Example for Configuring a TCP Test Instance

Networking Requirements

In Figure 1, an NQA TCP test needs to be performed to obtain the duration for setting up a TCP connection with SwitchC.

Figure 1 Networking diagram for configuring a TCP test instance

Configuration Roadmap

The configuration roadmap is as follows:

Configure SwitchA as an NQA client and configure SwitchC as an NQA server.
Configure the monitoring port number on the NQA server and create an NQA TCP test instance on the NQA client.

Procedure

Configure an IP address for each interface and ensure reachable routes between switches.

# Configure SwitchA.

<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan 100
[SwitchA-vlan100] quit
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type hybrid
[SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 100
[SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 100
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] ip address 10.1.1.1 24
[SwitchA-Vlanif100] quit
[SwitchA] ip route-static 10.2.1.0 255.255.255.0 10.1.1.2

# Configure SwitchB.

<HUAWEI> system-view
[HUAWEI] sysname SwitchB
[SwitchB] vlan 100
[SwitchB-vlan100] quit
[SwitchB] vlan 110
[SwitchB-vlan110] quit
[SwitchB] interface gigabitethernet 0/0/1
[SwitchB-GigabitEthernet0/0/1] port link-type hybrid
[SwitchB-GigabitEthernet0/0/1] port hybrid pvid vlan 100
[SwitchB-GigabitEthernet0/0/1] port hybrid untagged vlan 100
[SwitchB-GigabitEthernet0/0/1] quit
[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] ip address 10.1.1.2 24
[SwitchB-Vlanif100] quit
[SwitchB] interface gigabitethernet 0/0/2
[SwitchB-GigabitEthernet0/0/2] port link-type hybrid
[SwitchB-GigabitEthernet0/0/2] port hybrid pvid vlan 110
[SwitchB-GigabitEthernet0/0/2] port hybrid untagged vlan 110
[SwitchB-GigabitEthernet0/0/2] quit
[SwitchB] interface vlanif 110
[SwitchB-Vlanif110] ip address 10.2.1.1 24
[SwitchB-Vlanif110] quit

# Configure SwitchC.

<HUAWEI> system-view
[HUAWEI] sysname SwitchC
[SwitchC] vlan 110
[SwitchC-vlan110] quit
[SwitchC] interface gigabitethernet 0/0/1
[SwitchC-GigabitEthernet0/0/1] port link-type hybrid
[SwitchC-GigabitEthernet0/0/1] port hybrid pvid vlan 110
[SwitchC-GigabitEthernet0/0/1] port hybrid untagged vlan 110
[SwitchC-GigabitEthernet0/0/1] quit
[SwitchC] interface vlanif 110
[SwitchC-Vlanif110] ip address 10.2.1.2 24
[SwitchC-Vlanif110] quit
[SwitchC] ip route-static 10.1.1.0 255.255.255.0 10.2.1.1

Configure an NQA server on SwitchC.
# Configure the IP address and port number for monitoring TCP connections on the NQA server.
```
[SwitchC] nqa-server tcpconnect 10.2.1.2 9000
```

Configure the NQA client on SwitchA.

# Enable the NQA client and create a TCP test instance.

[SwitchA] nqa test-instance admin tcp
[SwitchA-nqa-admin-tcp] test-type tcp
[SwitchA-nqa-admin-tcp] destination-address ipv4 10.2.1.2
[SwitchA-nqa-admin-tcp] destination-port 9000

Start the test instance.
```
[SwitchA-nqa-admin-tcp] start now
```

Check the configuration.

# Check NQA test results on SwitchA.

[SwitchA-nqa-admin-tcp] display nqa results test-instance admin tcp

 NQA entry(admin, tcp) :testflag is inactive ,testtype is tcp
