Simplest configuration imaginable doesn't work. What am I missing?

Well, I'm new to managed switches, but have worked with unmanaged switches and standalone routers for many years. I'm trying to do the simplest imaginable thing on a test switch, and it fails. I've created a routed VLAN with four ports, assigned the VLAN a network address of 192.168.60.1/24, and when I attach a laptop (manually configured as 192.168.60.5, gw= ~60.1), I can't ping the gateway! What in the heck am I not getting? 

 

As an aside, what I would like to do eventually is set up several VLANS that cannot see one another's traffic, making them private, while giving all VLANS access to an Internet router on its own VLAN. Looks like I'm going to have a steep learning curve.

 

Here's my simple configuration, consisting of two VLANs, VLAN15 and VLAN60. VLAN 15 has an address of 192.168.15.20. On that VLAN is an Internet router addressed as 192.168.15.1. I'd like a device plugged into VLAN60 to have Internet access, but not access to any other VLAN.

 

At the moment, I can't ping the addresses for either VLAN. All ports are marked as untagged. The configuration is shown below.

 

Thanks for helping a newbie!

Re: Simplest configuration imaginable doesn't work. What am I missing?

Hi @Tim_In_VA 

 

Welcome to Community!

 

I notice there is 3 static route in the startup-config file, I'm afraid it's the root cause.

Could you please remove the second and third one, only keep the default route(ip route 0.0.0.0/0 192.168.15.1), then try again.

 

!
ip route 0.0.0.0/0 192.168.15.1
ip route 192.168.15.0/24 192.168.15.1
ip route 192.168.60.0/24 192.168.15.1
!

 

Beside:

Could you please check the route table from the Router, if there is back route to VLAN60 IP subnet(ip route 192.168.60.0/24 192.168.15.20)?

 

Hope it helps!

 

Regards,

EricZ
