Use the command "switchport mode trunk" on the interfaces connecting the two devices to together. A trunk interface by default will allow all VLANs (from 1-4094) to pass traffic over it, you can limit which ones can go across, I would recommend you do, but look that up loater.
Now, between the two switches you need to have an 802.1q trunk interface. The on the 3750 configure the layer 3 part of the VLAN (the VLAN)ĭo this ont he 3750 for all the VLANs you have configured at layer 2.ĭo this for the other interfaces and VLANs as required. Unless you use VLAN Trunking Protocol (VTP), I very much recommend you don't!, you will need to create the layer 2 LVAN on both switches. Http:/ / networking-topics/ vlan-networks/ 222-intervlan-routing.html Http:/ / c/ en/ us/ support/ docs/ lan-switching/ inter-vlan-routing/ 41860-howto-元-intervlanrouting.html Here's some guides, it's very straight forward once oyu get oyu head around it! Once you then apply the different VLANs to the access interfaces they will be able to communicate with the other VLANs by sending the traffic to the default gateway (the SVI) of it's VLAN and to the other host inteh other VLAN via that VLANs SVI. Ideally you will have a core switch which is where to configure the layer 2 VLAN and the Switched Virtual Interfaced (SVI, making it a layer 3 VLAN) with an IP address, then trunk down to the access layer switches.Īll that needs to be configured on the access layer is the layer 2 VLANs. Have you set up an 802.1q trunk link between the two switches or are they routed (IP address at each end of the link between them)? PS: please, I'd appreciate simplified explanations and laymen terms. I prefer to delete it globally, then re-create correctly, with your help and assign IPv4 subnets. It was something within the VLAN config itself that I couldn't figure out. As soon as I moved the ethernet cable to another existing VLAN, worked fine. Issue I've had before is setting up on some supposedly deleted VLANs such as #9.
