Understanding Ethernet Interfaces for PTX Series Packet Transport Switches

PTX Series Packet Transport Switches are a portfolio of high-performance platforms designed for the service provider supercore. A PTX Series Packet Transport Switch 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 Switches is focused on MPLS and Ethernet.

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

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

  • VLAN rewrite for CCC encapsulation
  • Source MAC learning for accounting
  • MAC policing
  • Wide Area Network Physical Layer Device (WAN PHY) mode on the 24-port 10-Gigabit Ethernet PIC
