The new Cisco Service Module offers enhaced security and Flexible Netflow (FNF) features on the uplink ports of the Catalyst 3750-X and 3560-X. The service module is supported with IP Base or IP Services feature set. It can be used with SFP or SFP+ at 1G or 10G speeds. The new Cisco Service Module has custom dedicated hardware for FNF monitoring, separate from the dedicated hardware for MACSec. Therefore there is no impact on packet forwarding performance & latency. It offers flexibility with the user being able to define flows.
