To use TFTP instead of FTP for Polycom IP301 on DHCP:
- Login to the system shell as a root user
- Execute 'nano /etc/dhcpd.conf'
- At the beginning of the file, add the following line:
option boot-server code 66 = string;
Assuming that 'dhcpd' is running on 192.168.1.1. System running on 192.168.1.10. DHCP range is 192.168.1.120 - 192.168.1.150. NTP running on 192.168.1.1. Dhcp.conf should look like this:
option boot-server code 66 = string;
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option domain-name "yourdomainname.com";
option domain-name-servers 192.168.1.1;
option time-offset -25200; # Mountain Standard, -18000 EST, 3600/hr
option ntp-servers 192.168.1.1;
range 192.168.1.120 192.168.1.150;
group { # group phones together so only they get boot server info
option boot-server "tftp://polycom:[email protected]";
}}
- Press 'CTRL + O'
- Press 'CTRL + X'
- Execute '/etc/rc.d/init.d/dhcp restart'
Now when the phone boots it will contact the DHCP server and get its IP address, subnet, time server, gateway, and boot server information. It will then contact the boot server to download its configuration.
