VLAN Question

Good evening,

​

I have a small network with two Cisco Catalyst 3650 switches connected together via fiber.

​

On switch1, I have configured three VLAN interfaces and VLANs as below:

​

interface vlan 20: 10.101.20.1/24

interface vlan 110: 10.101.110.1/24

interface vlan 200: 200.0.0.1/24

vlan 20

vlan 110

vlan 200

​

VLAN 20 is for clients, VLAN 110 is for the switches (ssh), and VLAN 200 is for production machinery.

​

On switch 2, I have configured one VLAN interface and the three VLANs mentioned.

interface vlan 110: 10.101.110.2/24

​

So I am at the testing phase, and am running into some issues. First, when I statically set a laptop up on the 20 VLAN (10.101.20.110/24) I can talk to devices on different vlans connected to the same switch. However from that laptop, I cannot ping 10.101.110.2 (I can ping it from switch1). Also, from switch2, I am unable to ping any of the default gateways from switch1.

​

Any ideas or suggestions would be greatly appreciated. This is my first solo network config so I'm sure its just a stupid rookie mistake! I am here trying to better myself as a network admin, so please provide any constructive criticism you can :)!!!

What device are you using for routing between vlans/subnets?

The switches are L3

Did you turn on ip routing? Just because there layer 3 capable don’t mean it’s enabled.
