I am having an issue with routing on my 3750 switch. I turned on routing with the "ip routing" command and confirmed it was enable by doing a "show run" command. I then created several VLAN's and assigned each of them an IP address and subnet mask. I then assigned the appropriate interfaces to the desired vlans. I did put in the "show vlan brief" command to confirm that the interfaces were in the correct VLAN's. At this point, I took a few workstations and assigned them a static IP in the same subnet as the VLANs they were attached too but I was unable to ping anything. When I ran the "show ip interface brief" command I saw all but one vlan read status up but protocol down. I am stumped and to why this occurred. I am hoping this is something simple that I overlooked. Any assistance or suggestions would be very appreciated.
If you only ever show one vlan then you do not have layer 3 running on the switch. In layer 2 you will only have 1 native vlan. If you continue to change VLAN's then the last VLAN you created will be the VLAN shown.
