Configuring Authentication for the Controller and NTP Server
To obtain CDP debug information for the controller using the controller CLI, follow these steps:
Step 1 Obtain debug information related to CDP packets by entering by entering this command:
debug cdp packets
Step 2 Obtain debug information related to CDP events by entering this command:
debug cdp events
Configuring Authentication for the Controller and NTP Server
Starting in release 7.0.116.0, the controller software is now compliant with RFC 1305. As per this
requirement, controllers must synhronize time with an NTP server by authentication. By default, an
MD5 checksum is used.
Using the GUI to Configure the NTP Server for Authentication
To configure NTP Server Authentication using the controller GUI, follow these steps:
Step 1 Choose Controller > NTP > Severs to open the NTP Severs page.
Step 2 Click New to add a new NTP Server.
Step 3 In the Server Index (Priority) text box, enter the NTP server index.
The controller tries Index 1 first, then Index 2 through 3, in a descending order. Set this to 1 if your
network is using only one NTP server.
Step 4 Enter the server IP address in the Server IP Address field.
Step 5 Select the Enable NTP Authentication check box to enable NTP Authentication.
Step 6 Enter the Key index.
Step 7 Click Apply.
Using the CLI to Configure the NTP Server for Authentication
To configure NTP server authentication using the CLI, use the following commands:
• config time ntp auth enable server-index key-index—Enables NTP authentication on a given NTP
server.
• config time ntp key-auth addkey-index md5 key-format key—Adds an authentication key. By
default MD5 is used. The key format can be "ascii" or "hex".
• config time ntp key-auth delete key-index—Deletes authentication keys.
• config time ntp auth disable server-index—Disables NTP authentication.
• show ntp-keys—Displays the NTP authentication related parameter.
