R3303-HP HSR6800 Routers Interface Configuration Guide

29
For each channel set, the system automatically creates a serial interface named serial
interface-number:set-number. These interfaces are logically equivalent to synchronous serial interfaces
where you can make other configurations such as:
• Data link protocol such as PPP and FR
• IP addressing
