The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS configuration limits for the 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.
This table lists the unidimensional verified scalability limits for Cisco NX-OS Releases 6.1(2)I1(1) and 6.1(2)I1(3). 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 currently supported by this Cisco NX-OS release for the corresponding feature. 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.

*The IPv4 and IPv6 routes share the same hardware table.
**The IPv4/IPv6 host routes and IPv4 multicast routes share the same hardware table.
Note | High availability (graceful restart and stateful switchover) is not supported when unicast or multicast aggressive timers are configured at any scale. |
