Description
Security Features and Capabilities
The N2K-C2248TR-E Cisco Nexus 2248TP-E 48 Ports Fabric Extender Expansion Module is a network module that provides connectivity for up to 48 Ethernet devices. It is designed to work with the Cisco Nexus series of switches and provides additional ports for expanding the network.
In terms of security features and capabilities, the N2K-C2248TR-E provides the following:
- Port Security: The module supports IEEE 802.1x port-based authentication, which allows only authorized devices to connect to the network. This feature helps to prevent unauthorized access and ensures that only trusted devices are allowed on the network.
- Access Control: The module supports access control lists (ACLs) which allows administrators to filter traffic based on specific criteria such as source and destination IP addresses, protocols, and ports. This feature helps to prevent unauthorized access to the network and helps to prevent denial of service attacks.
- VLAN Support: The module supports virtual LANs (VLANs) which allows administrators to group network devices into logical groups. This feature provides enhanced security by allowing administrators to segment the network and limit access to sensitive data.
- Secure Management: The module provides secure management interfaces such as SSH, HTTPS, and SNMPv3. These interfaces provide secure communication channels between the module and the management console, ensuring that sensitive data is not intercepted or compromised.
- Role-Based Access Control: The module supports role-based access control (RBAC), which allows administrators to assign different access levels to different users based on their roles and responsibilities. This feature provides enhanced security by limiting access to sensitive network resources.
- Security Logging: The module provides security logging capabilities, which allows administrators to track and monitor security-related events. This feature helps to detect and respond to security incidents in a timely manner.
Management and Monitoring Options
The Cisco Nexus 2248TP-E Fabric Extender is a 1RU expansion module that provides 48 Gigabit Ethernet ports with support for IEEE 802.1Q VLANs. It is designed to connect to a parent switch, such as the Cisco Nexus 5000 or 7000 series switches, to expand the switch’s port density.
Management Options:
- Cisco NX-OS Software: The Cisco Nexus 2248TP-E Fabric Extender runs on the same operating system as the parent switch, the Cisco NX-OS software. This allows for consistent management of both the parent switch and the fabric extender through a single management interface.
- Cisco DCNM: The Cisco Data Center Network Manager (DCNM) is a management platform that can be used to manage the Cisco Nexus 2248TP-E Fabric Extender. It provides a GUI-based interface for provisioning, configuring, and monitoring the fabric extender.
- CLI: The Cisco Nexus 2248TP-E Fabric Extender can also be managed through the command-line interface (CLI) using the same commands as the parent switch.
Monitoring Options:
- Cisco DCNM: In addition to management, Cisco DCNM can also be used to monitor the Cisco Nexus 2248TP-E Fabric Extender. It provides real-time monitoring of port status, performance metrics, and alerts for events such as link failures or congestion.
- SNMP: The Cisco Nexus 2248TP-E Fabric Extender supports SNMP (Simple Network Management Protocol) for monitoring and reporting on device status and performance metrics.
- Syslog: The fabric extender can generate syslog messages that can be used for monitoring and troubleshooting. These messages can be forwarded to a central syslog server for analysis.
- SPAN: The Switched Port Analyzer (SPAN) feature allows for the monitoring of traffic on one or more ports on the fabric extender. This can be useful for troubleshooting or analyzing network traffic.
Scalable and Reliable
The N2K-C2248TR-E Cisco Nexus 2248TP-E 48 Ports Fabric Extender Expansion Module is a networking device that can be used to expand the number of ports on a Cisco Nexus switch. The expansion module connects to the switch using a high-speed fabric interface, and it provides an additional 48 Gigabit Ethernet ports for connecting devices to the network.
Scalability: One of the main advantages of the N2K-C2248TR-E expansion module is its scalability. With 48 additional ports, it can help businesses to expand their network without having to purchase an entirely new switch. This can save money and make it easier to manage the network, as all the devices can be connected to a single switch. Moreover, the expansion module can be easily added to the network as per the business requirements, which makes it easier for businesses to scale up or down their network.
Reliability: The N2K-C2248TR-E expansion module is designed to be reliable and to provide high availability. The module includes redundant hot-swappable power supplies and fans, which can help to ensure that the device continues to function even if one of the components fails. Additionally, the module supports features like Virtual PortChannels (vPCs) and FabricPath, which can help to improve network resiliency and reduce downtime.
