#s5352c-ei

Question 1: What are common reasons why an OSPF neighbor relationship cannot change to full state on Huawei switch? I use the switch S5352C-EI and S2700-9TP-SI-AC most time on network time.

  Answer 1: Common causes of this problems are:

1 The OSPF network is a non-broadcast multiple access (NBMA) network, and no neighbor

is configured.

2 The interval at which the OSPF neighbor sends Hello packets is longer than the aging time

of the neighbor relationship.

3 In a stub area or not-so-stubby area (NSSA) area, some devices are not configured as stub

routers or NSSA routers.

4 The configuration of OSPF verification is incorrect.

5 The OSPF router IDs on two ends of the OSPF link are different.

6 The network types on two ends of the OSPF link are different.

7 The MTU values on two ends of the OSPF link are different.

8 OSPF is not enabled on the local or remote device.

9 The area numbers on two ends of the OSPF link are different.

  Question 2: Why do static routes imported to OSPF fail to take effect?

How to Configure an HTTP Test Instance on Huawei Switch

Context

Before configuring an HTTP test instance, configure an HTTP server and ensure reachable routes between the HTTP client and the HTTP server.

Through an NQA HTTP test, you can obtain the response speed in three phases:

  DNS resolution time: indicates the time taken to resolve the HTTP server domain name into its IP address. During this process, the NQA client sends a DNS request to the DNS server. The DNS server resolves the domain name of the HTTP server to an IP address and returns a DNS response.

  TCP connection setup time: indicates the time spent in setting up a TCP connection between the NQA client and the HTTP server through three-way handshake.

  Transaction time: indicates a period from the time the client sends a Get packet to the HTTP server to the time a response packet sent by the client reaches the HTTP server.

The NQA client also functions as the HTTP client. Perform the following steps on the NQA client.

  The configuration overview, taking the switch S5352C-EI and S2700-9TP-SI-AC for the example.

Step 1 Run:

system-view

The system view is displayed.

  Step 2 Run:

nqa test-instance admin-name test-name

An NQA test instance is created, and the NQA view is displayed.

  Step 3 Run:

test-type http

The test type is set to HTTP.

  Step 4 Run:

destination-address ipv4 ipv4-address

The destination address is configured.

  Step 5 (Optional) Run the following commands as required to configure parameters for the HTTP test.

 Run:

description string

A description is configured for the test instance.

 Run:

frequency interval

The test period is set for the NQA test instance.

 Run:

timeout time

The timeout period of a probe is set for the NQA test instance.

 Run:

dns-server ipv4 ip-address

The DNS server address is configured.

 Run:

destination-port port-number

The destination port number is configured.

 Run:

source-address ipv4 ipv4-address

  The source IP address is configured.

 Run:

source-port port-number

The source port number is configured.

 Run:

ttl number

The TTL value in the NQA test packet is set.

 Run:

sendpacket passroute

The NQA test instance is configured to send packets without searching the routing table.

 Run:

probe-count number

The number of probes in a test is set.

 Run:

tos value

Type of Service (TOS) is set for the test packet.

 Run:

fail-percent percent

The failure percentage is set for the NQA test instance.

 Run:

vpn-instance vpn-instance-name

The VPN instance name is configured.

 Run:

records history number

The maximum number of historical records is set for the NQA test instance.

 Run:

records result number

The maximum number of result records is set for the NQA test instance.

 Run:

agetime hh:mm:ss

The aging time is set for the NQA test instance.

  Step 6 Run:

http-operation get

The HTTP operation type is set to Get.

  Step 7 Run:

http-url deststring [ verstring ]

The URL of the web page that the HTTP test accesses and the HTTP version are configured.

  If no HTTP version is configured, HTTP1.0 is supported by default. You can set the version to HTTP1.1.
