I'm doing ping between 2 RH servers through a VPN site2site tunnel and in some times I got in the result pipe 2 and another pipe 3 as I mark it in blue color below.

e.g.

64 bytes from 192.168.1.10: icmp_seq=0 ttl=128 time=0.229 ms
64 bytes from 192.168.1.10: icmp_seq=1 ttl=128 time=0.287 ms
64 bytes from 192.168.1.10: icmp_seq=2 ttl=128 time=0.278 ms

--- 192.168.1.10 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2000ms
rtt min/avg/max/mdev = 0.229/0.264/0.287/0.031 ms, pipe 2

My questions:

What's the difference between pipe 2 and pipe 3 and what's the meaning of it?

Ok, if any body can give the location where I can find the full description and syntax of PING command in RH, may be I can find there the meaning of pipe in the ping result.
