DHCP operation configuration example
Network requirements
As shown in Figure 8 , configure and schedule a DHCP operation to test the time required for Router A to
obtain an IP address from the DHCP server (Router B).
Figure 8 Network diagram
Configuration procedure
# Create a DHCP operation to be performed to the destination IP address 10.1.1.2.
system-view
[RouterA] nqa entry admin test1
[RouterA-nqa-admin-test1] type dhcp
[RouterA-nqa-admin-test1-dhcp] destination ip 10.1.1.2
# Enable the saving of history records.
[RouterA-nqa-admin-test1-dhcp] history-record enable
[RouterA-nqa-admin-test1-dhcp] quit
# Start the DHCP operation.
[RouterA] nqa schedule admin test1 start-time now lifetime forever
# After the DHCP operation runs for a period of time, stop the operation.
[RouterA] undo nqa schedule admin test1
# Display the results of the DHCP operation.
[RouterA] display nqa result admin test
NQA entry (admin admin, tag test) 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: 2007-11-22 09:54:03.8
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.
[RouterA] display nqa history admin test
NQA entry (admin admin, tag test) history records:
Index Response Status Time
1 512 Succeeded 2007-11-22 09:54:03.8
The output shows that Router A uses 512 milliseconds to obtain an IP address from the DHCP server.
