How to properly configure vlan on cisco?

Question

Mikrotik

Help me please. There is a microtic, a wire goes from it to 1 cisco port, the port is in trunk mode, all other ports are in different vlans. The problem is that PCs do not receive ip, traffic does not go through 1 port

Answer 1

With a standard config on cisco, it is enough for the port to be a trunk and a vlan to be created on the switch. If you allow specific vlans on the trunk, then do not forget to allow those vlans that you need. If with such settings it doesn’t work for you, then perhaps your config is not standard or there is a config problem on the Mikrotik side

Answer 2

Good evening. You need to clarify the question a little if your network gateway is Mikrotik and the switch is Cisco. You will first need to decide how you will be routing vlans, the easiest way to RoS. In Mikrotik, you will need to create the appropriate subinterfaces with the necessary vlan encapsulation. And in the Cisco trunk port, you will need to specify the necessary vlans. You also need to clarify about the dhcp server, how is it organized for you? If on Mikrotik, then IP addresses will be issued without problems, if, say, on Windows servers, then you will need to add the ip helper address of this server (this command is for Cisco, for Mikrotik you need to look.)
