Cisco - Cisco EtherSwitch Modules for the 2600/3600/3700 Series Routers

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.

The combination of Cisco 2600, 3600 or 3700 Series routers and the EtherSwitch modules utilize the powerful features available in both Cisco IOS^Ž 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 inline power 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.

The Cisco 16- and 36-port EtherSwitch modules are available with optional inline power and Gigabit Ethernet support. EtherSwitch bundles are available with these options pre-installed for easy ordering. The inline power 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 3700 Series.

Options

•

GE-DCARD-ESW-This optional 1000BaseT Gigabit Ethernet port for NM-16ESW and NMD-36-ESW can be used for a gigabit connection for a file server or in the future could be used for intra-chassis stacking of the Cisco EtherSwitch module. Stacking is not supported at this time, but this feature will be available in a future supported in Cisco IOS release 12.2(11)T.

•

PPWR-PS-CHASSIS—The power chassis is an external chassis that can support up to four 360W power supplies, which can provide inline phone power. This chassis can support up to 144 IP phones @ 10W per port (or less devices at <10W per port). Also available is a custom cable that connects the power supply to the Cisco EtherSwitch Modules. Cable options allowing for power supply redundancy are also available. The inline power works over standard Category 5 unshielded twisted-pair (UTP) cable up to 100 meters and allows direct power instead of using wall power with a transformer. This allows customers to use existing Category 5 UTP installations. The Cisco EtherSwitch Module inline power implementation passes the required U.S. and international safety regulations and compliance measures.

•

NM-16ESW-PWR and NMD-36ESW-PWR—The 16- and 36-port Ethernet switch modules with power daughter cards support 48V inline power of IP telephones when either purchased with an external power chassis or when used with an internal power supply. This combination of components enables IP phones to be plugged into any EtherSwitch module port. Also, the integrated inline power for the 10/100BaseTX autosensing ports provides DC power to devices that can accept power over traditional UTP cabling (such as the Cisco 7900 Family of IP phones). This allows a standard RJ-45 jack to be powered from this EtherSwitch module source rather than having a separate plug into an AC wall outlet. Delivery of -48V power must be made to the 16-port Ethernet switch. This daughter card is required for inline power. A power supply is also required.

•

PPWR-PS-360W—This single 360W power supply for the Cisco EtherSwitch module line power can be added to a power chassis or can added internally into the Cisco 3700 Series router to power additional IP phones or wireless access points. Each power supply supplies up to 360W and can power up to 36 IP phones.

Example Solutions

Small Branch Data Only

A Cisco EtherSwitch Network Module in a branch data deployment provides the flexibility of integrated routing and switching functions in one unit for low port densities. This deployment provides high-speed connections between individual desktops, servers, and other network resources in a single unit for Layer 2 and allows WAN connection at Layer 3 through the router. The Cisco EtherSwitch NM and Cisco 2600 router also provide an ideal solution for Cisco 2505, 2507, and 2516 users whose requirements have expanded beyond the existing Cisco 2500 Router/hub capabilities.

Typical Deployment: Small Branch Data and IP Phones using Cisco 2600 and 3600 Series Routers

Small Branch Data and IP Phones

The Cisco EtherSwitch Network Module combined with analog or digital voice modules for the Cisco 2600 and 3600 routers provide a small branch office infrastructure for IP Telephony deployments. This solution can be combined with Cisco CallManager IP Telephony and the Cisco IOS Survivable Remote Site Telephony (SRS Telephony) solution. SRS Telephony runs on the local branch office router allowing it to automatically detect a failure in the network, and initiates a process to intelligently auto-configure the router to provide call-processing backup redundancy for the IP phones in that office.

The Cisco EtherSwitch NM with the external power chassis provides IP Phone power and phone discovery for IP phones. In addition, the Cisco EtherSwitch NM supports automatic VLAN configuration for IP Phones. The auxiliary VLAN feature allows network administrators to segment phones into separate logical networks even though the data and voice infrastructures are physically the same. The phone discovery allows the EtherSwitch NM-16ESW-PWR to automatically detect the presence of an IP phone and supplies inline power.

Cisco 3600 Series http://www.cisco.com/warp/public/cc/pd/rt/3600/prodlit/index.shtml

Small Branch Data and IP Phones with 3700 Series

In this example we maintain all the features of Figure 4 above but we have now used the internal IP Phone Power capabilities from the Cisco 3700 series and added the 36-port EtherSwitch HDSM. The Cisco EtherSwitch HDSM combined with analog or digital voice modules for the Cisco 3700 routers provide a small branch office infrastructure for IP Telephony deployments at a higher port density. This solution can also be combined with Cisco CallManager IP Telephony and the Cisco IOS Survivable Remote Site Telephony (SRS Telephony) solution.

Data Communications Networks (DCN)

Another unique application of the Cisco EtherSwitch NM with Cisco 2600/3600 routers is in a Cisco DCN (Data Communications Network) operations and facilities management solution. The Cisco DCN solution can be deployed using Cisco routers and Catalyst switches and delivers an out-of-band network used by service providers and large enterprises for managing their primary network. By integrating the routing and switching functionality into one form factor, service providers and enterprises can achieve a cost-effective solution for their facilities management, monitoring and billing applications. The benefit is the reduction in valuable floorspace use as well as the advantages of reduced management, maintenance and training costs.
