Private Network for Validator Nodes for Sawtooth

Below are the validators

On Terminal 0 I started Validato 0,Rest API 0, settings-tp 0  and identity tp0 
1.sudo sawtooth-validator -vv   --bind network:tcp://10.34.14.1:8800   --bind component:tcp://10.34.14.1:4004   --peering dynamic   --endpoint tcp://10.34.14.1:8800   --scheduler serial   --network-auth challenge
2.settings-tp -C tcp://10.34.14.1:4004
3.identity-tp -C tcp://10.34.14.1:4004
4.sawtooth-rest-api -C tcp://10.34.14.1:4004 -B 10.34.14.1:8008

I also registered a valida user for settings as below for user dev.
$sawset proposal create sawtooth.identity.allowed_keys=02a8d5d019a596e979e073dedd559ab23e4982f35d79292e50b94e2aa8e2f5d626 --url http://10.34.14.1:8008
$ sudo sawtooth identity policy create policy_sandip "PERMIT_KEY 03a16e1d0dc29ba97a6af90679b3ce7ba0fd452bd1210f8fa02d46f5b4f92526c1" --url http://10.34.14.1:8008 -k ~/.sawtooth/keys/dev.priv 
Policy committed in 0.142006 sec
$sudo sawtooth identity role create network policy_sandip -k /home/dev/.sawtooth/keys/dev.priv --url http://10.34.14.1:8008
Role committed in 0.136423 sec
$ sudo sawtooth identity role create transactor policy_sandip -k /home/dev/.sawtooth/keys/dev.priv --url http://10.34.14.1:8008
Role committed in 0.134269 sec
$ sawtooth identity role list --url http://10.34.14.1:8008
network: policy_sandip
transactor: policy_sandip

then I started validator,settings,identity and rest api on other node as  another ubuntu machine whose validator pub key is 03a16e1d0dc29ba97a6af90679b3ce7ba0fd452bd1210f8fa02d46f5b4f92526c1

$sudo sawtooth-validator -v     --bind network:tcp://10.34.15.58:8800     --bind component:tcp://10.34.15.58:4004     --peering dynamic     --endpoint tcp://10.34.15.58:8800     --seeds tcp://10.34.14.1:8800    --scheduler serial     --network-auth challenge

Any example with more than one PERMIT_KEY?
The key that you permit is the validator key?
