FAQs

Q: What is the difference between the N3K-C3172TQ-ZV and other 3172TQ models?
A: The N3K-C3172TQ-ZV is the base Nexus 3172TQ model with 4GB of memory and support for 48 10GBASE-T ports. The -XL variant includes 8GB memory for object-model programming, while the -32T variant ships with only 32 ports enabled by default, requiring a license upgrade for the remaining 16 ports.

Q: Can this switch operate in both Nexus 3000 and Nexus 9000 modes?
A: Yes, the Nexus 3172TQ can operate in either N3K mode or N9K mode. In N9K mode, the switch follows the Nexus 9000 licensing model, where the N3K-LAN1K9 license is required for Layer 3 features instead of the N3K-BAS1K9 license used in N3K mode.

Q: What Layer 3 routing protocols are supported?
A: The switch supports comprehensive Layer 3 unicast and multicast routing including BGP, OSPF, EIGRP, RIPv2, PIM-SM, SSM, and MSDP. Full Layer 3 features require appropriate licensing depending on the operating mode.

Q: Is this switch suitable for top-of-rack deployment?
A: Yes, the Nexus 3172TQ is specifically designed as a cost-effective, power-efficient line-rate Layer 2 and 3 top-of-rack switch for data center environments. It delivers wire-rate performance on all ports and supports virtual port-channel technology for Layer 2 multipathing.

Q: What is the end-of-life status for this model?
A: Cisco announced end-of-sale and end-of-life for the N3K-C3172TQ series in October 2021. While the switch is no longer sold new by Cisco, it remains a viable solution for existing deployments and is widely available through the secondary market with extended third-party support options.
