Created a Vlan but doesnt show in "Show Vlan" output

[John Stevens]

I created the following vlan on one of my cisco WS-C6504-E switches.

interface Vlan352

description SecurInfra

ip address 10.14.36.2 255.255.255.0

ip helper-address 172.17.40.40

ip flow ingress

ip flow egress

shutdown

When i do a no shutdown and type "show vlan" to see the list, it is not listed?

This switch is in VTP server mode, so i was able to create it no problem.

am i over looking something?

Thanks

What you have showed us is about the layer 3 SVI interface vlan 352. You have created this at layer 3. You have not shown us anything that shows that you created the layer 2 vlan.  Is it possible that you are confused about the relationship of interface vlan 352 which is layer 2 and of vlan 352 which is layer 2?

Note that the show vlan command is looking for the layer 2 vlan and not the layer 3 interface vlan 352.

You have to add an entry to the vlan database to see them in "show vlan" output.

conf terf

vlan 352

exit

show vlan

Hope it helps
