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:
• Physical Part of an Interface Name
• Logical Part of an Interface Name
•
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
