Configuring Date and Time
Riverbed recommends that you use NTP time synchronization for configuring the date and time.
To use Network Time Protocol (NTP) time synchronization
1. Choose Configure > System Settings > Date and Time to display the Date and Time page.
Figure: Date and Time Page
![](../shm_5.0_ug_html/images/configure_sys_set_date_time.png)
2. Under Date and Time, click Use NTP Time Synchronization.
3. As a best practice, you should configure your own internal NTP servers; however, if you want to use the Mobile Controller-provided NTP server, the hard-coded IP address that is preconfigured into every Mobile Controller is 208.70.196.25. This IP address appears in the NTP server list.
4. To add a new NTP server, complete the configuration as described in this table.
Control | Description |
Add a New NTP Server | Displays the controls to add a server. |
Hostname or IP Address | Specify the hostname or IP address for the NTP server. You can connect to an NTP public server pool; for example, 0.riverbed.pool.ntp.org. When you add an NTP server pool, the server is selected from a pool of time servers. |
Version | Select the NTP server version from the drop-down list: 3 or 4. |
Enabled/Disabled | Select Enabled from the drop-down list to connect to the NTP server. Select Disabled from the drop-down list to disconnect from the NTP server. |
Key ID | Specify the MD5 or SH1 key identifier to use to authenticate the NTP server. The valid range is from 1 to 65534. The key ID must appear on the trusted keys list. |
Add | Adds the NTP server to the server list. |
Remove Selected | Select the check box next to the name and click Remove Selected. |
5. Click Save to save your settings permanently.
Note: To modify server properties, select the server name in the server table row.
To set the time and date manually
1. Choose Configure > System Settings > Date and Time to display the Date and Time page.
2. Under Date and Time, click Set Time Manually.
3. Complete the configuration as described in this table.
Control | Description |
Time Zone | Select a time zone from the drop-down list. The default value is US/Pacific. Note: Changes to the Time Zone will end your current browser session and require you to log in again. |
Change Date | Specify the date in this format: yyyy/mm/dd. |
Change Time | Specify military time in this format: hh:mm:ss. |
4. Click Apply to apply your changes to the running configuration.
5. Click Save to save your settings permanently.
Note: After you apply your settings, you can verify whether changes have had the desired effect by reviewing related reports. After this verification, you can write the active configuration that is stored in memory to the active configuration file (or save it with any filename you choose). For details on saving configurations, see
Managing Configurations.
