New Vlan on our main switch but cannot use any of the IP addresses in that Vlan

Beth_Dierks — Fri, 09 Feb 2018 21:25:00 GMT

I have created a new Vlan on our main switch and can ping the Vlan's gateway from all areas but if we try to use an IP address from that Vlan it will not work. Any ideas on what needs to be fixed?

Hello Beth,

This could be a couple of things. What is not working? Can you please elaborate on the problem?

Is ping what you're expecting to work with these new IPs? What device(s) are on this new VLAN? Did you add other ports to the VLAN so that these devices have connectivity?

We added this Vlan with 254 usable IP addresses. The gateway is 116.1 and this we are able to ping successfully from any of our edge switches and or devices we are trying to connect. So we were trying to use 116.9 with subnet of 255.255.255.0 and then the 116.1 gateway but it never connects.

Can you ping the gateway from the 116.9 device? If you would please respond with the "show vlan" output.

Yes if I run CMD I can ping the gateway from that device

Has ipforwarding been enabled? This will allow the switch to route traffic outside the VLAN.

This is from our main core switch:

configure vlan v116 ipaddress 10.128.116.1 255.255.255.0
enable ipforwarding vlan v116

Can you send me a "show vlan" and "show iproute" output?

What IP address are you trying to ping?

If I ping a device that is currently configured to 116.2 I get nothing back even on the switch:

I just figured this one out. I feel really stupid

now you have to tell us what the solution was

RE: New Vlan on our main switch but cannot use any of the IP addresses in that Vlan

Patrick_Voss — Sat, 10 Feb 2018 02:11:00 GMT

How do you know it is not connecting? What test are you using?

Beth_Dierks — Sat, 10 Feb 2018 02:14:00 GMT

I don't want too 🙂

Most of our equipment out on the shopfloor is configure to the 114Vlan, I never updated the port on the edge switch to reflect the 116Vlan!!!! Ugh
