Wed Aug 31, 2022 7:20 am

hi there,

we have the configuration such as follow :
internet--- rb4011 ---- crs326-24G-2S+ ---- APs ----- clients
no vlans, but there is dhcp-snooping config active on crs-326-24G-2s+

recently we receive the following message on crs:
07:08:05 interface,warning ether15: received DHCP server message on untrusted port 
07:08:05 interface,warning ether15: received DHCP server message on untrusted port

07:54:56 interface,warning ether15: received DHCP server message on untrusted port 
08:02:37 interface,warning ether11: received DHCP server message on untrusted port 
what we need is the detail of the suspected of the mention rouge dhcp. i already add interface, dhcp, debug on /system logging but no details received.

is there any idea how to get the detail info ? such as mac and or ip addres of the source rouge dhcp ?

thank you
