   Physical Properties

   The following list provides details for some physical interface properties.
   • Data Link Layer protocol and keepalives: You can change the Data Link Layer protocol for the particular media type
   (for example, PPP to Cisco HDLC), and you can turn keepalives on or off.

   • Link mode: On Ethernet interfaces you can hardcode the duplex setting to either half-duplex or full-duplex.
   • Speed: You can specify the link speed on certain interface types.
   • Maximum transmission unit (MTU): You can vary the size from 256 to 9192 bytes.
   • Clocking: Refers to the interface clock source, either internal or external.
   • Scrambling: Refers to payload scrambling, which can be on or off.
   • Frame check sequence (FCS): You can modify to 32-bit mode (the default is 16-bit mode).
   • Diagnostic characteristics: You can enable local or remote loopbacks or set up a BERT test.

   Logical Properties

   The following list provides details for some logical interface properties:
   • Protocol family: Refers to the protocol family you want to use, such as family inet, inet6, iso, mpls, or
   ethernet-switching.
   • Addresses: Refers to the address associated with the particular family (for example, IP address using family inet).
   • Virtual circuits: Refers to the virtual circuit identifier, such as a data-link connection identifier (DLCI), virtual path
   identifier (VPI), virtual channel identifier (VCI), or virtual LAN (VLAN) tag.
   • Other characteristics: Some other configurable options include Inverse ARP, traps, and accounting profiles.
