Configuring the switch DHCP server
The switch contains an internal Dynamic Host Configuration Protocol (DHCP) Server. DHCP can
provide the dynamic assignment of IP addresses automatically. DHCP is a protocol that includes
mechanisms for IP address allocation and delivery of host-specific configuration parameters from a
DHCP server to a host. Some of these parameters are IP address, network mask and gateway.
When a DHCP server allocates an address for a client, the client is assigned a lease (which expires
after an interval defined by the administrator). Before the lease expires, clients are expected to
renew the lease to continue to use the addresses assigned. Once a lease has expired, the client to
which that lease was assigned is no longer permitted to use the leased IP address.
NOTE
DHCP Server setting updates are only implemented when the switch is restarted.
NOTE
When using the switch’s internal DHCP server ensure that traffic can pass on UDP ports 67 & 68
between the switch and the the clients receiving DHCP information.
