Card type Preprovisioning
When installing a VWIC2-2MFT-T1/E1 card, you must provision what the card will do before configuring it. With this particular card, you could provision it as a T1, E1 or PRI depending on the clients requirements. The card command is used to accomplish this.
Prior to provisioning, a show run outputs the following:
boot-start-marker boot-end-marker ! ! card type command needed for slot/vwic-slot 0/0 ! card type command needed for slot/vwic-slot 0/1 ! card type command needed for slot/vwic-slot 0/2 logging buffered 51200 warnings !
It’s easy to see there is a problem. In addition to the errors in the configuration, no controllers or serial interfaces are seen. In our scenario, we needed to configure this card as a T1 so we issued the following command:
router(config)# card type T1 0 0 router(config)# card type T1 0 1 router(config)# card type T1 0 2
The numbers at the end of the command specify your slot and subslot. After issuing these commands, we can see that the T1 controllers are now present in the running configuration:
controller T1 0/0/0 cablelength long 0db ! controller T1 0/0/1 cablelength long 0db ! controller T1 0/1/0 cablelength long 0db ! controller T1 0/1/1 cablelength long 0db ! controller T1 0/2/0 cablelength long 0db ! controller T1 0/2/1 cablelength long 0db
Now that the controllers are created and we look at the running configuration, we still can’t see any serial interfaces. This is because being a multiflex card, we have to create the appropriate channel-group or pri-group. We are termianting a T1 so we will issue the following command under the controller:
router(config-controller)# channel-group 0 timeslots 1-24
After this command is issued, a new serial interface is created that is available for configuration. You have successfully configured the VWIC2-2MFT-T1/E1!
