Description

The Cisco Nexus 93128TX is a high-density data center switch designed for top-of-rack and middle-of-row deployments in enterprise, service provider, and cloud environments. With 96 fixed 100M/1/10GBASE-T ports and 8 QSFP+ 40 Gigabit Ethernet uplinks, it delivers 2.56 Tbps of switching capacity and 750 Mpps forwarding rate. Running Cisco NX-OS, this 3RU Layer 3 switch supports advanced features including VXLAN, EVPN, Virtual PortChannel (vPC), and comprehensive security capabilities. Ideal for leaf-spine architectures, virtualized server clusters, and high-performance computing workloads demanding low latency and scalability.

Features

Layer 2 and Layer 3 switching with Enhanced L3 routing (OSPF, BGP, EIGRP, IS-IS, PIM)
- VXLAN with MP-BGP EVPN for network virtualization and overlay services
- Virtual PortChannel (vPC) for active-active redundancy
- Equal-Cost Multipath (ECMP) routing with up to 64 paths
- Comprehensive QoS with priority-based flow control, WRED, and DSCP marking
- Advanced security: ACLs, Cisco TrustSec, MACsec, 802.1X port-based authentication
- Spanning Tree Protocol (STP, RSTP, MSTP, PVST+) support
- Link Aggregation Control Protocol (LACP) for port bundling
- Bidirectional Forwarding Detection (BFD) for fast failure detection
- Uni-Directional Link Detection (UDLD) for link integrity monitoring
- Python scripting and NX-API for programmability and automation
- Hot-swappable redundant power supplies and fan trays
- In-Service Software Upgrade (ISSU) for non-disruptive maintenance
- Cisco PowerOn Auto Provisioning (POAP) for zero-touch deployment
- Flexible airflow: front-to-back or back-to-front cooling options
- Energy-efficient design with variable-speed fans and intelligent power management
- Low latency forwarding for high-performance computing and real-time applications

FAQs

Q: What uplink modules are compatible with the N9K-C93128TX?
A: The N9K-C93128TX supports the N9K-M6PQ or N9K-M6PQ-E (6 active ports), N9K-M12PQ (8 active ports), and N9K-M4PC-CFP2 (2 active 100G ports) uplink modules for 40 Gigabit or 100 Gigabit Ethernet connectivity to aggregation or spine switches.

Q: What licensing is required for this model?
A: The N9K-C93128TX-BA-L3 includes the Enhanced Layer 3 feature set, which provides full Layer 3 routing capabilities including OSPF, BGP, EIGRP, PIM, and VRF-Lite. Network Essentials is required for base Layer 2 features. No separate licensing purchase is needed for the Enhanced L3 features included in this SKU.

Q: Can this switch be used in Cisco ACI fabric deployments?
A: Yes, the Nexus 93128TX can operate in both traditional NX-OS standalone mode and as a leaf switch in Cisco Application Centric Infrastructure (ACI) fabric deployments, providing deployment flexibility for different data center architectures.

Q: Does the switch support stacking or Virtual PortChannel?
A: The Nexus 93128TX does not support traditional stacking but supports Virtual PortChannel (vPC) technology for active-active link aggregation and high availability configurations with redundant switches.

Q: What deployment scenarios is the N9K-C93128TX best suited for?
A: This switch excels in high-density 10GBASE-T server connectivity scenarios such as top-of-rack in virtualized clusters, leaf switches in leaf-spine architectures, and middle-of-row deployments requiring copper 10 Gigabit Ethernet with 40 Gigabit uplinks to aggregation or spine layers.
