Automate VLAN Configuration through TCL

Question

I am looking to implement Automation to VLAN config:

ios_config - does not suit my automation because I need to have the user input VLAN name and VLAN number as well int VLAN and IP address subnet mask of SVI. Any other TCL function I can use to complete this script? Like this:

Enter VLAN ID:
Enter VLAN name:
Enter VLAN IP address:
Enter VLAN Subnet mask:

ios_config: "no shut"

You need to build a function/procedure (with commands) to achieve this:

• To write to screen/a channel, use: puts
• To read input or a single line from screen/a channel, use: gets
• To retrieve a value from a variable, use: $
• To run a Cisco IOS configuration command, use: ios_config

The following simple procedure/script asks you to enter a VLAN ID and its name, then it will configure that VLAN on your device:

//Configure your TCL procedure:

#tclsh
(tcl)#proc Vlanconfig {} { 
+>puts "Enter VLAN ID: " ; 
+>gets stdin VLANid 
+>puts "Enter VLAN Name:" ; 
+>gets stdin VLANname
+>ios_config "vlan $VLANid" "name $VLANname" "end"
+>}
(tcl)#


//Run your procedure:

(tcl)#Vlanconfig
Enter VLAN ID: 
200
Enter VLAN Name:
Users

(tcl)#tclquit
#show vlan
VLAN Name                             Status
...
200  Users                            active
...

You can expand this procedure to configure L3 Int VLAN and its IP address as you what.

I hope it is helpful and you have an idea of how to build your own TCL procedure.
