The N2K-C2248TP is a Cisco Nexus 2000 Series Fabric Extender (FEX), which is a line card that can be deployed with Cisco Nexus 5000 and 7000 Series Switches to provide access-layer connectivity for end hosts, such as servers, storage devices, and other network equipment.
The N2K-C2248TP supports a range of protocols and standards to ensure interoperability with other network devices and to provide advanced networking features. Some of the key protocols and standards supported by the N2K-C2248TP are:
- Ethernet: The N2K-C2248TP supports Ethernet connectivity at speeds of up to 10 Gbps, enabling it to handle high-bandwidth applications.
- Fibre Channel over Ethernet (FCoE): FCoE is a protocol that allows Fibre Channel traffic to be carried over Ethernet networks. The N2K-C2248TP supports FCoE, enabling it to connect to Fibre Channel SANs and provide access to storage resources.
- Link Aggregation Control Protocol (LACP): LACP is a protocol used to bundle multiple physical links into a single logical link, providing increased bandwidth and redundancy. The N2K-C2248TP supports LACP, enabling it to form link aggregation groups with other network devices.
- Virtual PortChannel (vPC): vPC is a technology that allows multiple switches to be configured as a single logical switch, providing increased scalability and redundancy. The N2K-C2248TP supports vPC, enabling it to be deployed in vPC environments.
- IEEE 802.1Q VLAN tagging: VLAN tagging is a mechanism used to identify VLAN membership on Ethernet frames. The N2K-C2248TP supports IEEE 802.1Q VLAN tagging, enabling it to support multiple VLANs.
- Spanning Tree Protocol (STP): STP is a protocol used to prevent loops in network topologies. The N2K-C2248TP supports STP, enabling it to participate in loop prevention mechanisms.
- Quality of Service (QoS): QoS is a mechanism used to prioritize network traffic based on its importance. The N2K-C2248TP supports QoS, enabling it to prioritize traffic and provide better performance for critical applications.
The N2K-C2248TP is a Cisco Nexus 2000 Series Fabric Extender that provides unified fabric access to servers and other networked devices. It is designed to extend the Cisco Nexus switch fabric to the access layer of the network, providing a highly scalable and flexible architecture.
Installation of the N2K-C2248TP requires the following steps:
- Physically install the fabric extender into the rack and connect the power and network cables.
- Configure the uplink ports on the fabric extender to connect to the upstream switch. This can be done using the console port and a serial cable, or through a network connection using the Cisco Nexus 2000 Series Fabric Extender Management Interface (FEMI).
- Configure the fabric extender to recognize the upstream switch and establish connectivity. This involves configuring the uplink port channel, enabling the Fabric Extender (FEX) feature, and configuring the switch interface to support the FEX.
- Configure the downstream server-facing ports on the fabric extender. This can be done using the FEMI or the Cisco Nexus switch command-line interface (CLI). You can configure port channel groups, VLANs, and other network settings.
- Verify connectivity between the fabric extender and the upstream switch and between the fabric extender and the downstream servers.
The configuration of the N2K-C2248TP involves configuring the fabric extender to communicate with the upstream switch and to provide network connectivity to the downstream servers. This includes configuring the port channels, VLANs, and other network settings.
Configuration steps include:
- Configure the uplink port channel on the fabric extender to connect to the upstream switch.
- Enable the Fabric Extender (FEX) feature on the upstream switch.
- Configure the switch interface to support the FEX and to recognize the fabric extender.
- Configure the downstream server-facing ports on the fabric extender.
- Configure VLANs and other network settings on the fabric extender.
- Verify connectivity between the fabric extender and the upstream switch and between the fabric extender and the downstream servers.
The Cisco Nexus 2000 Series Fabric Extender is a line of devices that provides a low-latency, high-bandwidth connection between servers and switches in a data center environment. The N2K-C2248TP is a specific model of the Cisco Nexus 2000 Series Fabric Extender that is designed to provide management and monitoring capabilities for a data center network.
The N2K-C2248TP offers 48 100/1000BASE-T ports that can be used to connect servers and other devices to the network. The device also features four 10 Gigabit Ethernet (10GE) uplink ports that provide a high-speed connection to the data center network. Additionally, the N2K-C2248TP supports a variety of features that help to simplify network management and monitoring.
One key feature of the N2K-C2248TP is its support for Cisco Data Center Network Manager (DCNM), a web-based network management tool that allows network administrators to configure and monitor their data center networks from a single interface. DCNM provides a range of features, including automated device discovery, configuration management, and performance monitoring.
The N2K-C2248TP also supports Virtual PortChannel (vPC) technology, which allows two physical switches to be paired together to provide a single logical switch. This can help to increase network resiliency and reduce downtime.
In terms of monitoring capabilities, the N2K-C2248TP supports Cisco Nexus Data Broker, which provides a framework for capturing and analyzing network traffic. With Nexus Data Broker, network administrators can monitor and analyze network traffic in real-time, allowing them to quickly identify and troubleshoot any issues that arise.
