CISCO Nexus 3000 Series NX-OS Verified Scalability
Introduction
The values provided in this guide should not be interpreted as theoretical system limits for Cisco Nexus 3000 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 are done.
Verified Scalability Limits
The tables in this section list the Cisco verified scalability limits for Cisco NX-OS Release 9.3(13). 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.
- Verified limits are provided only for supported platforms.
- If a feature is not supported for a particular platform, the verified limit is not provided.
- If the verified maximum values are exceeded in an ALPM or a non-ALPM mode, you get a table full syslog even in the hash collision scenario.
- For the Verified Maximum, 16 path ECMP is tested with 40K IPv4 and 40K IPv6.
- If your scale requirements exceed either the Verified Topology or the Verified Maximum limit, please contact your Cisco representative.
- Based on your requirements, it may be possible to validate support for your requirement, as long as the scale capability of the hardware is not exceeded.

Verified Topology Limits
The tables in this section list the verified scaling capabilities with all listed features enabled at the same time. The scale numbers listed here exceed those used by most customers in their topologies. These numbers are not the maximum verified values if each feature is viewed in isolation.
- The scale numbers in the Verified Topology Limits tables are for the Non-ALPM mode and the default IPv6 LPM carve value is 256 for all the platforms.
- For the verified topology scale numbers for the 3132Q platform, refer to the scale numbers for the 3132Q-X platform since they are identical for both of these platforms.
- All the scale numbers are with Unicast RPF disabled.
