Packet Over SONET (POS) Interfaces
POS Interfaces are supported on E-Series TeraScale
Important Points to Remember
•
PPP encapsulation must be configured before the interface is enabled for traffic.
•
An IP address must be configured on an interface. POS line cards do not operate in Layer2 mode.
•
SONET alarm reporting cannot be disabled.
•
SONET uses synchronous transport signal (STS) framing. Configure framing only when the interface
is shut down.
•
The POS scramble-atm, C2 and J0 flags, and alarm reporting is supported.
•
The following features are not supported:
•
The E-300 chassis does not support POS line cards.
