Features and Benefits
The N7K-M148GS-11L Cisco Nexus 7000 Series 48 Ports Gigabit Ethernet I/O Module provides several features and benefits that make it an ideal choice for data center networking. Here are some of the key features and benefits of the module:
- High port density: The module provides 48 ports of Gigabit Ethernet connectivity in a single module, making it ideal for high-density deployments where a large number of devices need to be connected to the network.
- High performance: The module has a forwarding capacity of up to 176 Gbps, low latency of 5-10 microseconds, and a maximum throughput of 48 Gbps, which means it can handle a high volume of network traffic without introducing latency or packet loss.
- Flexibility: The module uses Small Form-Factor Pluggable (SFP) transceivers to provide Gigabit Ethernet connectivity, allowing for greater flexibility in network design. Different types of SFP transceivers can be used to support different types of fiber optic or copper connections.
- Compatibility: The N7K-M148GS-11L module is compatible with Cisco Nexus 7000 Series switches, including the Nexus 7010, 7018, and 7710 models, making it easy to integrate into existing data center infrastructure.
- Power efficiency: The module has a maximum power consumption of 450 watts, which makes it energy-efficient and cost-effective to operate.
- High availability: The module is designed for high availability, with features such as hot-swappable components, redundant power supplies, and redundant management modules, ensuring that the network remains operational even in the event of a component failure.
- Simplified management: The module can be managed using Cisco Nexus Operating System (NX-OS), which provides a unified management platform for Cisco Nexus switches, simplifying network administration and reducing management complexity.
The N7K-M148GS-11L Cisco Nexus 7000 Series 48 Ports Gigabit Ethernet I/O Module provides several security features to help protect the network from potential threats. Here are some of the key security features of the module:
- Access control: The module supports access control lists (ACLs), which allow network administrators to control access to the network based on source and destination addresses, protocols, and ports. This helps to prevent unauthorized access and can also be used to block malicious traffic.
- Port security: The module supports port security, which allows network administrators to restrict access to specific ports on the switch. This can be used to prevent unauthorized access to the network and can also be used to limit the number of devices that can be connected to a port.
- Authentication: The module supports various authentication protocols, including 802.1x, which allows network administrators to control access to the network based on user credentials. This can be used to prevent unauthorized access and can also be used to enforce security policies.
- Encryption: The module supports various encryption protocols, including Secure Sockets Layer (SSL) and Transport Layer Security (TLS), which can be used to secure communications between network devices.
- Network segmentation: The module supports virtual LANs (VLANs), which can be used to segment the network into smaller, more secure subnets. This can be used to restrict access to sensitive data and can also be used to prevent the spread of malware and other threats.
- Threat detection: The module supports various threat detection mechanisms, including the Cisco TrustSec solution, which provides end-to-end security by authenticating users and devices and enforcing access policies.
High Availability and Redundancy Options
The N7K-M148GS-11L Cisco Nexus 7000 Series 48 Ports Gigabit Ethernet I/O Module is designed for high availability and redundancy, with several features that ensure the network remains operational even in the event of a component failure. Here are some of the high availability and redundancy options of the module:
- Hot-swappable components: The module has hot-swappable SFP transceivers, which can be replaced without shutting down the module or the switch. This allows for maintenance and upgrades to be performed without disrupting network operations.
- Redundant power supplies: The module has two power supply bays, each with its own power supply. If one power supply fails, the other will take over to ensure that the module continues to function without interruption.
- Redundant management modules: The Cisco Nexus 7000 Series switch, which the module is designed to work with, has redundant management modules. If one management module fails, the other will take over to ensure that the switch and the module continue to function without interruption.
- Virtual PortChannel (vPC): The module supports vPC, which allows two switches to appear as a single logical switch to the network. This provides redundancy and load balancing for network traffic, ensuring that the network remains operational even if one switch or module fails.
- Graceful restart: The module supports graceful restart, which allows for the fast recovery of network protocols after a module or switch reboot. This ensures that network services are restored quickly and reduces the impact of any disruptions.
