Configuring the DLSw operation
The DLSw operation measures the response time of a DLSw device.
To configure the DLSw 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 DLSw type and
enter its view.
type dlsw
N/A
4.
Specify the destination IP
address of probe packets.
destination ip
ip-address
By default, no destination IP
address is specified.
5.
(Optional.) Specify the
source IP address of probe
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 probe packets can be sent out.
Configuring the path jitter operation
The path jitter operation measures the jitter, negative jitters, and positive jitters from the NQA client to
each hop on the path to the destination.
Before you configure the path jitter 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.
•
Enable sending ICMP destination unreachable messages on the destination device. If the
destination device is an HPE device, use the
ip unreachables enable
command.
For more information about the
ip ttl-expires enable
and
ip unreachables enable
commands, see
Layer 3—IP Services Command Reference
