Note: Network Time Protocol (NTP) is the protocol used to
synchronize the attached computer's date and time data with a
referenced NTP server. When CC-SG is configured with NTP, it can
synchronize its clock time with the publicly available NTP reference
server to maintain correct and consistent time.
3. Click Update Configuration to apply the time and date changes to
CC-SG.
4. Click Refresh to reload the new server time in the Current Time field.
5. Choose System Maintenance > Restart to restart CC-SG.
Connection Modes: Direct and Proxy
About Connection Modes
CC-SG offers three connection modes for in-band and out-of-band
connections: Direct, Proxy, and Both.
• Direct mode allows you to connect to a node or port directly, without
passing data through CC-SG. Direct mode generally provides faster
connections.
• Proxy mode allows you to connect to a node or port by passing all data
through CC-SG. Proxy mode increases the load on your CC-SG
server, which may cause slower connections. However, Proxy mode
is recommended if you are more concerned about the security of the
connection. You need to keep only the CC-SG TCP ports (80, 443,
and 2400) open in your firewall. Proxy mode does not use SSL
between CC-SG and the KXII device for KVM data, when AES is
enabled in the KXII device.
• Both mode allows you to configure CC-SG to use a combination of
Direct mode and Proxy mode. In Both mode, Proxy mode is the default,
but you can configure CC-SG to use Direct mode when connections
are made using client IP addresses in specified ranges.
Important: When CC-SG is in Proxy or Both mode, you cannot give
users access to virtual media. Some interfaces only work in Direct
mode even though you configure CC-SG to use Proxy mode. These
interfaces include ILO, RDP, DRAC, Web Browser and VMware
Viewer. See About Interfaces (on page 72).
Configure Direct Mode for All Client Connections
To configure direct mode for all client connections:
1. Choose Administration > Configuration.
2. Click the Connection Mode tab.
3. Select Direct mode.
