Shutting Down and Restarting an Interface on a SPA
Shutting down an interface puts it into the administratively down mode and takes it offline, stopping all
traffic that is passing through the interface. Shutting down an interface, though, does not change the
interface configuration.
As a general rule, you do not need to shut down an interface if you are removing it and replacing it with
the same exact model of SPA in an online insertion and removal (OIR) operation. However, we
recommend shutting down an interface whenever you are performing one of the following tasks:
•
•
•
•
•
•
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.

Note
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.
To shut down an interface, perform the following procedure beginning in global configuration mode:

When you do not need to use the interface in the network.
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.
