Configuring the TCP template
A feature that uses the TCP template performs the TCP operation to test whether the NQA client can establish a TCP connection to a specific port on the server.
In TCP template view, you can specify the expected data to be returned. If you do not specify the expected data, the TCP operation tests only whether the client can establish a TCP connection to the server.
The TCP operation requires both the NQA server and the NQA client. Before you perform a TCP operation, configure a TCP listening service on the NQA server. For more information about the TCP listening service configuration, see "Configuring the NQA server."
To configure the TCP template:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a TCP template and enter its view. | nqa template tcp name | By default, no TCP templates exist. |
3. (Optional.) Specify the destination IP address of the operation. |
| By default, no destination address is specified. The destination address must be the same as the IP address of the listening service configured on the NQA server. |
4. (Optional.) Specify the destination port number for the operation. | destination port port-number | By default, no destination port number is specified. The destination port number must be the same as the port number of the listening service on the NQA server. |
5. (Optional.) Specify the payload fill string for requests. | data-fill string | The default payload fill string is the hexadecimal string 00010203040506070809. |
6. (Optional.) Specify the source IP address for the probe packets. |
| By default, the packets take the primary IP address of the output interface as their source IP address. The source IP address must be the IP address of a local interface, and the interface must be up. Otherwise, no probe packets can be sent out. |
7. (Optional.) Configure the expected data. | expect data expression [ offset number ] | By default, no expected data is configured. The NQA client performs expect data check only when you configure both the data-fill and expect-data commands. |
