DHCP operation configuration example

As shown in Figure 45, configure a DHCP operation to test the time required for Switch A to obtain an IP address from the DHCP server.

# Create a DHCP operation to be performed on interface VLAN-interface 2.

<SwitchA> system-view
[SwitchA] nqa entry admin test1
[SwitchA-nqa-admin-test1] type dhcp
[SwitchA-nqa-admin-test1-dhcp] operation interface vlan-interface 2

# Enable the saving of history records.

[SwitchA-nqa-admin-test1-dhcp] history-record enable
[SwitchA-nqa-admin-test1-dhcp] quit

# Start the DHCP operation.

[SwitchA] nqa schedule admin test1 start-time now lifetime forever

# Stop the DHCP operation after a period of time.

[SwitchA] undo nqa schedule admin test1

# Display the results of the DHCP operation.

[SwitchA] display nqa result admin test1
  NQA entry (admin admin, tag test1) test results:
      Send operation times: 1              Receive response times: 1
      Min/Max/Average round trip time: 624/624/624
      Square-Sum of round trip time: 389376
      Last succeeded probe time: 2011-11-22 09:56:03.2
    Extended results:
      Packet loss in test: 0%
      Failures due to timeout: 0
      Failures due to disconnect: 0
      Failures due to no connection: 0
      Failures due to sequence error: 0
      Failures due to internal error: 0
      Failures due to other errors: 0
      Packet(s) arrived late: 0

# Display the history records of the DHCP operation.

[SwitchA] display nqa history admin test1
  NQA entry (admin admin, tag test1) history record(s):
    Index      Response     Status           Time
    1          624          Succeeded        2011-11-22 09:56:03.2

The output shows that Switch A uses 624 milliseconds to obtain an IP address from the DHCP server.
