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.

Data Sheet

The Cisco 16- and 36-port EtherSwitch modules are available with optional Cisco pre-standard Power over Ethernet
and Gigabit Ethernet support. EtherSwitch bundles are available with these options pre-installed for easy ordering. The
integrated power over ethenet supports Cisco IP phones and Cisco Aironet wireless access points. An external power
supply is needed for this feature in Cisco 2600/3600 platforms. An Internal power supply option is available on the
Cisco 2800, 2900, 3700, 3800 and 3900 Series. For 802.3af power over Ethernet support one of the newer
EtherSwitch Service Modules (NME-16ES-1G-P, NME-23ES-1G-P, NME-XD-48ES-2S-P, SM-ES2*-P family or SM­ES3*-P family) or one of the EtherSwitch HWICs (HWIC-4ESW-POE or HWIC-D-9ESW-POE) are recommended.

This 16-port version should be ordered only if you require Cisco pre-standard Power over Ethernet (POE). To take advantage of this
capability be sure to have or order an external power unit to support Power over Ethernet (POE) for the Cisco 2600 and 3600 or be
sure to order the internal power supply upgrade when using the EtherSwitch Network module in combination with the Cisco 2800,
3700,and 3800 Series.

Features and Benefits

Table 1. Features and Benefits of Cisco EtherSwitch Modules

Features Benefits

16/36 10BaseT/100BaseTX Ports Delivers up to 200 Mbps of bandwidth (full duplex) Layer 2; forwards and filters backflow at full wire speed

Autosensing on each port Detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps

Integrated Switching Provides fewer points of management for remote and small branch offices

Support for 802.1P QoS Supports QoS based on the Institute of Electrical and Electronics Engineers (IEEE) class-of-service (CoS)

802.1D Spanning Tree (a Layer 2

link-management protocol that

provides path redundancy while

preventing undesirable loops in the

network)

Voice Virtual LAN (VLAN) feature for

basis

creating a link between two devices implementing VLANs
Simplifies network configuration and improves fault tolerance
