MFR (FRF16) Overhead details:

==============================

Fragment 1:

Fragmentaion header : 2 bytes

Framerelay header : 2 bytes

Inner proto : 2 bytes

HDLC flag and FCS : 4 bytes

Fragments 2 ...n :

Fragmentaion header : 2 bytes

Framerelay header : 2 bytes

HDLC flag and FCS : 4 bytes

Overhead with LFI

MLPPP(Long & short sequence):

============================

Outer PPP header : 4 bytes

HDLC flag and FCS : 4 bytes

MLFR (FRF15):

=============

Framerelay header : 2 bytes

Control,NLPID : 2 bytes

HDLC flag and FCS : 4 bytes

The following examples show overhead for different cases:

• A 1000-byte packet is sent to a mlppp bundle without any fragmentation. At the

Layer 2 level, bytes transmitted is 1013 in 1 packet. This overhead is for MLPPP long

sequence encap.

• A 1000-byte packet is sent to a mlppp bundle with a fragment threshold of

250byte. At the Layer 2 level, bytes transmitted is 1061 bytes in 5 packets.

• A 1000-byte LFI packet is sent to an mlppp bundle. At the Layer 2 level, bytes

transmitted is 1008 in 1 packet.

remaining-traffic—(Optional) Display the queuing statistics of all logical interfaces that

do not have traffic-control profiles configured. (Not on the QFX Series.)

Additional Information For rate-limited interfaces hosted on Modular Interface Cards (MICs), Modular Port

Concentrators (MPCs), or Enhanced Queuing DPCs, rate-limit packet-drop operations

occur before packets are queued for transmission scheduling. For such interfaces, the

statistics for queued traffic do not include the packets that have already been dropped

due to rate limiting, and consequently the displayed statistics for queued traffic are the

same as the displayed statistics for transmitted traffic.
