Description
Expansion Module Performance
The N2K-C2248PR Cisco Nexus 2248pq 10 GE Expansion Module is designed to extend the capabilities of Cisco Nexus 2000 Series Fabric Extenders, providing high-density 10 Gigabit Ethernet (GE) connectivity to servers and storage devices.
The performance of the N2K-C2248PR expansion module is based on several key features:
- Port density: The module provides 48 10 Gigabit Ethernet ports, allowing for high-density connectivity in a compact form factor. This enables efficient use of rack space and reduces cabling requirements.
- Power over Ethernet Plus (PoE+): The module supports PoE+ on all 48 ports, delivering up to 30 watts of power per port. This enables the module to power devices such as IP phones, wireless access points, and security cameras, simplifying cabling and reducing power consumption.
- High availability: The module supports virtual PortChannel (vPC) technology, which allows for redundant connections to upstream switches, providing high availability and load balancing.
- Low latency: The module has low latency, enabling high-performance applications such as database transactions and video streaming.
- Flexible configuration: The module can be configured in either access or fabric extender (FEX) mode, allowing for flexible deployment in various network architectures.
Power Management Features
The N2K-C2248PR Cisco Nexus 2248pq 10 GE Expansion Module is a high-performance data center switch that offers advanced power management features to help optimize power usage and reduce energy costs. Here are some of the power management features of this module:
- Energy Efficient Ethernet (EEE): EEE is a networking standard that reduces power consumption during periods of low traffic by automatically adjusting the power level of Ethernet ports. The N2K-C2248PR supports EEE, which can significantly reduce power consumption during periods of low network activity.
- Power supply redundancy: The N2K-C2248PR features two power supplies for redundancy. If one power supply fails, the other can automatically take over, ensuring uninterrupted operation and avoiding downtime.
- Power over Ethernet (PoE) support: The module supports PoE, which allows it to provide power to connected devices such as IP phones, cameras, and access points through Ethernet cables, eliminating the need for separate power supplies.
- Power management through Cisco EnergyWise: The N2K-C2248PR supports Cisco EnergyWise, a powerful energy management solution that allows network administrators to monitor and control power usage across the network. With EnergyWise, administrators can set policies that govern how devices use power, helping to reduce energy waste and lower costs.
- Port power management: The module supports port power management, which allows administrators to control the power usage of individual ports. This can be useful in situations where certain ports are not being used or are only used intermittently, as power can be allocated more efficiently to other devices.
Security Features
The N2K-C2248PR Cisco Nexus 2248pq 10 GE Expansion Module is a data center switch designed to provide high-performance networking solutions. It is equipped with several security features that enhance the security of the network. Here are some of the security features of the N2K-C2248PR:
- Port Security: The N2K-C2248PR has a port security feature that allows the administrator to restrict the number of MAC addresses that can be learned on a specific port. This helps prevent unauthorized access to the network.
- VLAN ACLs: The N2K-C2248PR supports VLAN access control lists (ACLs) that allow the administrator to restrict traffic to specific VLANs based on specific criteria such as IP addresses or port numbers.
- DHCP Snooping: DHCP snooping is a feature that helps prevent rogue DHCP servers from assigning IP addresses to clients. The N2K-C2248PR supports DHCP snooping, which enables the switch to monitor DHCP traffic and prevent unauthorized DHCP servers from being used.
- Dynamic ARP Inspection: The N2K-C2248PR supports dynamic ARP inspection, which verifies ARP packets against the DHCP snooping database. This helps prevent ARP spoofing attacks that can be used to steal network information.
- MACsec: The N2K-C2248PR supports MACsec, which is an encryption standard used to secure traffic between devices. MACsec can be used to secure traffic between the switch and other network devices, ensuring that all data transmitted over the network is encrypted and secure.
- Role-Based Access Control (RBAC): The N2K-C2248PR supports RBAC, which enables the administrator to control access to the network based on the user’s role or job function. This helps prevent unauthorized access to the network and ensures that users only have access to the resources they need.
