Configuring the CNA Agent
ExtremeWare XOS 11.3 Concepts Guide
637
The CNA Agent starts the specified test within 100 ms once it receives an authenticated and correctly
formatted test request from the CNA Server. The CNA Agent sends the test results to the CNA Server
within 100 ms of test completion.
Configuring the CNA Agent
To run the tests, configure the following:
●
Enable the CNA Agent.
●
Configure the IP address the CNA Agent uses to communicate with the CNA Server.
●
Configure the VLAN interface for the CNA Server
■
This step is optional. By default, the CNA Server uses the primary IP address on the switch’s
Default VLAN.
●
Clear the counters.
■
This step is optional.
●
Display the test results.
All these configurations are saved when you issue the
save configuration
command.
Enabling the CNA Agent
You enable the CNA Agent (test plug) by issuing the following command:
enable cna-testplug
Once you enable the CNA Agent, you register the CNA Agent with the CNA Server, and the CNA
Agent performs the requested network tests and reports the results.
To disable the CNA Agent, use the following command:
disable cna-testplug
Connecting to the CNA Server
After you enable the CNA Agent, you must configure this parameter to allow the CNA Agent to
register with the CNA Server. Use the following command:
configure cna-testplug scheduler ipaddress <ip_address>
You enter the IP address of the CNA Server. (With ExtremeWare XOS software version 11.2, this must be
an IPv4 address.)
Once you configure the IP address for the CNA server, the CNA Agent and the CNA Server exchange
SSL keys and establish encryption. After successful registration, you can connect with more than one
CNA Server, in which case you share the encryption key you negotiated with your initial CNA Server
connection.
At this time, the system establishes the socket connection to the CNA Server using this IP address. The
CNA Agent listens for instructions for the testing from this IP address.
