Configuring Channelized SONET/SDH on the Cisco ASR 9000 Series Router
Purpose
Enters global configuration mode.
Enters SONET controller configuration submode and specifies the
SONET controller name and interface-path-id with the
rack/slot/module/port notation.
Configures the SONET port transmit clock source, where the
internal keyword sets the internal clock and the line keyword sets
the clock recovered from the line.
Use the line keyword whenever clocking is derived from the
•
network. Use the internal keyword when two routers are
connected back to back or over fiber for which no clocking is
available.
• line is the default keyword.
Note Internal clocking is required for SRP interfaces.
Configures the controller for Synchronous Digital Hierarchy
(SDH) framing.
SONET framing (sonet) is the default.
Specifies the administrative unit (AU) group and enters AU path
configuration mode. For AU-4, the valid range is:
1 to 16—1-Port Channelized OC-48/DS3 SPA
•
1 to 3—1-Port Channelized OC-3/STM-1 SPA
•
1 to 4—2-Port Channelized OC-12c/DS0 SPA
•
The au command does not specify the AU type. It specifies
Note
the number of the AU group for the AU type that you want
to configure. The range for the AU command varies based
on whether you are configuring AU-3 or AU-4.
