Cisco Etherswitch Network Module

Cisco Etherswitch Network Module ... 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 combination of Cisco 2600, 3600 or 3700 Series 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 include 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.
