sys-cmd ping6

sys-cmd ping6 sends an ICMPv6 echo request to an IPv6 target from the route table selected in WEB-CLI; it shows the round-trip time of every response and, at the end, the packet loss summary. It is the IPv6 equivalent of the ping command.

Command Summary

TR7 WEB-CLI · sys-cmd ping6

# type ping6 and press Tab: a free parameter

admin@TR7LBWAF01> sys-cmd ping6

<ping6-parameter-1>

 

admin@TR7LBWAF01> sys-cmd ping6 <parameters> <ipv6-target>

Everything written after the word ping6 is passed to the tool as it is. There is no mandatory field; the target address is written together with the parameters according to the tool's own syntax.

How It Works

Subject	Behavior
Context	The packets are sent from within the selected v-device and route table; the IPv6 addresses and the routes of that route table are used.
Duration	If -c is not given, it sends packets without stopping.
Stopping	Ctrl+C stops the tool. If the tool does not close within 10 seconds, it is terminated by force.
Pipe	The output can be filtered with | or written to a file with to-file.
Recording	Every run is written to the user logs.

Frequently Used Parameters

Parameter	What it does	What is written after it
-c	Limits the number of packets to be sent	A number (e.g. 4)
-i	Changes the waiting time between two packets	Seconds (e.g. 0.5)
-s	Changes the size of the data section of the packet	Bytes
-I	Selects the interface from which the packet will go out; it is required for the link-local addresses that begin with fe80::	An interface name
-q	Shows only the summary at the end	—

The table summarizes frequently used parameters; the full list and behavior depend on the version of the tool on the device.

Examples

TR7 WEB-CLI · A) Four packets to a global IPv6 address

admin@TR7LBWAF01> sys-cmd ping6 -c 4 2001:db8::15

admin@TR7LBWAF01>  

TR7 WEB-CLI · B) A link-local neighbor by specifying the interface

admin@TR7LBWAF01> sys-cmd ping6 -c 3 -I <interface> fe80::1

admin@TR7LBWAF01>  

TR7 WEB-CLI · C) At half-second intervals, summary only

admin@TR7LBWAF01> sys-cmd ping6 -c 10 -i 0.5 -q 2001:db8::15

admin@TR7LBWAF01>  

Things to Know

• IPv4 works, IPv6 does not. An IPv6 address or an IPv6 route may be missing in the selected route table; the route table settings are checked from the Route Tables page.
• A link-local address. Because the addresses that begin with fe80:: can repeat on every interface, a request sent without specifying the interface mostly gives an error.
• The interface names are seen in the output of ip show address.
