Configuring an HTTP Test

Procedure

1. Access the system view.

   system-view

2. Create an NQA test instance and access the test instance view.

   nqa test-instance admin-name test-name

3. Set the test type to HTTP.

   test-type http

4. Set the destination address.

   The destination address in the HTTP test can be in the IP address format or URL format.

   • Run the destination-address ipv4 ip-address command to configure the destination IP address.
   • Run the destination-address url url-string command to configure the destination URL.
     

     When the destination address is in the URL format, enable the dynamic domain name resolution function (using the dns resolve command) and the DNS server (using the dns server command). Otherwise, the test fails.
5. Set the HTTP operation type to Get.

   http-operation get

6. Optional: Configure other parameters for the HTTP test.

   Item	Command	Description
   Configuring description of a test instance	description description-information	-
   Configuring a tested VPN instance	vpn-instance vpn-instance-name	-
   Setting the outbound interface for sending the test packet	source-interface [ interface-type interface-number ]	By default, the FW determines the outbound interface by querying the routing table. If there are multiple paths to the tested destination address, you can specify the source interface, so that test packets are forwarded along a specified path.
   Setting the source IP address of test packets	source-address ipv4 ip-address	By default, no source IP address is specified for test packets. The packets use the primary IP address of the outbound interface as their source IP address. The specified source IP address must be the IP address of an Up interface on the FW. Otherwise, the test will fail.
   Setting the source port of test packets	source-port port-number	-
   Setting the destination port of test packets	destination-port port-number	By default, the destination port of the test packet in the HTTP test is set to 80.
   Configuring the relative URL and HTTP version	http-url dest-url [ v1.0 | v1.1 ]	By default, if the resource relative URL is not configured, you can request for access the root directory of the HTTP server. By default, the HTTP version is v1.0.
   Setting the TTL value of test packets	ttl value	The default value is 30.
   Setting the ToS value of test packets	tos value	The default value is 0.
   Configuring the number of probes in a single test (one probe is used to obtain an HTTP server page)	probe-count number	By default, one test initiates three probes.
   Setting the test interval	frequency interval	By default, no test interval is set, and the test runs only once.
   Setting the probe failure percentage	fail-percent percent	By default, the test failure percentage is 100%. That is, the test is considered failed only when all probes fail.
   Setting the timeout for a single probe	timeout time	By default, the expiration time for a single probe in the HTTP test is 3s.
   Setting the maximum number of historical records	records history number	By default, there are a maximum of 50 historical records.
   Configuring the maximum number of test result records	records result number	By default, a maximum of five test results are recorded.
   Setting the aging time of a test instance	agetime hh:mm:ss	By default, the aging time of the test instance is set to 0, that is, never aging.
   Configuring the system to send test packets without querying the routing table	sendpacket passroute	By default, the FW forwards the test packets based on the route queried in the routing table.

7. Start the NQA test.

   start

   Select one of the following start modes as required.

   • Start the NQA test immediately.

     start now [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } ]

   • Start the NQA test at a specified time point.

     start at [ yyyy/mm/dd ] hh:mm:ss [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } ]

   • Start the NQA test after the delay of a specified period.

     start delay { seconds second | hh:mm:ss } [ end { at [ yyyy/mm/dd ] hh:mm:ss | delay { seconds second | hh:mm:ss } | lifetime { seconds second | hh:mm:ss } ]
