Understanding Ethernet Interfaces for PTX Series Packet Transport Routers

PTX Series Packet Transport Routers are a portfolio of high-performance platforms designed for the service provider supercore. A PTX Series Packet Transport Router working in conjunction with a T Series core router allows a service provider to build a core network that is flexible enough to accommodate cloud-delivered services, mobility for devices and users, and bandwidth-intensive applications such as HD video. Forwarding architecture for PTX Series Packet Transport Routers is focused on MPLS and Ethernet.

All physical interfaces on a PTX Series Packet Transport Router use et for the FPC type. For information about how to specify interfaces, see these topics:

Note: Physical interfaces on PTX Series Packet Transport Routers do not support:

  • VLAN rewrite for CCC encapsulation
  • Source MAC learning for accounting
  • MAC policing

Note: Wide Area Network Physical Layer Device (WAN PHY) mode is supported on the 24-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+ (model number P1-PTX-24-10G-W-SFPP). No other PIC supports WAN PHY on the PTX router.
