Changing the Extreme Management Center Server IP Address
To change the IP address of the Extreme Management Center server, enter the
following command at the login prompt in the Console tab:
/opt/nac/configMgmtIP <IP address>
Enter the following command to start using the new Extreme Management
Center server:
nacctl restart
Changing Web Service Credentials
The Web Service credentials provide access to the NAC Appliance
Administration web page and the web services interface for the ExtremeControl
engine. Engines are shipped with a preconfigured default password.
If you have changed the credentials in NAC Manager (in the Appliance Settings
window) and then install a new engine that uses the default password, you will
not be able to monitor or enforce to the new engine until you change the
password on the engine using the command below. The credentials you enter
on the engine must match the credentials specified in NAC Manager in the
Appliance Settings window.
To change Web Service credentials, enter the following command at the login
prompt in the Console tab:
/opt/nac/configWebCredentials <username> <password>
Enter the following command to restart the engine:
nacctl restart
Changing the Engine IP Address and Basic Network Settings
To change the engine IP address, as well as basic network settings such as
hostname and SNMP configuration (including system contact, system location,
trap server, SNMP trap community string, SNMP user, SNMP authentication, and
SNMP privacy credentials), enter the following command at the login prompt in
the Console tab:
/usr/postinstall/nacconfig
This will start the network configuration script and allow you to make the desired
changes.
