How to configure the TWAMP server

To use the TWAMP server on a Vyatta router, you must first configure the TWAMP service.

Note: To start the steps in this task, first enter configuration mode.

Start the TWAMP server. By default, the server accepts any connection request from any client.
```
vyatta@R1# set service twamp server
```
Add a client to the list of clients that can connect to the TWAMP server in the unauthenticated mode.
```
vyatta@R1# set service twamp server client-list 11.0.0.0/8
```
This adds the client that has IP address 11.0.0.0/8.
Specify the base-10 value of the DSCP byte in the IP header of control packets sent from the server.
```
vyatta@R1# set service twamp server dscp-value 34
```
This specifies a value of 34.
Specify the maximum number of control sessions for each TWAMP server.
```
vyatta@R1# set service twamp server maximum-connections 10
```
This specifies a maximum of 10 control sessions.
Limit the number of maximum number of test sessions for each control session.
```
vyatta@R1# set service twamp server maximum-sessions-per-connection 16
```
This sets the limit to 16.

Disable the mixed client authentication mode.

vyatta@R1# set service twamp server mode no-mixed

Specify the TCP port to use for control sessions.
```
vyatta@R1# set service twamp server port 862
```
This sets the TCP port to 862.
Set the timeout value for control session inactivity.
```
vyatta@R1# set service twamp server server-inactivity-timeout 5
```
This sets the timeout to 5 seconds.
Set the timeout value for test session inactivity.
```
vyatta@R1# set service twamp server test-inactivity-timeout 10
```
This sets the timeout to 10 seconds.
Create a test user account and assign a password to it.
```
vyatta@R1# set service twamp server user test password pass1
```
This sets a user account named test with the password pass1.
Commit the configuration.
```
vyatta@R1# commit
```
Exit the configuration mode.
```
vyatta@R1# exit
```

Optional: Show the status of the server.

vyatta@R1:~$ show service twamp server status

TWAMP Server is configured and is running.

Optional: Show TWAMP server session activity.

vyatta@R1:~$ show service twamp server sessions all
