I would like assistance with the parameterization of a Cisco SG200-18 switch. Indeed I would like to create three separate VLANs to distribute from the internet to three companies that do not have to interact in it or with my personal network, I successfully created these three vlan, I limited the flow on the 3 Ports I wish to register with these three companies (1 port per company with 1 reserved network address) and thus have three separate network addresses for these three companies but I can not go further in the procedure.When I try to Change the subnet mask of the switch the interface gele ....
I give you some information about my network: ip address of the switch = 192.168.1.253 mask = 255.255.255.0. Ip address of my router = 192.168.1.254
Network address of my network = 192.168.1.0 mask = 255.255.255.0 (which can not be parameterized)
Could you guide me in this setting please.
In advance thank you to you I leave you my email address and my tel number for your information phone number = 06.44.97.28.13 mail = [email protected]
