IP Service Configuration 43.4
It is to describe how to configure optional IP service. For the details of the IP service commands, refer to
section “IP Service Commands”.
43.4.1 Configuring IP Service
Optional IP service configuration tasks are listed as follows:
Managing IP connection
Configuring performance parameters
Configuring default gateway
Detecting and maintaining IP network
The above operations are not mandatory. You can perform the operations according to your requirements.
43.4.1.1 Managing IP Connection
The IP protocol provides a series of services to control and manage IP connections. Most of these services
are provided by ICMP. The ICMP message is sent to the host or other routing switches when the routing
switch or the access server detects faults in the IP message header. ICMP is mainly defined in RFC 792.
Perform the following different operations according to different IP connection conditions:
1. Sending ICMP unreachable message
If the system receives a message and cannot send it to the destination, such as no routes, the system will
send an ICMP-unreachable message to the source host. The function of the system is enabled by default.
If the function is disabled, you can run the following command in interface configuration mode to enable the
function.
