thanks a lot for replying. I really appreciate that but how it will look like  i mean it will automatically detect by the switch or i have to make it active because i am depending on all my SFP connections. can i make them trunk or no swictch port for InterVlan routing. Like normaly we do,

# int ge0/0

#switch port mode ?

Awaiting your reply

Hi Oliver,

You have to configure interfaces for the kind of connection you want them to be. By default they will only have "no ip address" configuration. E.g. trunk interface:

Switch(config)# interface fastethernet 2/1 

Switch(config-if)# shutdown 

Switch(config-if)# switchport mode dynamic desirable 

Switch(config-if)# switchport trunk encapsulation dot1q 

Switch(config-if)# no shutdown 

Switch(config-if)# end 

Here is the guide for configuring L2 interfaces (including decription of modes - "switchport mode ..."):

If you want to make interface a L3 one, you have to enable routing globally ("ip routing"), configure "no switchport" on it and set up ip address:

Switch(config)# ip routing

Switch(config)# interface fastethernet 2/1

Switch(config-if)# no switchport

Switch(config-if)# ip address 10.1.1.1 255.255.255.248

Switch(config-if)# no shutdown

Switch(config-if)# end

Switch#

Here is the guide with more details on it:
