Configuring The Icmp Echo Operation - HP 6125XLG Configuration Manual

Configuring the ICMP echo operation

The ICMP echo operation measures the reachability of a destination device. It has the same function as
the ping command, but provides more output information. In addition, if multiple paths exist between the
source and destination devices, you can specify the next hop for the ICMP echo operation.
The ICMP echo operation is not supported in IPv6 networks. To test the reachability of an IPv6 address,
use the ping ipv6 command. For more information about the command, see Network Management and
Monitoring Command Reference.
To configure the ICMP echo operation:
Step
1. Enter system view.
2. Create an NQA operation
and enter NQA operation
view.
3. Specify the ICMP echo type
and enter its view.
4. Specify the destination
address of ICMP echo
requests.
5. (Optional.) Specify the
payload size in each ICMP
echo request.
6. (Optional.) Specify the string
to be filled in the payload of
each ICMP echo request.
7. (Optional.) Specify the VPN
where the operation is
performed.
8. (Optional.) Specify the source
interface and the source IP
address of ICMP echo
requests.
9. (Optional.) Specify the next
hop for ICMP echo requests.

Remarks
N/A
By default, no NQA operation is
created.
N/A
By default, no destination IP
address is specified.
The default setting is 100 bytes.
The default setting is the
hexadecimal number
00010203040506070809.
By default, the operation is
performed on the public network.
By default, no source interface or
source IP address is specified. The
requests take the primary IP
address of the outgoing interface
as their source IP address.
If you configure both source ip and
source interface, the source ip
command takes effect.
The specified source interface must
be up. The source IP address must
be the IP address of a local
interface and the interface must be
up.
By default, no next hop is
configured.
