R21xx-HP FlexFabric 11900 Network Management and Monitoring Command Reference

Field Descri

tion

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 during the timeout period, no

information is displayed.

• bytes—Number of data bytes in the ICMP reply.

• icmp_seq—Packet sequence, used to determine whether a segment is

lost, disordered or repeated.

• ttl—TTL value in the ICMP 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.

--- 1.1.2.2 ping statistics --- 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 packets not responded 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.

Parameters

-a source-ipv6: Specifies the source IPv6 address of an ICMP echo request. It must be a valid IPv6

address configured on the device. If this option is not specified, the source IPv6 address of an ICMP echo

request is the IPv6 address of the outbound interface of the request. (The address selection rule is defined

by RFC 3484.)

-c count: Specifies the number of times that an ICMPv6 echo request is sent. The count argument is in the

range of 1 to 4294967295. The default value is 5.

-m interval: Specifies the interval (in milliseconds) to send an ICMPv6 echo reply. The interval argument

is in the range of 1 to 65535. The default value is 1000.

-q: Displays only statistics. If this keyword is not specified, all information including the statistics is

displayed.

-s packet-size: Specifies length (in bytes) of an ICMPv6 echo request (not including the IPv6 packet

header and the ICMPv6 packet header). The packet-size argument is in the range of 20 to 8100. The

default value is 56.
