So far, you’ve seen many examples of pinging devices to test IP connectivity and name resolution
using the DNS server. To see all the different protocols that you can use with the ping
program, type ping ?, like so:
Corp#ping ?
WORD Ping destination address or hostname
clns CLNS echo
ip IP echo
srb srb echo
tag Tag encapsulated IP echo
The ping output displays the minimum, average, and maximum times it takes for a ping
packet to find a specified system and return. Here’s an example:
Corp#ping R1
Translating "R1"...domain server (192.168.0.70)[OK]
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.2.2.2, timeout
is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max
= 1/2/4 ms
