Table 3. Network Module Numbers and Descriptions
Product Number Product Description
C3KX-NM-1G Four GbE port network module
C3KX-NM-10G Two 10GbE SFP+ ports network module with four physical ports with two SFP+ and two regular SFP ports
C3KX-NM-10GT Two 10GB-T ports network module
C3KX-SM-10G Service Module with two 10GbE SFP+ ports network module for Netflow and MACsec encryption
The SFP+ interface supports both 10GbE and GbE port, allowing customers to use their investment in GbE SFP
and upgrade to 10GbE when business demands change, without having to do a comprehensive upgrade of the
access switch. The four uplink modules are hot swappable. The four network modules can be used in any of the
combinations shown in Table 4.

Service Module
The new Cisco Service Module offers enhanced 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. The new Cisco
Service Module enables the following services:
●
Line rate (40G) Flexible NetFlow for Network Monitoring and Security Anomaly Detection
Supported version 9
32,000 simultaneous flows
128 of simultaneous active monitors
●
Line rate (40G) MACsec encryption (please refer to MACsec section below)
FNF is a networking monitoring technology. A NetFlow table can be used to collect flow statistics. The flow
information can be used by customers for a variety of use cases like understanding:
1. Applications running on the network, and identify undesired applications, P2P etc
2. Granular Local and aggregated Campus view (Top N applications, drill down etc).
3. Top talkers (ports, users, applications) for application usage, productivity and asset utilization etc.
