Cisco ASR 1000 Series Software Configuration Guide

•
Preparing for future testing or troubleshooting.
•
Changing the interface configuration in a way that would affect the traffic flow, such as changing the
encapsulation.
•
Changing the interface cables.
•
Removing a SPA that you do not expect to replace.
•
Replacing an interface card with a different model of card.
Shutting down the interface in these situations prevents anomalies from occurring when you reinstall the new
card or cables. It also reduces the number of error messages and system messages that might otherwise appear.
If you plan to replace an existing ATM port adapter with an ATM SPA in the Cisco ASR 1000 Series
Router and want to use the same configuration, save the slot’s configuration before physically replacing
the hardware. This is because all slot configuration is lost when you replace one card type with another
card type, even if the two cards are functionally equivalent. You can then re-enter the previous configuration
after you have inserted the ATM SPA.
Note
To shut down an interface, perform the following procedure beginning in global configuration mode:
SUMMARY STEPS
1.
Router(config)# interface atm slot/subslot/port
2.
Router(config-if)# shutdown
3.
Router(config-if)# end
DETAILED STEPS
PurposeCommand or Action

the specified ATM SPA.
Router(config)# interface atm slot/subslot/port
Step 1
Shuts down the interface.Router(config-if)# shutdown
Step 2
Exits interface configuration mode and returns to privileged
EXEC mode.
Router(config-if)# end
Step 3
What to Do Next
When you shut down an interface, the show interface command indicates that the interface is
administratively down until the SPA is physically removed from the chassis or until the SPA is re-enabled.
Tip
The following shows a typical example of shutting down an ATM SPA interface:
