Configuring the JUNOS Software to Enable an M160 Router to Operate in Packet Scheduling Mode

By default, packet scheduling is disabled on M160 Routers. To configure a router to operate in packet-scheduling mode, include the packet-scheduling statement at the [edit chassis] hierarchy level:

[edit chassis]packet-scheduling;

To explicitly disable the packet-scheduling statement, include the no-packet-scheduling statement at the [edit chassis] hierarchy level:

[edit chassis]no-packet-scheduling;

When you enable packet-scheduling mode, the Packet Director application-specific integrated circuit (ASIC) schedules packet dispatches to compensate for transport delay differences. This preserves the interpacket gaps as the packets are distributed from the Packet Director ASIC to the Packet Forwarding Engine.

Whenever you change the configuration for packet-scheduling, the system stops all SFMs and FPCs and restarts them in the new mode.

Note: Packet scheduling is for M160 routers only.
