Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
The
au
command enables you to begin configuring the interface in the AU controller configuration mode,
where you can configure tributary unit groups (TUGs), virtual containers (VCs), and DS3s, such as shown in
the following path example:
STM-1 -> AU-4 -> TUG-3 -> VC-3 -> DS-3
One AU-4 path is equivalent to three AU-3 paths. An administrative unit type 4 (AU-4) consists of three STM-1s
or one STM-3. An administrative unit type 3 (AU-3) consists of one STM-1.
Use the
au
command to configure one of the AUGs available for your card. The
au
command is not used
to configure the
type
of AU path that you are configuring, such as AU-3 or AU-4, but rather is used to
identify one AU group number in the supported range for the card and AU type that you are configuring.
For example, the 1-Port Channelized OC-48/STM-16 SPA supports 16 AU-4 groups. Therefore, you can
specify a number between 1 and 16 for the
au
command to configure SDH AU-4 on that card.
