Purpose
Enters interface configuration mode for the indicated port on the specified
ATM SPA.
(Required in back-to-back router configuration) Configures the interface for
internal clocking.
The default clocking on all ATM interfaces is line clocking, or retrieval of
the clock signal from the receive data stream. Therefore, you must configure
an internal clock when the ATM link is in back-to-back configuration between
two routers. In this case, one end of the link must be configured to use the
internal clock.
You do not need to configure clocking when the router is connected to a
switch, which also uses line clocking by default.
Integrated Local Management Interface (ILMI) is not supported on ATM
SPAs on the Cisco ASR 1000 Series Aggregation Services Routers. This
command is the default for all ATM SPAs on the Cisco ASR 1000 Series
Aggregation Services Routers.
(Optional) Assigns an arbitrary string, up to 80 characters long, to the
interface. This string can identify the purpose or owner of the interface, or
any other information that might be useful for monitoring and troubleshooting.
Enables the interface.
Exits interface configuration mode and returns to privileged EXEC mode.
