FAQs

Q: What is the difference between the N9K-C9372TX and N9K-C9372TX-E?
A: The N9K-C9372TX-E is a minor hardware revision of the N9K-C9372TX with enhanced hardware capability for IP-based Endpoint Group (EPG) classification when operating in Cisco ACI mode. In NX-OS mode, both models offer feature parity and transparent operation.

Q: Does the N9K-C9372TX-E support both NX-OS and ACI operating modes?
A: Yes, the switch can operate in either Cisco NX-OS mode for traditional data center deployments or in Cisco Application Centric Infrastructure (ACI) mode for policy-based automation. The operating mode is determined by the software image loaded on the switch.

Q: What uplink connectivity options are available on this switch?
A: The switch provides 6 fixed 40G QSFP+ uplink ports. These ports support QSFP+ optics including 40GBASE-SR4, 40GBASE-LR4, and breakout cables for 4x10G connectivity using existing 10 Gigabit Ethernet fiber infrastructure.

Q: Can this switch be used in spine-leaf data center architectures?
A: Yes, the N9K-C9372TX-E is designed specifically as a leaf node switch for spine-leaf architectures. It can also be deployed in traditional 3-tier architectures as a top-of-rack or middle-of-row access switch with high-speed 40G uplinks to aggregation or core layers.

Q: Does the N9K-C9372TX-E support Cisco Nexus 2000 Fabric Extenders?
A: Yes, when operating in NX-OS mode, the switch supports up to 16 Cisco Nexus 2000 Series Fabric Extenders, allowing you to extend the switch fabric to remote locations while maintaining centralized management and configuration.
