Recommended DHCP Configurations for CC-SG 
Review the following recommended DHCP configurations. Make sure 
that your DHCP server is set up properly before you configure CC-SG to 
use DHCP. 
• 
Configure the DHCP to statically allocate CC-SG's IP address. 
• 
Configure the DHCP and DNS servers to automatically register the 
CC-SG with the DNS when the DHCP allocates an IP address to 
CC-SG. 
• 
Configure the DNS to accept un-authenticated Dynamic Domain 
Name System (DDNS) registration requests from CC-SG. 
 
Configuring Logging Activity 
You can configure CC-SG to report to external logging servers and 
specify what level of message is reported in each of the logs. 
 
To configure CC-SG logging activity: 
1.  Choose Administration > Configuration. 
2.  Click the Logs tab. 
3.  To assign an external log server for CC-SG to use, type the IP 
address in the Server Address field under Primary Server. 
4.  Click the Level to Forward drop-down arrow and select an event 
severity level. All events of this level or higher will be sent to the 
logging server. 
5.  To configure a second external log server, repeat steps 3 and 4 for 
the fields under Secondary Server. 
6.  Under CommandCenter Log, click the Level to Forward drop-down 
menu and select a severity level. All events of this level or higher will 
be reported in CC-SG's own internal log. 
7. Click 
Update 
Configuration to save your changes. 
 
Purge CC-SG's Internal Log 
You can purge the CC-SG's internal log. This operation does not delete 
any events recorded on your external log servers. 
Note: The Audit Trail and Error Log reports are based on CC-SG's 
internal log. If you purge CC-SG's internal log, these two reports will also 
be purged. You can also purge these reports individually. See 
Purge a 
report's data from CC-SG
 (on page 182). 
 
To purge CC-SG's internal log: 
1.  Choose Administration > Configuration.
