Installing HP Device Manager
Configuring Routers 33
Configuring a Linux
DHCP Server
1 Edit the DHCP server configuration file /etc/dhcpd.conf. Add
the following lines to the beginning of the file exactly as shown:
ddns-update-style ad-hoc;
Authoritative;
Option NDM code 201 =string;
Option vendor-class-identifier “PXEClient”;
Option NDM “‘Management_Gateway_IP_Address’ ‘40003’”;
2 Restart dhcpd to use the new configuration.
3 The HP Device Manager config string should be:
‘Management_Gateway_IP_Address’ ‘40003’
Configuring Routers
For PXE to function properly, any network that uses DHCP and has
multiple subnets should have an IP helper configured in the router
between any clients requiring a dynamic IP address and the DHCP
server. The router will need to be configured to have an additional IP
helper address to point to the Management Gateway.
Example (Cisco Router):
1 Go to Global Configuration mode.
2 Type ip forward-protocol udp 67 and press Enter.
3 Type ip forward-protocol udp 68 and press Enter.
4 Go to the LAN interface(s) that serves the PXE workstations.
5 Type ip helper-address <DHCP Server IP address> and press
Enter.
6 Type ip helper-address <Management Gateway IP address>
and press Enter.
Note: The above IP addresses should be entered without the < or >
characters.
