SESM and SSG Performance

Packets sent between the SSG and the SESM might require processing by the Cisco 10000 router Route Processor (RP), instead of the parallel express forwarding (PXF) engine.

The following conditions require RP processing of packets:

•When the SESM interface is connected to the network management (NME) port of the performance routing engine (PRE, Part Number ESR-PRE2), all traffic between the SSG and the SESM is passed to the RP for processing.

•When the SESM is connected to one of the line card interfaces and the Port-Bundle Host Key feature is configured on the SSG, all packets sent to and from the SESM are passed to the RP for processing.

•When the SESM is connected to one of the line card interfaces and TCP redirect is enabled, all TCP packets from the SESM to the SSG are passed to the RP for processing.

Note The RP does not have as much forwarding capacity as the PXF.
