Packet Over SONET (POS) Interfaces
POS Interfaces are supported on E-Series TeraScale e
t
platforms
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.
• VRRP is not supported on POS interfaces.
• A POS interface cannot be configured as part of a LAG.
