To enable remote management by a Secure Computing Central Management Server,
check Enable Central Management.
In IP Address of CMS, enter the IP address of the host on which Secure Computing
CMS is running.
Specify the shared Authentication Key with which to authenticates this device against
the CMS. This must be the same as the snmp_community configuration setting for CMS.
It should be something hard to guess.
When configured for centralised management, the device periodically sends a "ping"
(SNMP trap) back to the CMS to indicate that it is alive. Back-to-base ping interval (s)
specifies the interval in seconds between these pings. This must be less than the
max_alive_interval configuration setting for CMS.
Specify the Local SNMP Port on which the management agent listens for requests.
