DHCP Server
The switch can operate as either:
• DHCP client that obtains its own IP from a DHCP server, as described in
"DHCP IPv4 Interface" on page 214
• DHCP server that allocates IP addresses to other devices, as described in
this section

DHCP Server Overview
A DHCP server uses a defined pool of IP addresses (user-defined) from which
it allocates IP addresses to DHCP clients.
The DHCP server can allocate IP addresses in the following modes:
•
Static Allocation
— The hardware address of a host is manually mapped
to an IP address.
•
Permanent Allocation
— An IP address sent to the client through a
standard request-reply mechanism, is owned by that client permanently
(unless changes in the network environment/connections take place, for
any reason).
•
Dynamic Allocation
— A client obtains a leased IP address for a specified
period of time. The IP address is revoked at the end of this period, and the
client must request another IP address.
