The following set of commands configure the address pool and the network subnet IP address mask:
Use the following commands to configure the DHCP Mode, base Hostname and the network’s Domain Name:

6-12CHAPTER 6: MANUAL SETUP

IP Address Pool, Start and End address

IP Subnet address mask

Lease period

WINS Server addresses

￿DNS Server addresses

The Hostname is the base name assigned to the workstation . A numeric suffix is appended to the base name and incremented after each assignment. For example, if the Hostname unit is configured, the first workstation will be assigned the Hostname unit01, the second workstation will be assigned unit02 and so forth.

￿set dhcp mode server

set dhcp server hostname <host name> set dhcp server domain <domain name>

The DHCP address pool is configured by specifying the starting and ending addresses of the pool. The range of the pool must be 40 addresses or less and must be entered on the same command line.

￿set dhcp server start_address <ip address> end_address <ip address> set dhcp server mask <ip address>

The final set of DHCP Server commands configure the Lease period and IP addresses of the Default gateway, WINS Servers, and DNS Servers. There can be up to two WINS and DNS Servers specified. If this functionality is to be disabled, an IP address of 0.0.0.0 is entered. If the OfficeConnect Remote 812 is functioning as the DNS Proxy, the OfficeConnect Remote 812’s LAN IP address should be configured as the first (primary) DNS address.

set dhcp server lease <seconds> set dhcp server router <ip address>

set dhcp server wins1 <ip address> wins2 <ip address> set dhcp server dns1 <ip address> dns2 <ip address>

Monitoring the DHCP There are monitoring commands which display the DHCP protocol counters and Server current lease information. The DHCP protocol counters indicate the requests

received, responses transmitted, and error indicators. The lease information indicates which IP addresses have been assigned, the corresponding workstation MAC addresses, and remaining time before the lease expires.
