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 tables in this section list the verified scalability limits for the Cisco Nexus 9000 Series switches for Cisco NX-OS Release 10.2(7)M.

These limits are validated with a unidimensional configuration. The values are 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

  1. If only one number is provided, the verified limit applies to all supported platforms and line cards.

  2. Verified limits are provided only for supported platforms.

  3. If a feature is not supported for a particular platform, the verified limit is not provided.


Note

You can deploy upto 500 commands under config-profile.

If each ACL has unique entries, the ACL labels are not shared, and the label limit is 62. In order to achieve 150 services per switch with the limitation of 62 ACLs per slice, the ingress interfaces should be spread across multiple slices of ASIC.

11 Layer 2 unidimensional scale only. SVI, Layer 3 interface, and VXLAN VLANs are not supported. 200K MAC is enabled only when " system routing template-l2-heavy" is configured and the system is reloaded.
12 On EOR, support is for 12,000 PV count with 3967 vlans and RPVST with default timers. If 22,000 PV count is needed with 3968 vlans and RPVST, recommended hello timer value is 4 or higher. It is also recommended to tune forward delay and max age accordingly.

Note

  • The number of supported VLANs per vPC should be within the MST or RPVST virtual port count that is specified in this table, depending on the topology.

  • The number of supported STP VLAN port instances, for Fabric Extender host interface ports, should be less than 13000.

  • The ports with switch port isolated are only supported on Layer 2 ports. However, on Layer 2 the following port types are not supported:

    • FEX host interfaces

    • FEX host interface port channels

    • PVLAN ports

Maximum number of SVIs supported:

  • 492 with IPv4 flow monitors only

  • 246 with IPv6 flow monitors only

  • 165 with both IPv4 flow monitor and IPv6 flow monitors attached

Number of Layer 3 interfaces (Layer 3 ports, port channels, and SVIs) to which IPv4 flow monitors can be applied. You can use the show interface hardware-mappings command to check if the interface belongs to ASIC slice 0 or slice 1.

Maximum number of flows in the software table (IPv4 or IPv6 or CE flows)

Nexus 9000 switches

100,000 flows using the show flow cache command on 9500 modular chassis per line card

1,000,000 flows (1 Million) using the show flow cache command on 9300 switches

Layer 3 interfaces (Layer 3 ports, port channels, and SVIs) to which IPv6 flow monitors can be applied

Nexus 9300-EX switches

252 (with members on just one ASIC slice) or 126 (with members on both ASIC slices). You can use the show interface hardware-mappings command to check if the interface belongs to ASIC slice 0 or slice 1.

Maximum number of concurrent flows supported (IPv4 or IPv6 or CE flows)

Nexus 9300-EX/FX/FX2 switches

6000 traffic flows.

By increasing LCPU-PG-SIZE using the following command one can achieve Max 18000 concurrent flows, after modifying LCPU-PG-SIZE, the switch needs reboot after saving configuration 

switch(config)# hardware qos lcpu-pg-size ?
  <200-10000>  Pool Group size
 
switch(config)# hard qos lcpu-pg-size  5000
Warning:Reload required for configured PG size to take effect. Save configuration and reload the system.
switch(config)# copy running-config startup-config

In Cisco Nexus Release 9.3(3), the hardware qos command is not supported.

14 A single forwarding engine instance supports four SPAN or ERSPAN sessions. For Cisco Nexus 9300 Series switches, if the first three sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. This limitation might also apply to Cisco Nexus 9500 Series switches, depending on the SPAN or ERSPAN source's forwarding engine instance mappings.
15 If the source interface configured for a monitor session is on the same line card, the maximum supported active SPAN sessions are 4. Based on the number of line cards in the EoR, the total number of active SPAN sessions are 4 x n, where n is the number of line cards on EoR, provided the source and destination interface are on the same line module.
16 The number of SPAN or ERSPAN sessions per line card reduces to two if the same interface is configured as the bidirectional source in more than one session.

Note

The scale numbers are based on the TCAM space available on the Cisco Nexus 9300-EX and Nexus 9300-FX switches. A IPv4 flow monitor uses 2 and 4 TCAM space for the Cisco Nexus 9300-EX and Nexus 9300-FX switches respectively. Similarly, a IPv6 flow monitor uses 8 and 2 TCAM space for the Cisco Nexus 9300-EX and Cisco Nexus 9300-FX switches respectively.

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.

24 If the user has Multi-protocol configuration, user should configure appropriate CoPP policies to avoid any control plane traffic drops.

Note
With IPv6 scale, traffic loss could be there for a few seconds during switchover.

The maximum number of PBR next-hops based on 4 FM-E supported is 192 per slice of the forwarding engine


Note

  • The IPv4/IPv6 host routes and the IPv4 multicast routes share the same hardware table. Limits are provided for both the default line card mode and the max host line card mode.

  • The IPv4 and IPv6 unicast routes share the same hardware table. Limits are provided for both the default line card mode and the max host line card mode.

  • High availability (graceful restart and stateful switchover) is not supported when unicast or multicast aggressive timers are configured at any scale.

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 pertaining to each feature.

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.
