I am trying to create a SVI on a catalyst 3750 switch but when I do a show int vlan , it indicates the line protocol is down.What could ve the problem and how do I get it up?

Here is my config:

Switch#vlan database

Switch(vlan)#vlan 700 name Management

Switch(vlan)#exit

...

...

Switch#conf t

Switch(config)#int vlan 700

Switch(config-if)#ip address 172.16.1.1 255.255.255.0

Switch(config-if)# no shut

Switch(config-if)#^z

Hello,

Try enabling "ip routing" in global configuration mode.

Hi,

Just see whether the interface is up. Until u assign this vlan to some particular port, line protocol will be down!

Try by assigning this vlan to some active port, it will show the line protocol as UP!

Hope this will help!

Hi Friend,

It will remain in line down state till the time you ceate any active port for that vlan.

Suppose you craete SVI for vlan 700 you have to assign any physical port to that vlan or else create a trunk port and allow that vlan on that trunl and the line protocl will come up.

So in short any SVI should have a physical port assignment or there should be an active trunk for that vlan.

HTH, if yes please rate the post.
