DHCP IP address assignment
DHCP dynamically determines the network configuration of each Nortel
Call Recording Card. DHCP reduces the work necessary to administer an IP
network by using a server to allocate network addresses. DHCP also permits
automatic reuse of addresses by specifying a lease time. Clients must renew
the lease periodically.
The client (the Nortel Call Recording Card) first broadcasts a discover
message containing its Ethernet address as a client identifier. A DHCP
server replies with an offer message, containing configuration parameters.
The client can receive offers from multiple DHCP servers. The client must
select a server by broadcasting a request message containing the server
identifier. The server acknowledges the reply and assigns the configuration
to the client. The client can now use the assigned configuration.
The DHCP server assigns a reserved address to the card to guarantee that the
card always receives the same IP address. Otherwise, the card must have an
assigned DNS name to ensure it is always found using a Web browser. If the
local DHCP server provides long lease periods, this may not be necessary.
