Tektronix Phaser 840 setup guide Supported BOOTP/DHCP fields, Dhcp transactions

Setting the Printer’s IP Addressing Parameters 8

DHCP transactions

■On power up or reset, the printer sends a DHCP discover packet, indicating its Ethernet address and requesting an IP address.

■The DHCP server responds to the discover packet with a DHCP offer packet, which contains an IP address from within the assigned scope and the assigned lease.

■The printer examines the DHCP offer packet and decides whether to accept the lease. The printer sends a request packet, accepting the IP address and the lease.

N O T E

There can be multiple DHCP servers on the same network, each defining its own scopes and leases. The printer selects the first lease offered.

■The DHCP server sends an acknowledgment packet to the printer, which completes the transaction.
