Initial Setup of the ProCurve NAC 800
System Settings
3. Select the Use a proxy server for Internet connections check box.
4. In the
Proxy server IP address
field, enter the address of the server that will
act as the proxy for the Internet.
5. In the Proxy server port field, enter the port for your proxy server.
The valid range is from 1 to 65535. Typically, you can accept the default
(8080).
6. If your proxy server requires authentication, select the
Proxy server is
authenticated check box. Then configure the authentication settings:
a. Select an option from the
Authentication method
drop-down menu:
– Basic —This method (the original for HTTP authentication) is not
recommended because it transmits the user ID and password in
plaintext. However, it is compatible with most proxy servers.
– Digest —This method, which is supported by HTTP 1.1-compliant
servers, is significantly more secure than basic authentication.
Instead of submitting the password over the network, the NAC
800 uses it to encrypt a random value.
–
Negotiable
—The NAC 800 and the proxy server agree together
whether to use basic or digest authentication. This option elimi-
nates compatibility issues, but is less secure than the digest
option.
b. In the
User name
field, enter the ID of a user account on the proxy
server.
c. In the
Password
field, enter the password of that user account.
d. Re-enter the password in the Re-enter password field.
7. When you are done editing MS settings, click the
ok
button to save the
changes.
Edit MS or CS Date and Time Settings. You now have two options for
configuring the MS date and time. The MS can receive its clock either:
■
Automatically from an NTP server
■
From the date and time that you set manually
Receiving the clock from an NTP server is generally the more reliable option.
The date and time settings configured for the MS apply to all ESs; however,
you can set the time zone individually for each ES.
