The Cisco 16- and 36-port 10/100 EtherSwitch modules for Cisco 2600, 3600, and 3700 series routers offer branch office customers the option to integrate switching and routing in one platform. Combining robust Layer 3 flexible WAN routing with low-density line-rate Layer 2 switching, the EtherSwitch modules provide straightforward configuration, easy deployment and integrated management in a single platform.
The EtherSwitch options include a 16-port network module (NM) and a 36-port high density service module (HDSM) version. The 36-port HDSM utilizes the extra capacity from the wider interface form factor available only on the Cisco 3700 and Cisco 3660 routers to increase the port densities. The 16-port EtherSwitch NM is available for the Cisco 2600, 3600 and 3700 series routers.
