DHCPD: Option 125 not present in the msg.

[Evlaa2021]

We have a problem with newer Cisco C9XXX series switches dropping option 125 for Mitel IP Phones. Mitel IP Phones use option 125 to configure the call server, TFTP server and various other network settings.

The switches are completely dropping the DHCP offers when recieved, as you can see from the output below, this means that the phones never recieve an IP Address. If i plug a laptop into the same network i recieve and IP address fine. If i statically set the call server and tftp server on the Mitel phone it also boots up correctly.

I have added the following dhcp relay commands, which i believed would not interfere with DHCP offers, or not recognised DHCP options;

ip dhcp relay information policy keep
ip dhcp relay information trust-all

Any ideas what could be causing this behaviour or ways to stop the switch dropping unknown DHCP options;

Hi Evan,

Do you have any luck dealing with this issue?

Best Regards
