Usage guidelines
Suppose a device is connected to another device through PPP, for example, a device is connected to the
operator's access server through a dial-up link. In this case, you can configure a device to request its peer
for the DNS server IP address during IPCP negotiation, so that the device can resolve domain names
through the DNS server specified by the peer.
You can check the DNS server IP addresses of a port by displaying information about the port.
