Specifications Calculation Supported by eSight

  • Latency: interval for receiving a packet minus the interval for sending the packet.
  • Jitter: interval for receiving two consecutive packets minus the interval for sending them.
  • Packet loss rate = (Total number of sent packets - Total number of received packets)/Total number of packets x 100%
NOTE:

TCP and FTP test instances are used as examples. Packet loss rate = (Total number of probes - Number of successful probes)/Total number of probes x 100%

Device Configuration

To perform test instances on eSight, you must perform the settings in Table 12-74.

Table 12-74 Device Configuration

Test Instance

Device Configuration Requirements

ICMP Echo

The source and destination devices can ping successfully.

ICMP Jitter

The source and destination devices can ping successfully.

If Enable the LPU to send packets is set to Yes, the ICMP service must be enabled on the destination device.

Run the following commands to enable the ICMP service:

<Huawei> system-view

[Huawei] nqa-server icmp-server 10.137.61.39

In the command, 10.137.61.39 is the destination device IP address.

UDP Echo

The UDP service must be enabled on the destination device.

Run the following commands to enable the UDP service:

<Huawei> system-view

[Huawei] nqa-server udpecho 10.137.61.39 33434

In the command, 10.137.61.39 is the destination device IP address and 33434 is the UDP port number.

UDP Jitter

The UDP service must be enabled on the destination device.

Run the following commands to enable the UDP service:

<Huawei> system-view

[Huawei] nqa-server udpecho 10.137.61.39 33434

In the command, 10.137.61.39 is the destination device IP address and 33434 is the UDP port number.

TCP Connect

The TCP service must be enabled on the destination device.

Run the following commands to enable the TCP service:

<Huawei> system-view

[Huawei] nqa-server tcpconnect 10.137.61.39 33433

In the command, 10.137.61.39 is the destination device IP address and 33433 is the TCP port number.

SNMP

None

DNS

The DNS service must be enabled on the source device.

Run the following commands to enable the DNS service:

<Huawei> system-view

[Huawei] dns resolve

[Huawei] dns server 10.137.61.75

[Huawei] dns domain net

[Huawei] dns domain com

In the command, 10.137.61.75 is the DNS server IP address.

DHCP

The DHCP server function must be enabled on the VLANIF interface of the destination device.

Run the following command to enable the DHCP server function:

<Huawei> system-view

[Huawei] interface Vlanif20

[Huawei-Vlanif20] ip address 10.137.61.75 255.255.255.0

[Huawei-Vlanif20] dhcp select interface

In the commands, Vlanif20 is the VLANIF interface, 10.137.61.75 is the DHCP server IP address, and 255.255.255.0 is the subnet mask of the IP address.

HTTP

None

FTP

The FTP service must be enabled on the destination device.

Run the following commands to enable the FTP service:

<Huawei> system-view
