Cisco N2K-C2148T-1GE Cisco Introduces Nexus 2000 Series Fabric Extender Architecture and Nexus 2148T Fabric Extender Product The Cisco Nexus 2148T forwards all traffic to parent Cisco Nexus 5000 Series Switches over 10 Gigabit Ethernet uplinks. Depending on the number of server ports and uplinks used, the Cisco Nexus 2148T FEX can support oversubscription ratios ranging from 1:1 to 4.8:1. Passing all traffic to the parent switch allows all traffic to be shaped according to policies established on the Cisco Nexus 5000 Series switch with a single point of management.The Cisco Nexus 2000 Series Fabric Extenders integrate with the parent switch, allowing zero-touch provisioning as well as automatic configuration and software upgrade when the fabric extender is connected to the parent switch. This integration allows large numbers of servers to be supported with the same feature set as the parent Cisco Nexus 5000 Series switch and with specific configuration parameters including security and quality of service (QoS). The FEX does not run Spanning Tree Protocol even when multiple links are connected to the parent switch, thus giving customers loop-free, active-active connectivity between the two.No software is included with the Cisco Nexus 2148T. Software is downloaded from the parent Nexus 5000 Series switch.

Availability

The Cisco Nexus 2148T will be available for ordering and first customer shipment (FCS) in the first quarter of 2009.
