16- and 36-Port 10/100 Ethernet Modules for Cisco 2600/2800/2900/3600/3700/3800/3900 Series Routers

Figure 1. Cisco 16-Port and 36-Port EtherSwitch Network Modules

The Cisco 16- and 36-port 10/100 EtherSwitch modules for Cisco Integrated Services Routers 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

2851, 3660, 3700, and 3800 series routers to increase the maximum possible port densities. The 16-port EtherSwitch

NM is available for the Cisco 2600, 2800, 3600, 3700, 3800, 2900 and 3900 series routers.

The combination of Cisco Integrated Services Routers and the EtherSwitch modules utilize the powerful features

available in both Cisco IOS

software and Catalyst switching. The EtherSwitch module hardware supports 802.1p

Layer 2 prioritization, while Cisco IOS software supports Layer 3 DiffServ and Class of Service (CoS) markings for

critical business data. Coupling Layer 2/3 prioritization techniques, with the QoS for the WAN, this integrated routing

and switching combination ensures low latency for critical business applications. The Cisco EtherSwitch modules

includes 10/100 switched Ethernet ports with options for Cisco pre-standard power over ethernet and Gigabit Ethernet.

Features such as port autosensing, QoS and VLAN support from 802.1p and 802.1Q standards, and 802.1D Spanning

Tree protocols are standard on the EtherSwitch modules.
