This lesson will show you how to configure VLANs on a Cisco Small Business series switch. In my example, I’m using an SG 300-10MP switch, but it will be similar to other SMB switches. In the example below we have a single switch connected to 4 devices, each device is in a different VLAN. To accomplish this we need to create those VLANs and assign the interfaces to the correct VLAN.
First, we need to login to the switch, the default IP address is 192.168.1.1. The default username is ‘cisco’, and the password is also ‘cisco’.
Once you are logged in, you need to select VLAN Management from the menu and then choose Create VLAN:
In this overview, you will see all VLANs that this switch has at the moment. So far, there is only VLAN 1 (management VLAN). Hit the Create VLAN button:
Add VLAN 2,3, and 4 and give them a descriptive name. Your overview will look like this:
The VLANs are now configured, but we still have to assign our interfaces to the correct VLAN. Select VLAN Management and then Interface Settings:
You will see the following overview with all interfaces on the switch. As you can see, by default, all interfaces are trunks. We want to make sure that the interfaces connected to the different devices are access ports and that they can only access their own VLAN. Select an interface, and click on Edit:
Here’s an example of the GE1 interface. For the interface VLAN Mode, select Access and click on Apply:
Do the same for interface GE2, GE3, and GE4, so your overview looks like this:
Interface GE1, GE2, GE3, and GE4 are now in access mode, but we still need to select the VLAN that they belong to. Do this by selecting VLAN Management from the menu and then choosing Port VLAN Membership:
You will see the following overview with the Port VLAN Membership overview:
Select one of the interfaces and hit the Join VLAN button:
Make sure you select the correct VLAN for the interface and ensure that Tagging is set to Untagged. Configure GE2 for VLAN 2, GE3 for VLAN 3, and GE4 for VLAN 4. Once you are done, your overview will look like this:
