Switch Module Features Overview

The CBS3120X switch module supports both the Cisco X2 transceiver modules and the Cisco TwinGig Converter Module. The CBS3120G switch module supports only the Cisco TwinGig Converter Module. See the “10-Gigabit Ethernet Module Slots” section on page 1-4for more information.

For more information about the features of each model, see the hardware installation guide and the software configuration guide for the switch module. See the release notes and the software configuration guide for information about supported Layer 3 features.

See Table 1-1for more detailed descriptions of the switch module ports.
