43.1.3.6 Detecting and Maintaining IP Addressing
Perform the following operations to detect and maintain the network:
1. Clearing cache, list and database
You can clear all content in a cache, list or the database. When you think some content is ineffective, you can
clear it.
Run the following command in management mode to clear the cache, list and database:
Run… To
clear arp-cache
Clear the IP ARP cache.
2. Displaying statistics data about system and network
The system can display designated statistics data, such as IP routing table, cache and database. All such
information helps you know the usage of the systematic resources and solve network problems. The system
also can display the reachability of the port and the routes that the message takes when the message runs in
the network.
All relative operations are listed in the following table. For how to use these commands, refer to Chapter “IP
Addressing Commands”.
Run the following commands in management mode:
Run… To
show arp
Display content in the ARP table.
show hosts
Display the cache table about hostname-to-IP
mapping.
show ip interface [type number]
Display the interface state.
show ip route [protocol]
Display the current state of the routing table.
ping {host | address}
Test the reachability of the network node.
