Introduction
This document describes the Cisco NX-OS configuration limits for Cisco Nexus 9000 Series switches.
The values provided in this guide should not be interpreted as theoretical system limits for Cisco Nexus 9000 Series hardware or Cisco NX-OS software. These limits refer to values that have been validated by Cisco. They can increase over time as more testing and validation is done.
Verified Scalability Limits - Unidimensional
The following tables in this section list the verified scalability limits of the Cisco Nexus 9000 Series switches for Cisco NX-OS Release 10.5(1)F.
-
Cisco Nexus 2000 Series Fabric Extenders (FEX) Straight Through Mode Verified Scalability Limits
-
IP Fabric for Media Solution Policer Verified Scalability Limits
-
NetFlow Scalability Support (Flows) for Cisco Nexus 9500 Family Switches
These limits are validated with a unidimensional configuration. The values provided in these tables focus on the scalability of one particular feature at a time.
Each number is the absolute maximum that is currently supported by this Cisco NX-OS release for the corresponding feature. If the hardware is capable of a higher scale, future software releases could increase this verified maximum limit. Results might differ from the values that are listed in this guide when you try to achieve maximum scalability with multiple features enabled.

Note |
For network scalability, Cisco recommends using a hierarchical routing design with multi-hop BGP for advertising the attached prefixes from a top-of-rack (ToR) or border leaf switch. ECMP group creation will be limited if the next-hop adjacency space is exhausted. |

Note |
The scale numbers are based on the TCAM space available on the Cisco Nexus 9300-FX switches. A IPv4 flow monitor uses 4 TCAM space for the Cisco Nexus 9300-FX switches. Similarly, a IPv6 flow monitor uses 2 TCAM space for the Cisco Nexus 9300-FX switches. For port channels, SVIs, and VLANs that have port from both 9300-EX and 9300-FX switches, the lower common denominator limit of the 9300-EX and 9300-FX switches is applied. |

Guidelines and Limitations for OSPF Verified Scalability Limits
-
To achieve the highest scale, we recommend that you use a single OSPF instance instead of multiple instances.
-
Each OSPFv2 and OSPFv3 scale value might vary when combined with other parameters.
-
The graceful restart timeout value might be increased in multidimensional scenarios.

Verified Scalability Limits - Multidimensional
The tables in this section list the verified scalability limits for the Cisco Nexus 9000 Series platform switches. These limits are validated with a multidimensional configuration. The values provided in these tables focus on the scalability of all listed features at the same time.
For each corresponding feature, the number given is the absolute maximum currently supported in this release. If the hardware is capable of a higher scale, future software releases might increase this verified maximum limit. Results might differ from the values listed here when trying to achieve maximum scalability with multiple features enabled.
Note |
These numbers are not the maximum verified values if each feature is viewed in isolation. For these numbers, see the corresponding "Verified Scalability Limits" section. |

Deployment Case Studies
This section provides sample topologies for some common deployments. For each topology, the scalability numbers are the limits with all of the listed features enabled at the same time.
Attention |
These numbers are not the maximum verified values if each feature is viewed in isolation. For these numbers, see the "Verified Scalability Limits" section. |
VXLAN BGP/eVPN iBGP Centric Topology
This VXLAN BGP/eVPN iBGP centric topology consists of Cisco Nexus 9300 and 9500 Platform switches acting as VXLAN vPC tunnel endpoints (VTEPs) and VXLAN non-vPC VTEPs. VXLAN VTEPs establish iBGP sessions to a Cisco Nexus 9508 switch (route reflector) acting as a spine node. VXLAN-distributed anycast gateway SVIs are configured for dual stack, and the traffic is dual stack.
The focus of this topology is to test VXLAN overlay network scale and underlay Layer 2 switching and other routing, multicast, and Layer 4 through Layer 7 features for management and operations. Underlay PIM neighbors and IS-IS adjacency were tested with the default timer and Bidirectional Forwarding Detection (BFD) enabled on all links.
In the following table, the Verified Limit column lists the verified scaling capabilities with all listed features enabled at the same time. These numbers are not the maximum verified values if each feature is viewed in isolation.
