Cisco 8832 Administration Guide

Manually Set the Phone Date and Time
With certificate-based authentication, the phone must display the correct date and time. An authentication
server checks the phone date and time against the certificate expiry date. If the phone and the server dates and
times don't match, the phone stops working.
Use this procedure to manually set the date and time on the phone if the phone is not receiving the correct
information from your network.
Procedure
Step 1 From the phone administration web page, scroll to Date & Time.
Step 2 Perform one of the following options:
• Click Set Phone to Local Date & Time to synch the phone to a local server.
• In the Specify Date & Time fields, select the month, day, year, hour, minute, and second using the menus
and click Set Phone to Specific Date & Time.
SCEP Setup
Simple Certificate Enrollment Protocol (SCEP) is the standard for automatically provisioning and renewing
certificates. It avoids manual installation of certificates on your phones.
Configure the SCEP Product Specific Configuration Parameters
You must configure the following SCEP parameters on your phone web page
• RA IP address
• SHA-1 or SHA-256 fingerprint of the root CA certificate for the SCEP server
The Cisco IOS Registration Authority (RA) serves as a proxy to the SCEP server. The SCEP client on the
phone use the parameters that are downloaded from Cisco Unified Communication Manager. After you
configure the parameters, the phone sends a SCEP getcs request to the RA and the root CA certificate is
validated using the defined fingerprint.
Procedure
Step 1 From the Cisco Unified Communications Manager Administration, select Device > Phone.
Step 2 Locate the phone.
Step 3 Scroll to the Product Specific Configuration Layout area.
Step 4 Check the WLAN SCEP Server check box to activate the SCEP parameter.
Step 5 Check the WLAN Root CA Fingerprint (SHA256 or SHA1) check box to activate the SCEP QED parameter.
Simple Certificate Enrollment Protocol Server Support
If you are using a Simple Certificate Enrollment Protocol (SCEP) server, the server can automatically maintain
your user and server certificates. On the SCEP server, configure the SCEP Registration Agent (RA) to:
