The egress datapath shapers on a 6-port SAR-M Ethernet module operate on the same frame size as any other shaper. These egress datapath shapers are:
per-queue shapers
per-SAP aggregate shapers
per-customer aggregate (MSS) shapers
The egress port shaper on a 6-port SAR-M Ethernet module does not account for the 4-byte FCS. Packet byte offset can be used to make adjustments to match the desired operational rate or eliminate the implications of FCS. See Packet Byte Offset (PBO) for more information.
