Configuring the UDP echo operation
The UDP echo operation measures the round-trip time between the client and a UDP port on the
NQA server.
The UDP echo operation requires both the NQA server and the NQA client. Before you perform a
UDP echo operation, configure a UDP listening service on the NQA server. For more information
about the UDP listening service configuration, see "
To configure the UDP echo operation:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create an NQA operation
and enter NQA operation
view.
nqa
entry
admin-name
operation-tag
By default, no NQA operations exist.
3.
Specify the UDP echo type
and enter its view.
type
udp-echo
N/A
4.
Specify the destination
address of UDP packets.
destination ip
ip-address
By default, no destination IP
address is specified.
The destination address must be the
same as the IP address of the
listening service configured on the
NQA server.
5.
Specify the destination port
of UDP packets.
destination port
port-number
By default, no destination port
number is specified.
The destination port number must
be the same as the port number of
the listening service on the NQA
server.
6.
(Optional.) Set the payload
size for each UDP packet.
data-size
size
The default setting is 100 bytes.
7.
(Optional.) Specify the
payload fill string for UDP
packets.
data-fill
string
The default payload fill string is the
hexhexadecimal string
00010203040506070809.
8.
(Optional.) Specify the
source port of UDP packets.
source port port-number
By default, no source port number is
specified.
9.
(Optional.) Specify the
source IP address of UDP
packets.
source ip ip-address
By default, the packets take the
primary IP address of the output
interface as their source IP address.
The source IP address must be the
IP address of a local interface, and
the interface must be up. Otherwise,
no UDP packets can be sent out.
Configuring the UDP tracert operation
The UDP tracert operation determines the routing path from the source device to the destination
device.
Before you configure the UDP tracert operation, perform the following tasks:
•
Enable sending ICMP time exceeded messages on the intermediate devices between the
source and destination devices. If the intermediate devices are HPE devices, use the
ip
ttl-expires enable
command.
