3.4 Description of the actions
The priorities have the following effect for the synchronization of the DHCP server:
● MASTER: The computer node is defined as master, i.e. the computer becomes the active
● HIGH: The computer node belongs to the server candidates with high priority, i.e. if no
● LOW: The computer node belongs to the server candidates with low priority, i.e. if no
Note
Recommended settings are:
• DHCP operation and DHCP synchronization are switched on in the system network.
• Exactly one NCU is set as DHCP master.
• Maximum of two computers are candidates with "HIGH" priority.
• All other components are set as DHCP clients or candidates with "LOW" priority.

Mode of operation
This command opens a port in the firewall to the company network (X130) for a certain time.
The default time is 15 minutes, but this can be changed with the -MINUTES option. The
maximum possible time is 60 minutes.
The port to be opened is specified in the form "PROTO/PORTNR". The protocol can be
either "tcp" or "udp". This is followed by the specification of the hosts from which the port
should be accessible. Several forms are possible here:
● A single IP address: "128.128.12.12"
● A host name (if this can be resolved via DNS), e.g. "server"
● An IP area with network screen form specification, e.g. "128.128.12.0/255.255.255.0"
● An IP area with specification of the valid bits, e.g. "128.128.12.0/24"
