Ping uses the Internet Control Message Protocol (ICMP) Echo messages to determine if a remote host is active or inactive and to determine the round-trip delay when communicating with it. Ping tool sends ICMP (type 8) message to the host and waits for the ICMP echo-reply (type 0). The interval between these events is called a round trip. If the response (that is called pong) has not come until the end of the interval, we assume it has timed out. The second significant parameter reported is TTL (Time to Live). Is decremented at each machine in which the packet is processed. The packet will reach its destination only when the TTL is greater than the number of routers between the source and the destination.
RouterOS Ping tool allows you to configure various additional parameters like:
Let's take a look ar very simple example:
[admin@MikroTik] > /tool/ping address=10.155.126.252 count=5 interval=200ms
SEQ HOST SIZE TTL TIME STATUS
0 10.155.126.252 56 64 0ms
1 10.155.126.252 56 64 0ms
2 10.155.126.252 56 64 0ms
3 10.155.126.252 56 64 0ms
4 10.155.126.252 56 64 0ms
sent=5 received=5 packet-loss=0% min-rtt=0ms avg-rtt=0ms max-rtt=0ms |
The same we can achieve with more shorter CLI command:
[admin@MikroTik] > /ping 10.155.126.252 count=5 interval=50ms
SEQ HOST SIZE TTL TIME STATUS
0 10.155.126.252 56 64 0ms
1 10.155.126.252 56 64 0ms
2 10.155.126.252 56 64 0ms
3 10.155.126.252 56 64 0ms
4 10.155.126.252 56 64 0ms
sent=5 received=5 packet-loss=0% min-rtt=0ms avg-rtt=0ms max-rtt=0ms |
It is also possible to ping multicast address to discover all hosts belonging to multicast group:
[admin@MikroTik] > /ping ff02::1
HOST SIZE TTL TIME STATUS
fe80::20c:42ff:fe49:fceb 56 64 1ms echo reply
fe80::20c:42ff:fe72:a1b0 56 64 1ms echo reply
fe80::20c:42ff:fe28:7945 56 64 1ms echo reply
fe80::21a:4dff:fe5d:8e56 56 64 3ms echo reply
sent=1 received=4 packet-loss=-300% min-rtt=1ms avg-rtt=1ms max-rtt=3ms |
Ping by DNS name:
[admin@MikroTik] > /ping www.google.com count=5 interval=50ms
SEQ HOST SIZE TTL TIME STATUS
0 216.58.207.228 56 51 14ms
1 216.58.207.228 56 51 13ms
2 216.58.207.228 56 51 13ms
3 216.58.207.228 56 51 13ms
4 216.58.207.228 56 51 13ms
sent=5 received=5 packet-loss=0% min-rtt=13ms avg-rtt=13ms max-rtt=14ms |
When you use the domain name and CLI for ping, router DNS will be used to resolve the address. When you use the Winbox Tools/Ping, your computer's DNS will be used to resolve the given address. |
This submenu allows enabling the mac ping server.
When mac ping is enabled, other hosts on the same broadcast domain can use the ping tool to ping mac address:
[admin@MikroTik] > /tool mac-server ping set enabled=yes |
Ping MAC address:
[admin@MikroTik] > /ping 00:0C:42:72:A1:B0
HOST SIZE TTL TIME STATUS
00:0C:42:72:A1:B0 56 0ms
00:0C:42:72:A1:B0 56 0ms
sent=2 received=2 packet-loss=0% min-rtt=0ms avg-rtt=0ms max-rtt=0ms |
