NQA operation
The following describes how NQA performs different types of operations:
A TCP or DLSw operation sets up a connection.
An ICMP jitter, UDP jitter, or voice operation sends a number of probe packets. The number of probe packets is set by using 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:
The operation uses tracert to obtain the path from the NQA client to the destination. A maximum of 64 hops can be detected.
The NQA client sends ICMP echo requests to each hop along the path. The number of ICMP echo requests is set by using the probe packet-number command.
A UDP tracert operation determines the routing path from the source to the destination. The number of the probe packets sent to each hop is set by using the probe count command.
