DHCP broadcast mode
The DHCP broadcast mode configures the DHCP server to send DHCP request
responses as broadcast packets instead of unicast packets.
DHCP protocol
The DHCP protocol lets a host that is unknown to the network administrator
automatically access a new IP address for its network. The network administrator
allocates address pools in each subnet and enters them into the DHCP configuration
file.
DHCP server
The DHCP server provides automatic IP address and network configurations to
remote devices. For example, the DHCP server can provide dynamic IP address
information to a technician’s laptop.
DHCP server host
The DHCP server host is a host that is served by the DHCP server. It can access and
obtain IP address and network configurations from the server.
digital input
Digital inputs generate two events that reflect the state of the input: open and close.
disconnect mode
The disconnect mode is a handshake from a device attached to Remote RMM-1400
that terminates or accepts termination of an asynchronous connection.
discrete alarm
Digital discrete alarms are basic open or closed circuits where no data communication
is involved. Monitored devices have either a set of dry or wet contact closure outputs.
The outputs from the monitored devices are relay switches that close or open upon a
given alarm condition. They are called “dry” when the monitored device (a network
element) does not apply voltage to the alarm connection. They are called “wet” when
the monitored device applies voltage to the alarm connection.
