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.
