

First I looked session and  i had seen interface "Virtual-Access".

show subscriber session username 682
Type: PPPoE, UID: 432, State: authen, Identity: 682
IPv4 Address: 10.200.1.179
Session Up-time: 1w3d    , Last Changed: 00:02:50
Interface: Virtual-Access1.791
Switch-ID: 4046735

after I sent coa with next contain:

echo 
"User-Name=\"10.200.1.179\",Cisco-Account-Info=\"S10.200.1.179\",cisco-avpair+=\"interface-template-name=Virtual-Access1.791\",cisco-avpair+=\"lcp:interface-config=ip \
 flow monitor flow_v5_carbon 
input\",cisco-avpair+=\"lcp:interface-config=ip flow monitor 
flow_v5_carbon output\"" | radclient -c 1 -r 1 -t 1 -x 172.31.1.33:3799 
coa MyPass
Sending CoA-Request of id 129 to 172.31.1.33 port 3799
     User-Name = "10.200.1.179"
     Cisco-Account-Info = "S10.200.1.179"
     Cisco-AVPair += "interface-template-name=Virtual-Access1.791"
     Cisco-AVPair += "lcp:interface-config=ip flow monitor 
flow_v5_carbon input"
     Cisco-AVPair += "lcp:interface-config=ip flow monitor 
flow_v5_carbon output"
rad_recv: CoA-ACK packet from host 172.31.1.33:3799, id=129, length=70
     Cisco-Account-Info = "S10.200.1.179"
     Cisco-Account-Info = "$IVirtual-Access1.791"


It is work!

sho flow interface
...
Interface Virtual-Access1.791
   FNF:  monitor:          flow_v5_carbon
         direction:        Input
         traffic(ip):      on
   FNF:  monitor:          flow_v5_carbon
         direction:        Output
         traffic(ip):      on
