Usage guidelines
The following describes how NQA performs different types of NQA operations:
A TCP or DLSw operation sets up a connection.
A UDP jitter or voice operation sends a number of probe packets. The number of probe packets is
specified by the probe packet-number command.
An FTP operation uploads or downloads a file.
An HTTP operation gets a Web page.
A DHCP operation gets an IP address through DHCP.
A DNS operation translates a domain name to an IP address.
An ICMP echo operation sends an ICMP echo request.
A UDP echo operation sends a UDP packet.
An SNMP operation sends one SNMPv1 packet, one SNMPv2c packet, and one SNMPv3 packet.
A path jitter operation is accomplished in the following steps:
a.
The operation uses tracert to obtain the path from the NQA client to the destination. At
maximum of 64 hops can be detected.
b.
The NQA client sends ICMP echo requests to each hop along the path. The number of ICMP
echo requests is configurable with the probe packet-number command.
If an operation is to perform multiple probes, the system starts the next probe when it receives responses
to packets sent in the first probe, or when the probe timeout time expires.
This command is not available for the voice, UDP jitter, and path jitter operation. Each of these
operations performs only one probe.
Examples
# Configure the ICMP echo operation to perform 10 probes.
<Sysname> system-view
[Sysname] nqa entry admin test
[Sysname-nqa-admin-test] type icmp-echo
[Sysname-nqa-admin-test-icmp-echo] probe count 10
