How can a vlan be in a down down state?



also, the vlan subnet is not showing up in the show ip route command.  Any ideals?

Did you create the vlan on the switch, or just create the interface?

do:
show vlan brief

Open in new window

and see if Vlan2 shows up.

If not, you need to create (name) the vlan:

#config t
(config)#vlan 2
(config-vlan)#name myvlan
(config-vlan)#end
#

Open in new window


That will create the vlan and should allow the interface to up/up.

I got the int partially up.  Why is the method TFTP?  Shouldn't it be NVRAM?  And the subnet is still not showing up in the routing table.

Method TFTP means that the interface was configured from TFTP
Method NVRAM means that the interface was configured from a saved config loaded on boot
Method manual means that you manually configured the interface.

I would assume that your switch attempted autoconfiguration on boot via TFTP.

On the up/down status, try this:
#config t
(config)#int vlan 2
(config-if)#no shut
(config-if)#end
#sh ip int brief

Open in new window


See if it comes up/up.
