Hello I have a Cisco sf350 switch, we create a new vlan and detect on Linux Server on that vlan that we have a lot of BOOTP/DHCP message become from the switch.
07:29:12.423400 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 2c:57:41:73:91:21, length: 296
--> 2c:57:41:73:91:21 Cisco switch maccadress
How can I stop this ?
We look inside the switch and not have a dhcp request configured, have a static ip.
