source-address (Trace test instance)

Function

The source-address command configures the source IP address of a NQA trace test instance.

The undo source-address command restores the default source IP address.

By default, the IP/MAC address of the interface that sends test packets is used as the source IP address.

Format

source-address ipv4 srcAddress

source-address ipv6 srcAddr6

undo source-address

Parameters

Parameter	Description	Value
ipv6 srcAddr6	Specifies the source IPv6 address of an NQA test instance.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
ipv4 srcAddress	Specifies the source IPv4 address of an NQA test instance.	The IP address is in dotted decimal notation.

Usage Guidelines

Usage Scenario

To configure the source IP address of a test instance, run the source-address command. When test packets arrive at the destination address, the receive end returns reply packets to the configured source IP address.

Configuration Impact

If the specified source IP address is not the IP address of the device that sends test packets, no reply packet will be received.

Precautions

If parameters need to be changed during the running of the test instance, the system prompts you whether to terminate the test instance. Press "Y" or "N" as required.

If you press "Y", the test instance is terminated and parameters changed. The settings take effect after being committed. To restart the test instance, run the start command.
If you press "N", the test instance keeps running, and the parameters fail to be modified.
The same test instance can be assigned only one source address, and the latest configuration overrides the previous one.

Example

# Set the source IPv6 address to 2001:db8:1::1 for the test instance named user test.

<HUAWEI> system-view
[~HUAWEI] nqa test-instance user test
[*HUAWEI-nqa-user-test] test-type trace
[*HUAWEI-nqa-user-test] source-address ipv6 2001:db8:1::1

# Set the source IP address to 10.1.1.1, respectively, for the test instance named user test.

<HUAWEI> system-view
[~HUAWEI] nqa test-instance user test
[*HUAWEI-nqa-user-test] test-type trace
[*HUAWEI-nqa-user-test] source-address ipv4 10.1.1.1
