Description
Performance and Scalability
The Cisco Nexus 2248TP-E is a fabric extender expansion module that provides 48 ports of Gigabit Ethernet connectivity to parent switches, such as the Nexus 5000, Nexus 6000, and Nexus 7000 series. It is designed to increase the number of ports available on these switches while maintaining a single point of management, reducing the complexity and cost of managing a large network.
Performance:
The Cisco Nexus 2248TP-E provides line-rate, low-latency performance for all 48 ports, with a throughput of up to 176 Gbps. This makes it ideal for use in high-bandwidth environments, such as data centers and server farms. The module also supports jumbo frames, which can improve network performance by reducing the number of packets that need to be transmitted.
Scalability:
The Cisco Nexus 2248TP-E is highly scalable, allowing network administrators to easily add or remove fabric extenders as needed. The module supports Cisco’s Virtual Port Channel (vPC) technology, which enables multiple physical links between the fabric extender and the parent switch to act as a single logical link. This provides higher bandwidth and redundancy, while also simplifying network management.
The module also supports Cisco’s Fabric Extender Technology (FEX), which allows up to 24 fabric extenders to be connected to a single parent switch, providing up to 1152 ports per switch. This greatly increases the scalability of the network, while still maintaining a single point of management.
In addition, the Cisco Nexus 2248TP-E supports advanced features such as Quality of Service (QoS), which allows administrators to prioritize traffic based on application requirements, and Cisco’s Data Center Bridging (DCB) technology, which provides a lossless Ethernet fabric for improved performance and reliability.
Port Density and Configuration Options
The N2K-C2248TR-E is a Cisco Nexus 2248TP-E Fabric Extender Expansion Module that provides additional port density and configuration options to a Cisco Nexus switch. Here are some key features and specifications of the N2K-C2248TR-E:
- Port Density: The N2K-C2248TR-E provides 48 ports of 100/1000BASE-T with four 10 Gigabit Ethernet (GE) fabric interfaces.
- Configuration Options: The N2K-C2248TR-E can be configured as a standalone device or as part of a larger Cisco Nexus fabric. It supports a range of Cisco features such as Virtual PortChannel (vPC), FabricPath, and Cisco Data Center VM-FEX.
- Fabric Extender Technology: The N2K-C2248TR-E uses Cisco Fabric Extender (FEX) technology to extend the capabilities of a Cisco Nexus switch. This allows the module to be managed as a remote line card of the parent switch, which simplifies management and reduces the need for additional cabling.
- High Performance: The N2K-C2248TR-E provides line-rate performance for all ports, with low latency and jitter.
- Energy Efficiency: The N2K-C2248TR-E is designed to be energy-efficient, with support for Energy-Efficient Ethernet (EEE) and Cisco EnergyWise.
Quality of Service (QoS) Features and Capabilities
The N2K-C2248TR-E Cisco Nexus 2248TP-E 48 Ports Fabric Extender Expansion Module is a high-performance and flexible fabric extender that provides a range of Quality of Service (QoS) features and capabilities to ensure the delivery of reliable and efficient networking services.
Here are some of the QoS features and capabilities of the N2K-C2248TR-E:
- Traffic Classification: The N2K-C2248TR-E supports various traffic classification mechanisms such as Layer 2 (L2), Layer 3 (L3), and Access Control List (ACL) based classification to prioritize traffic based on specific criteria.
- Traffic Prioritization: The module supports the Differentiated Services Code Point (DSCP) and Class of Service (CoS) mechanisms to prioritize traffic and ensure that high-priority traffic is delivered first.
- Traffic Policing: The N2K-C2248TR-E can control the amount of traffic sent or received by a particular port or VLAN by enforcing a specific rate limit.
- Traffic Shaping: The module can control the rate of traffic sent or received by a particular port or VLAN to ensure that the traffic meets the required service level.
- Congestion Management: The N2K-C2248TR-E supports various congestion management mechanisms such as Weighted Random Early Detection (WRED), and Tail Drop to avoid congestion and ensure that the network operates at an optimal level.
- Link-level Flow Control: The module supports the IEEE 802.3x flow control mechanism to manage the flow of traffic between devices and avoid congestion in the network.
- Priority Flow Control (PFC): The N2K-C2248TR-E supports PFC, which is an IEEE standard that allows for the lossless delivery of traffic for specific classes of service.
