Configuring ICMP echo tests
ICMP echo tests of an NQA test group uses ICMP echo response information to test reachability of a destination host. An ICMP echo test has the same function as the ping command but provides more output information. In addition, you can specify the next hop for ICMP echo tests. ICMP echo tests are used to locate connectivity problems in a network.
NQA ICMP echo tests are not supported in IPv6 networks. To test the reachability of an IPv6 address, use the ping ipv6 command. For more information about the command, see Network Management and Monitoring Command Reference.
To configure ICMP echo tests:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter NQA test group view. | nqa entry admin-name operation-tag | N/A |
3. Configure the test type as ICMP echo, and enter test type view. | type icmp-echo | N/A |
4. Configure the destination address of ICMP echo requests. | destination ip ip-address | By default, no destination IP address is configured. |
5. Configure the size of the data field in each ICMP echo request. | data-size size | Optional. 100 bytes by default. |
6. Configure the string to be filled in the data field of each ICMP echo request. | data-fill string | Optional. By default, the string is the hexadecimal number 00010203040506070809. |
7. Apply ICMP echo tests to the specified VPN. | vpn-instance vpn-instance-name | Optional. By default, ICMP echo tests apply to the public network. |
8. Configure the source interface for ICMP echo requests. | source interface interface-type interface-number | Optional. By default, no source interface is configured for probe packets. The requests take the IP address of the source interface as their source IP address when no source IP address is specified. The specified source interface must be up. Otherwise, no ICMP echo requests can be sent out. |
9. Configure the source IP address of ICMP echo requests. | source ip ip-address | Optional. By default, no source IP address is configured. If you configure both the source ip command and the source interface command, the source ip command takes effect. The source IP address must be the IP address of a local interface. The local interface must be up. Otherwise, no ICMP echo requests can be sent out. |
10. Configure the next hop IP address of ICMP echo requests. | next-hop ip-address | Optional. By default, no next hop IP address is configured. |
11. Configure optional parameters. | Optional. |
