Configuration Guide
I. Enabling HWPing Server
Some testing operations of the HWPing function require the cooperation between
Server and Client, such as jitter test (analysis on the delay variations in UDP datagram
transmission) and UDP/TCP test on a specified port. HWPing Server is responsible for
handling the test packets sent from HWPing Client, but it can work only if it has been
enabled on the router.
You may enable both HWPing Client and Server on the same router. In other words, a
router can provide both services of HWPing Server and Client.
Perform the following configurations in system view.
Table 4-1 Enable Server
Enable HWPing Server.
Disable HWPing Server.
By default, HWPing Server is disabled.
II. Configuring the services to which HWPing Server listens
With respect to TCP or UDP HWPing test, HWPing Server responds to the test initiated
by a client via the listening function. HWPing Server only responds to some particular
clients, that is, the clients whose addresses and port numbers have been configured on
the server.
You may create multiple TCP and UDP listening services on HWPing Server, each for a
combination of destination address and port.
Perform the following configurations in system view.
Table 4-2 Configure UDP listening port
Configure a UDP listening service.
Disable the UDP listening service.
Configure a TCP listening service.
Disable the TCP listening service.
By default, no UDP or TCP listening service is configured.
