Using ping, tracert, and system 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
Task Command Remarks
Test the network connectivity to an
IP address.
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
Available in any view.
When you configure the
ping command for a
low-speed network, set
a larger value for the -t
timeout option, the
timeout timer.

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.
