Table 1 Command output
Field Description
Ping 1.1.2.2 (1.1.2.2): 56 data
bytes, press CTRL_C to break
Test whether the device with IP address 1.1.2.2 is reachable. There
are 56 bytes in each ICMP echo request. Press
Ctrl+C
to abort the
ping operation.
56 bytes from 1.1.2.2: icmp_seq=0
ttl=254 time=4.685 ms
Received ICMP echo replies from the device whose IP address is
1.1.2.2. If no echo reply is received within the timeout period, no
information is displayed.
• bytes—Number of bytes in the ICMP echo reply.
• icmp_seq—Packet sequence, used to determine whether a
segment is lost, disordered or repeated.
• ttl—TTL value in the ICMP echo reply.
• time—Response time.
RR:
Routers through which the ICMP echo request passed. They are
displayed in inversed order, which means the router with a smaller
distance to the destination is displayed first.
--- Ping statistics for 1.1.2.2 --- Statistics on data received and sent in the ping operation.
5 packet(s) transmitted Number of ICMP echo requests sent.
5 packet(s) received Number of ICMP echo replies received.
0.0% packet loss Percentage of unacknowledged packets to the total packets sent.
round-trip min/avg/max/std-dev =
4.685/4.761/4.834/0.058 ms
Minimum/average/maximum/standard deviation response time, in
milliseconds.
