FAQs

Q: Does the N3K-C3048TP-1GE support Power over Ethernet (PoE)?
A: No, this model does not support PoE. It provides 48 Gigabit Ethernet ports and 4x 10G SFP+ uplinks for high-speed data center connectivity without power delivery capabilities.

Q: What routing protocols are supported on the Nexus 3048TP-1GE?
A: The switch supports a comprehensive Layer 3 routing suite including BGP, OSPF, EIGRP, RIPv2, PIM-SM, SSM, and MSDP. It also supports 64-way ECMP for scalable Layer 3 fabric designs.

Q: Is this switch suitable for top-of-rack deployment in data centers?
A: Yes, the Nexus 3048TP-1GE is specifically designed as a line-rate Gigabit Ethernet top-of-rack switch. Its 1RU form factor, low latency, and integration with Cisco Nexus fabric make it ideal for data center ToR applications.

Q: What advanced data center features does this switch support?
A: The switch supports Virtual PortChannel (vPC) for Layer 2 multipathing, VXLAN for network virtualization, Cisco Nexus Data Broker for traffic monitoring, advanced buffer monitoring, and Power On Auto Provisioning (POAP) for automated deployment.

Q: What licensing is required for the N3K-C3048TP-1GE?
A: The switch requires the Base license (N3K-C3048-BAS1K9) for core functionality. For advanced Layer 3 and data center features, the LAN Enterprise license (N3K-C3048-LAN1K9) is available and requires the Base license to be installed first.
