24Configuring the DLSw operationThe DLSw operation measures the response time of a DLSw device.To configure the DLSw operation:Step Command Remarks1. Enter system view. system-view N/A2. Create an NQA operationand enter NQA operationview.nqa entry admin-nameoperation-tagBy default, no NQA operation iscreated.3. Specify the DLSw type andenter its view. type dlsw N/A4. Specify the destination IPaddress of probe packets. destination ip ip-address By default, no destination IP addressis specified.5. (Optional.) Specify the sourceIP address of probe packets. source ip ip-addressBy default, no source IP address isspecified.The source IP address must be the IPaddress of a local interface, and theinterface must be up. Otherwise, noprobe packets can be sent out.Configuring the path jitter operationThe path jitter operation measures the jitter, negative jitters, and positive jitters from the NQA client toeach 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 sourceand destination devices. If the intermediate devices are H3C devices, use the ip ttl-expires enablecommand.• Enable sending ICMP destination unreachable messages on the destination device. If thedestination device is an H3C device, use the ip unreachables enable command.For more information about the ip ttl-expires enable and the ip unreachable enable command, see Layer3—IP Services Command Reference.To configure the path jitter operation:Step Command Remarks1.
