framing (10-Gigabit Ethernet Interfaces)

Syntax

Hierarchy Level

Description

For routers supporting the 10-Gigabit Ethernet interface, configure the framing format. WAN PHY mode is supported on MX240, MX480, MX960, T640, T1600,T4000, and PTX Series Packet Transport Routers routers only.

Note:

The T4000 Core Router supports only LAN PHY mode in Junos OS Release 12.1R1. Starting with Junos OS Release 12.1R2, WAN PHY mode is supported on the T4000 routers with the 12-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+ (PF-12XGE-SFPP). Starting with Junos OS Release 12.2, WAN PHY mode is supported on the T4000 routers with the 24-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+ (PF-24XGE-SFPP).
On PTX Series routers, WAN PHY mode is supported only on the 24-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+ .
When the PHY mode changes, interface traffic is disrupted because of port reinitialization.
In Junos OS Releases 17.4R2, 17.4R3, and later, on the following MPCs or routers, you cannot configure wan-phy mode at 10-Gbps, 40-Gbps, and 100-Gbps on a per-port basis:
- MPC7E-10G, MPC7E-MRATE, MX2K-MPC8E, and MX2K-MPC9E
- MPC10003
- MX204 router
- JNP10K-LC2101 MPC

Default

Operates in LAN PHY mode.

Options

lan-phy—10GBASE-R interface framing format that bypasses the WIS sublayer to directly stream block-encoded Ethernet frames on a 10-Gigabit Ethernet serial interface.

wan-phy—10GBASE-W interface framing format that allows 10-Gigabit Ethernet wide area links to use fiber-optic cables and SONET devices.

precise-bandwidth—Enables precise bandwidth for WAN-PHY interface framing format.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 8.0.

The option precise-bandwidth introduced in Junos OS Release 19.3R1 for MX Series Routers.
