Changing the ES Network Settings
CAUTION:
Back up your system immediately after changing the MS or ES IP address. If
you do not back up with the new IP address, and later restore your system, it
will restore the previous IP address which can show an ES error condition
and cause authentication problems. See “Maintenance” on page 3-105 for
instructions on backing up and restoring your system.
To change the ES network settings:
Home window>>System configuration>>Enforcement clusters &
servers>>Select an ES>>Configuration
Modify any of the following Network settings you want to change:
■
Enter a new ES in the Host name text field. For example,
garp.mycompany.com
■ Enter a new ES address in the
IP address
text field. For example,
192.168.153.35
■
Enter a new netmask in the Network mask text field. For example,
255.255.255.0
■ Enter a new gateway in the
Gateway IP address
text field. For example
192.168.153.2
■
Enter one or more DNS resolver IP addresses, separated by commas,
semicolons, or spaces in the
DNS IP addresses
text box. For example:
10.0.16.100,10.0.1.1
NOTE:
The NAC 800 ESs host name must be a fully qualified domain name (FQDN).
For example, the FQDN should include the host and the domain name—
including the top-level domain.
For example, waldo.mycompany.com. Select names that are short, easy to
remember, have no spaces or underscores, and the first and last character
cannot be a dash (-).
NOTE:
You cannot change the ES IP address for a single-server installation. You can
change the MS IP address for a single-server installation.
