Question

How many Layer 3 and Layer 2 policers are supported on Juniper Networks MX Series devices?

Answer

The Layer 3 interface policer limit for I-chip-based DPCs is 39,000 possible, with 16,000 tested. In most implementations, logical interface limits are reached per port and per Packet Forwarding Engine before policer limits are reached.

 

The MX Series DPCs support Layer 2 policers indirectly. The Layer 2 policers are supported in the IQ2 Ethernet Services Engine, and the I-chip supports both Layer 3 and Layer 2 policing. The type of policing applied by the I-chip (Layer 3 or Layer 2) depends on the type of packet. For example, if a Layer 2 packet is received on a device using an I-chip, Layer 2 policing is performed by the I-chip.
