Using secondary ip-helper address for DHCP

Mobotix_IT — Wed, 13 Apr 2022 08:50:07 GMT

Hi,

is it possible to use a secondary ip helper address on a virtual interface to configure a secondary DHCP - Server address for redundancy?

Thank you and regards.

Yes, but both helpers will receive copies of all DHCP requests, so the servers will have to coordinate between themselves to decide which one will respond.

Ok is the syntax the same for the secondary address or do I have to add secondary at the end like configuring the secondary gateway.

The syntax is the same; check the Command Reference guide for the firmware version you are using.
