ONFIGURATION
CAUTION:
When the system is testing, parameters that are configured in the NQA test
■
group view cannot be changed except the simple description of the operations
and the condition of sending the Trap information to the network
management system.
You can use the undo test-enable command to stop the test at any time. And
■
you can stop the test by means of disabling the NQA client or deleting the test
group.
If you assume the connection mode as direct mode but set a TTL value at the
■
same time, this TTL value does not take effect.
It is not allowed to configure the source IP and the destination IP both to 0 or F.
■
Other values are all allowed to configure.Source address can only be the Layer
3 interface configured with IP address.
When you test for the first time, the first probe packet loses if there is no
■
information of the destination address in the switch and the configured packet
size is over the maximum size of a single packet.
All of the parameters and test results can be displayed or set by MIB with the
■
network management tool.
Network requirements
Configure the simple NQA test. The type is ICMP.
■
The destination address is 192.168.80.80. It is the address of a PC and
■
accessible to the switch which performs the NQA test.
