address, the Cayman 3220-H selects another address and repeats the
sequence until it finds an address that is not in use.
Dynamic allocation of IP addresses means that an IP address can be
reused when it is not longer needed by the client to which it is
assigned. Dynamic IP address allocation is particularly useful in
situations where clients connect to a network temporarily or where
a site needs to share a limited pool of IP addresses among a group of
clients that do not need permanent IP addresses.
The Cayman 3220-H is configured at the factory to act as a DHCP
client on its WAN port. This means that, if substitute IP address
information is not configured for the WAN port, the Cayman 3220-H
will send a DHCP broadcast message asking for configuration
information from any available DCHP server. If a DHCP server is
active on the network connected to the WAN port, the Cayman
3220-H will accept and use the network configuration settings the
DCHP server provides to configure the Ethernet settings for the WAN
port.
The Point-to-Point Protocol (PPP) is a set of network protocols that
enables you to connect TCP/IP hosts and networks over serial
telephone connections. Extensions to the PPP protocol suite enable
a PPP link to support other network protocols, including IPX,
AppleTalk, and DECnet.
The nodes at each end of a PPP link are referred to as peers. Unlike
client-server networks, where one device is responsible for
providing services to another, peer-to-peer networks function as
equals, providing services to one another as needed.
PPP provides a standard method of encapsulating network protocol
information over point-to-point links. PPP also defines a Link Control
Protocol (LCP), which provides for link configuration, peer
authentication, and link quality monitoring. Finally, PPP includes
