Configuring Physical Interface Properties

The software driver for each network media type sets reasonable default values for general interface properties, such as the interface’s maximum transmission unit (MTU) size, receive and transmit leaky bucket properties, link operational mode, and clock source.

This chapter discusses configuration of the following physical interface properties:

• Physical Interface Configuration Statements
• Physical Interfaces Properties Statements List
• Specifying an Aggregated Interface
• Specifying a USB Modem Interface on J-series Routers
• Specifying OC768-over-OC192 Mode
• Adding an Interface Description to the Configuration
• Configuring the Link Characteristics
• Configuring the Media MTU
• Configuring Interface Encapsulation on Physical Interfaces
• Configuring the PPP Challenge Handshake Authentication Protocol
