ZTP with KEA for Huawei switches
Hi ISC Support,
In the context of using KEA DHCP for ZTP of Huawei Switches, we’re right now facing an issue within the implementation of RFC Compliance within KEA DHCP.
Based on the documentation of Huawei (see https://support.huawei.com/enterprise/en/doc/EDOC0100533703?section=j004) the Switch Firmware is relying on the overlapping Options 141 + 146 (see https://kea.readthedocs.io/en/latest/arm/dhcp4-srv.html#id2) which are conflicting in terms of DHCP Option Type.
We would therefore kindly ask ISC to review this issue, as it’s entirely blocking the introduction of ZTP / Autoconfiguration of Huawei Switches within our installation base.
In case no solution exists out of the box, we would further ask ISC to consider a compatibility option for allowing the override of standard RFC-ed options, see e.g. https://kea.readthedocs.io/en/latest/arm/dhcp4-srv.html#kea-dhcpv4-compatibility-configuration-parameters
