DHCP operation configuration example
Network requirements
As shown in Figure 9, configure a DHCP operation to test the time required for Switch A to obtain an IP address from the DHCP server (Switch B).
Figure 9: Network diagram
Configuration procedure
# Create a DHCP operation.
<SwitchA> system-view [SwitchA] nqa entry admin test1 [SwitchA-nqa-admin-test1] type dhcp
# Specify the DHCP server address 10.1.1.2 as the destination address.
[SwitchA-nqa-admin-test1-dhcp] destination ip 10.1.1.2
# 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
# After the DHCP operation runs for a period of time, stop the operation.
[SwitchA] undo nqa schedule admin test1
# Display the most recent result 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: 512/512/512 Square-Sum of round trip time: 262144 Last succeeded probe time: 2011-11-22 09:56:03.2 Extended results: Packet loss ratio: 0% Failures due to timeout: 0 Failures due to internal error: 0 Failures due to other errors: 0
# Display the history records of the DHCP operation.
[SwitchA] display nqa history admin test1 NQA entry (admin admin, tag test1) history records: Index Response Status Time 1 512 Succeeded 2011-11-22 09:56:03.2
The output shows that it took Switch A 512 milliseconds to obtain an IP address from the DHCP server.
