Configuring NQA

Overview

Network quality analyzer (NQA) allows you to measure network performance, verify the service levels for IP services and applications, and troubleshoot network problems. It provides the following types of operations:

·          ICMP echo.

·          ICMP jitter.

·          DHCP.

·          DLSw.

·          DNS.

·          FTP.

·          HTTP.

·          Path jitter.

·          SNMP.

·          TCP.

·          UDP echo.

·          UDP jitter.

·          UDP tracert.

·          Voice.

As shown in Figure 1, the NQA source device (NQA client) sends data to the NQA destination device by simulating IP services and applications to measure network performance. The obtained performance metrics include the one-way latency, jitter, packet loss, voice quality, application performance, and server response time.

All types of NQA operations require the NQA client, but only the TCP, UDP echo, UDP jitter, and voice operations require the NQA server. The NQA operations for services that are already provided by the destination device such as FTP do not need the NQA server.

You can configure the NQA server to listen and respond to specific IP addresses and ports to meet various test needs.

Figure 1 Network diagram

 

NQA operation

The following describes how NQA performs different types of operations:

·          A TCP or DLSw operation sets up a connection.

·          An ICMP jitter, UDP jitter, or voice operation sends a number of probe packets. The number of probe packets is set by using the probe packet-number command.

·          An FTP operation uploads or downloads a file.

·          An HTTP operation gets a Web page.

·          A DHCP operation gets an IP address through DHCP.

·          A DNS operation translates a domain name to an IP address.

·          An ICMP echo operation sends an ICMP echo request.

·          A UDP echo operation sends a UDP packet.

·          An SNMP operation sends one SNMPv1 packet, one SNMPv2c packet, and one SNMPv3 packet.

·          A path jitter operation is accomplished in the following steps:

a.    The operation uses tracert to obtain the path from the NQA client to the destination. A maximum of 64 hops can be detected.

b.    The NQA client sends ICMP echo requests to each hop along the path. The number of ICMP echo requests is set by using the probe packet-number command.

·          A UDP tracert operation determines the routing path from the source to the destination. The number of the probe packets sent to each hop is set by using the probe count command.

Collaboration

NQA can collaborate with the Track module to notify application modules of state or performance changes so that the application modules can take predefined actions.

Figure 2 Collaboration

 

The following describes how a static route destined for 192.168.0.88 is monitored through collaboration:

1.        NQA monitors the reachability to 192.168.0.88.

2.        When 192.168.0.88 becomes unreachable, NQA notifies the Track module of the change.

3.        The Track module notifies the static routing module of the state change.

4.        The static routing module sets the static route to invalid according to a predefined action.

For more information about collaboration, see High Availability Configuration Guide.

Threshold monitoring

Threshold monitoring enables the NQA client to take a predefined action when the NQA operation performance metrics violate the specified thresholds.

Table 1 describes the relationships between performance metrics and NQA operation types.

3.       Specify the ICMP echo type and enter its view.

type icmp-echo

N/A

4.       Specify the destination IP address for ICMP echo requests.

destination ip ip-address

By default, no destination IP address is specified.

5.       (Optional.) Set the payload size for each ICMP echo request.

data-size size

The default setting is 100 bytes.

6.       (Optional.) Specify the payload fill string for ICMP echo requests.

data-fill string

The default payload fill string is the hexadecimal string 00010203040506070809.

7.       (Optional.) Specify the output interface for ICMP echo requests.

out interface interface-type interface-number

By default, the output interface for ICMP echo requests is not specified. The NQA client determines the output interface based on the routing table lookup.

8.       (Optional.) Specify the source IP address for ICMP echo requests.

·         Use the IP address of the specified interface as the source IP address:
source interface interface-type interface-number

·         Specify the source IP address:
source ip ip-address

By default, the requests take the primary IP address of the output interface as their source IP address.

If you execute the source interface and source ip commands multiple times, the most recent configuration takes effect.

The specified source interface must be up.

The specified 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.

9.       (Optional.) Specify the next hop IP address for ICMP echo requests.

next-hop ip ip-address

By default, no next hop IP address is configured.

 

Configuring the ICMP jitter operation

The ICMP jitter operation measures unidirectional and bidirectional jitters. The operation result helps you to determine whether the network can carry jitter-sensitive services such as real-time voice and video services.

The ICMP jitter operation works as follows:

1.        The NQA client sends ICMP packets to the destination device.

2.        The destination device time stamps each packet it receives, and then sends the packet back to the NQA client.

3.        Upon receiving the responses, the NQA client calculates the jitter according to the timestamps.

To configure the ICMP jitter operation:

 

Step

Command

Remarks

1.       Enter system view.

The default setting is 20 milliseconds.

7.       (Optional.) Specify how long the NQA client waits for a response from the server before it regards the response times out.

probe packet-timeout timeout

The default setting is 3000 milliseconds.

8.       (Optional.) Specify the source IP address for ICMP 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 ICMP packets can be sent out.

 

 

NOTE:

Use the display nqa result or display nqa statistics command to verify the ICMP jitter operation. The display nqa history command does not display the ICMP jitter operation results or statistics.

 

Configuring the DHCP operation

The DHCP operation measures whether or not the DHCP server can respond to client requests. DHCP also measures the amount of time it takes the NQA client to obtain an IP address from a DHCP server.

The NQA client simulates the DHCP relay agent to forward DHCP requests for IP address acquisition from the DHCP server. The interface that performs the DHCP operation does not change its IP address. When the DHCP operation completes, the NQA client sends a packet to release the obtained IP address.

