Some intervlan routing is not working on 3560 while others work

I've create interface vlan 150 with an ip address, then no shut.
I then connected the devices for that vlan on the switchports with the proper vlan configured and the vlan is in the vlan database.
The devices can ping each other but the devices on the other vlans cannot ping the devices from vlan 150.
The other devices on other vlans can ping other inter-vlan devices but not this specific one I just created.

The 3560 can ping all devices from every different vlans including the vlan 150 just created.

Any ideas on why routing is not working for vlan 150?

What do you get on switch when you type this:


show int vlan150

show vlan


Can you post also

show run int vlan150


If you have trunk ports, did you define which VLANs are allowed to pass the trafiic or you allow them all (switchport mode trunk) ?

Can you ping 192.168.150.1 from your client or client outside of VLAN 150?

Are all of your clients on the same switch or is it connected to other switches?

When you ping from interface, is 192.168.0.19 IP of the interface or is this a client? When you try to ping from interface, put interface IP as a source IP on the switch.

What is set as default gateway for VLAN 150 on your hosts in that VLAN?
That should be IP address of your interface VLAN 150.

Are clients using 'this' 3560's SVIs as their default-gateway?

Got a maintenance window and rebooted the router. All is good now.

Nothing else made sense.  When in doubt reboot.
