Just reminder for you Manik
1. Some of product cisco, especially that can use E1/T1 port. You must define what card type do you want to use. Example, when you insert module VWIC-2MFT, the card will detect (you can see at show inventory), but you cannot use this until you choose the card type. In show ip int brief, you cannot see the interface too. At show run, you will see command that said you must activate the card type E1/T1. To activate them, please use this command at config-terminal:
command : card type E1
command : card type T1
To verify, you can use command show run and show ip int brief.
2. Some of product cisco, you must define the media type (RJ45/SFP). The default is use RJ45. if you want to use SFP, you must change the media type. To activate them, please use this command at interface-config terminal:
command : media type sfp
command : media type rj45
To verify, you can use show run or show interface
3. You must remember this Manik. You usually forget about this command.
command : no switchport
command : ip routing
without this, you cannot do routing and add ip address in interface. REMEMBER!!