To configure the DHCP operation:

 

Step

Command

Remarks

1.       Enter system view.

system-view

N/A

2.       Create an NQA operation and enter NQA operation view.

Configuring the FTP operation

The FTP operation measures the time for the NQA client to transfer a file to or download a file from an FTP server.

When you configure the FTP operation, follow these restrictions and guidelines:

·          When you perform the put operation with the filename command configured, make sure the file exists on the NQA client.

·          If you get a file from the FTP server, make sure the file specified in the URL exists on the FTP server.

·          The NQA client does not save the file obtained from the FTP server.

·          Use a small file for the FTP operation. A big file might result in transfer failure because of timeout, or might affect other services for occupying much network bandwidth.

Configuring the UDP jitter operation

CAUTION

CAUTION:

To ensure successful UDP jitter operations and avoid affecting existing services, do not perform the operations on well-known ports from 1 to 1023.

 

Jitter means inter-packet delay variance. A UDP jitter operation measures unidirectional and bidirectional jitters. The operation result helps you to determine whether the network can carry jitter-sensitive services such as real-time voice and video services through the UDP jitter operation.

The UDP jitter operation works as follows:

1.        The NQA client sends UDP packets to the destination port.

2.        The destination device time stamps each packet it receives, and then sends the packet back to the NQA client.

3.        Upon receiving the responses, the NQA client calculates the jitter according to the timestamps.

The UDP jitter operation requires both the NQA server and the NQA client. Before you perform the UDP jitter operation, configure the UDP listening service on the NQA server. For more information about UDP listening service configuration, see "Configuring the NQA server."

Configuring the voice operation

CAUTION

CAUTION:

To ensure successful voice operations and avoid affecting existing services, do not perform the operations on well-known ports from 1 to 1023.

 

The voice operation measures VoIP network performance.

The voice operation works as follows:

1.        The NQA client sends voice packets at sending intervals to the destination device (NQA server).

The voice packets are of one of the following codec types:

¡  G.711 A-law.

¡  G.711 µ-law.

¡  G.729 A-law.

2.        The destination device time stamps each voice packet it receives and sends it back to the source.

3.        Upon receiving the packet, the source device calculates the jitter and one-way delay based on the timestamp.

The following parameters that reflect VoIP network performance can be calculated by using the metrics gathered by the voice operation:

·          Calculated Planning Impairment Factor (ICPIF)—Measures impairment to voice quality in a VoIP network. It is decided by packet loss and delay. A higher value represents a lower service quality.

·          Mean Opinion Scores (MOS)—A MOS value can be evaluated by using the ICPIF value, in the range of 1 to 5. A higher value represents a higher service quality.

The evaluation of voice quality depends on users' tolerance for voice quality. For users with higher tolerance for voice quality, use the advantage-factor command to set an advantage factor. When the system calculates the ICPIF value, it subtracts the advantage factor to modify ICPIF and MOS values for voice quality evaluation.

The voice operation requires both the NQA server and the NQA client. Before you perform a voice operation, configure a UDP listening service on the NQA server. For more information about UDP listening service configuration, see "Configuring the NQA server."

The voice operation cannot repeat.

Configuring threshold monitoring

This feature allows you to monitor the NQA operation running status.

Threshold types

An NQA operation supports the following threshold types:

·          average—If the average value for the monitored performance metric either exceeds the upper threshold or goes below the lower threshold, a threshold violation occurs.

·          accumulate—If the total number of times that the monitored performance metric is out of the specified value range reaches or exceeds the specified threshold, a threshold violation occurs.

·          consecutive—If the number of consecutive times that the monitored performance metric is out of the specified value range reaches or exceeds the specified threshold, a threshold violation occurs.

Threshold violations for the average or accumulate threshold type are determined on a per NQA operation basis. The threshold violations for the consecutive type are determined from the time the NQA operation starts.

Triggered actions

The following actions might be triggered:

·          none—NQA displays results only on the terminal screen. It does not send traps to the NMS.

·          trap-only—NQA displays results on the terminal screen, and meanwhile it sends traps to the NMS.

·          trigger-only—NQA displays results on the terminal screen, and meanwhile triggers other modules for collaboration.

The DNS operation does not support the action of sending trap messages.

Reaction entry

In a reaction entry, configure a monitored element, a threshold type, and an action to be triggered to implement threshold monitoring.

The state of a reaction entry can be invalid, over-threshold, or below-threshold.

·          Before an NQA operation starts, the reaction entry is in invalid state.

·          If the threshold is violated, the state of the entry is set to over-threshold. Otherwise, the state of the entry is set to below-threshold.

If the action is trap-only for a reaction entry, a trap message is sent to the NMS when the state of the entry changes.

Configuration procedure

Before you configure threshold monitoring, configure the destination address of the trap messages by using the snmp-agent target-host command. For more information about the command, see Network Management and Monitoring Command Reference.

Scheduling the NQA operation on the NQA client

The NQA operation works between the specified start time and the end time (the start time plus operation duration). If the specified start time is ahead of the system time, the operation starts immediately. If both the specified start and end time are ahead of the system time, the operation does not start. To display the current system time, use the display clock command.

When you schedule an NQA operation, follow these restrictions and guidelines:

·          You cannot enter the operation type view or the operation view of a scheduled NQA operation.

·          A system time adjustment does not affect started or completed NQA operations. It affects only the NQA operations that have not started.

To schedule the NQA operation on the NQA client:
