System maintenance and debugging
Use the ping, tracert, and system debugging utilities to test network connectivity and identify network
problems.
Ping
The ping utility sends ICMP echo requests (ECHO-REQUEST) to the destination device. Upon receiving
the requests, the destination device responds with ICMP echo replies (ECHO-REPLY) to the source device.
The source device outputs statistics about the ping operation, including the number of packets sent,
number of echo replies received, and the round-trip time. You can measure the network performance by
analyzing these statistics.
Using a ping command to test network connectivity
To execute ping commands to test network connectivity:
Task Command Remarks
Test the network connectivity
to an IP address.
• For IPv4 networks:
ping [ ip ] [ -a source-ip | -c count | -f |
-h ttl | -i interface-type interface-number
| -m interval | -n | -p pad | -q | -r | -s
packet-size | -t timeout | -tos tos | -v ] *
host
• For IPv6 networks:
ping ipv6 [ -a source-ipv6 | -c count |
-m interval | -s packet-size | -t timeout ]
* host [ -i interface-type
interface-number ]
Use either approach.
Available in any view.
NOTE:
•
For a low-speed network, H3C recommends that you set a larger value for the timeout timer (indicated
by the -t parameter in the command) when configuring the ping command.
• Only the directly connected segment address can be pinged if the outgoing interface is specified with
the -i keyword.

Network requirements
Test the network connectivity between Device A and Device C in Figure 1 . If they can reach each other,
get detailed information about routes from Device A to Device C.
