CRS DHCP snooping

RouterOS General

Hi

We are installing quite a few CRS switches into a complex, then from there either cat6 or fibre to the end users where they would have their own device such as a Mikrotik hap ac.
The end users would run their own dhcp servers for their own internal networks.

Question is, does the crs switches support DHCP snooping. i.e can I block all ports on the CRS switches from allowing dhcp broadcasts? Often an end user would fiddle around and plug his/her lan cable into another ethernet and there would be dhcp broadcasting around the layer2 network.

Thanks!

CRS does not support DHCP snooping, but if the only thing you need is to protect from a rogue DHCP server you can use protocol level isolation for that. Check out the following link for a configuration example: http://wiki.mikrotik.com/wiki/Manual:CRS_examples.
