Description
Introduction to the L3 Switch
The N3K-C3048-BA-L3 Cisco Nexus 3048 is a high-performance, high-density, 1RU switch designed for data center environments. It offers 48 1/10-Gbps SFP+ ports, which can support both LAN and SAN networking. The switch is manageable and can support Layer 3 routing protocols, making it suitable for environments with a large number of VLANs. Additionally, it is equipped with advanced features such as virtual PortChannel (vPC) and Cisco FabricPath, which provide increased network flexibility and availability. With its low latency and high throughput, the N3K-C3048-BA-L3 is an ideal choice for data center networks that require high-performance, high-density switching.
Power Options and Redundancy
Power options refer to the different types of power sources that can be used to power the Cisco Nexus 3048 48-Ports Manageable Layer 3 Switch (N3K-C3048-BA-L3). The switch supports both AC and DC power inputs. This means that it can be powered by either an alternating current (AC) power source, such as a standard electrical outlet, or a direct current (DC) power source, such as a battery.
Power redundancy refers to the ability of the switch to continue operating even if one of its power sources fails. The N3K-C3048-BA-L3 has built-in power redundancy, meaning it has two power supplies installed, one primary and one redundant. In case the primary power supply fails, the redundant power supply will automatically take over and supply power to the switch, ensuring continuous operation and minimizing any downtime.
Additionally, the N3K-C3048-BA-L3 also supports redundant, hot-swappable fan modules. This means that the switch has multiple fan modules installed, and if one of them fails, the other one will take over without any disruption to the switch’s operation. This allows for quick replacement of failed fan modules without having to shut down the switch.
Security and management
The Cisco Nexus 3048 48-Ports Manageable Layer 3 Switch (N3K-C3048-BA-L3) provides a variety of security and management features to help protect your network and simplify its management.
Security features include:
- Access control lists (ACLs) to restrict access to specific network resources
- IEEE 802.1X port-based authentication to control access to the switch
- Secure Shell (SSH) and Secure Sockets Layer (SSL) for secure remote management
- IP Source Guard to prevent IP spoofing attacks
- DHCP snooping to prevent DHCP server spoofing attacks
Management features include:
- A command-line interface (CLI) for configuring and managing the switch
- A web-based graphical user interface (GUI) for configuring and monitoring the switch
- SNMP for monitoring the switch and receiving alerts
- Cisco Network Assistant for simplified configuration and management of multiple Cisco switches
- Cisco Prime for centralized management of multiple Cisco devices in a network
Additionally, the N3K-C3048-BA-L3 supports features such as:
- Virtual Device Context (VDC) for segmenting the switch into multiple virtual switches, each with its own resources and configurations
- Flexible NetFlow for monitoring network traffic and identifying trends
- Cisco Discovery Protocol (CDP) for discovering and mapping other Cisco devices on the network
All these security and management features help to provide a secure and easy-to-manage network.
