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(2)F.

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

  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 up to 500 commands under config-profile.

Note

  • The scale for vPC convergence is tested with an LACP supported device connected to the vPC pair link.

  • For interface port-channel configuration, LACP vPC convergence must be enabled. For more details, see the Configuring vPCs section of the Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide.

  • For vPC domain configuration, the tested time for the delay restore is 150 seconds, the delay restore for interface VLAN is 150 seconds, and the delay restore for orphan ports is 140 seconds. For more details, see the Configuring vPCs section of the Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide.

  • Above NAT scale numbers are supported provided that enough TCAM resources configured and allocated.

25 Nexus 9348GC-FX3PH switch has feature limitations due to Half Duplex only ports, see Cisco Nexus 9000 Series NX-OS System Management Configuration Guide, Release 10.4(x).
26 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.
27 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.
28 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.
29 When configuring a NetFlow flow monitor on a range of VLAN interfaces, the process can be time-consuming (approximately 30 minutes) depending on the range of VLANs specified in the command. To reduce wait time, limit the number of VLANs or specify the VLANs in chunks. Note: On a 9500 modular chassis with 9700-FX or 9700-GX modules, the configuration takes significantly longer time compared to other switches.

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.

35 If you have more than 490 groups, then only one group per SVI. SVIs cannot have a user defined MAC or any VRRP group with it.
36 If you have more than 490 groups, then only one group per SVI. SVIs cannot have a user defined MAC or any VRRP group with it.
37 If the user has Multi-protocol configuration, user should configure appropriate CoPP policies to avoid any control plane traffic drops.
38 When using PBR with the "set vrf" option, if the user attempts to shut down the recircular port, it will trigger a modify PPF session from RPM. If the maximum labels (510) have already been consumed and atomic update is enabled, a "label allocation failure" will occur. To avoid this, the user needs to disable atomic update.
39 128-way ECMP paths are not supported for MPLS, VXLAN, and L3 tunnels. Resilient hashing is not supported on Cisco Nexus 9808 switch for routing, PBR and Port-channel.
40 VM Routes are service routes which are recursively resolved over its Gateway IP/VNF.

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

    • 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.

41 In case of IR, each VNI can have a max of 64 peers.
42 All the other BGW numbers (number of supported L2VNIs, L3VNIs, MAC addresses, IP addresses, and so on) match the values supported on a generic VXLAN EVPN VTEP node.
43 Total number of Cloudsec Security Associations in hardware = 128 (M *N*L) where (M = no. of Cloudsec peers, N = no. of uplinks on each Cloudsec endpoint, L is number of border gateway nodes)
44 This feature is not supported on Nexus 9348GC-FX3, 9348GC-FX3PH, 9332D-H2R and 93108TC-FX3 switches.
45 Multi-Site enabled with TRM supported number of L2VNIs –1000 and L3VNIs –100. Maximum supported multicast underlay and overlay route is 8000. From Cisco NX-OS Release 10.2(3), Multi-Site enabled with TRM supported number of L3VNIs –250. Maximum supported multicast underlay and overlay route is 32000 for Nexus 9700-FX/FX3/GX/GX2 and 8000 for Nexus 9700-EX/FX2 and Nexus 9508.
46 Total number of Cloudsec Security Associations in hardware = 128 (M *N*L) where (M = no. of Cloudsec peers, N = no. of uplinks on each Cloudsec endpoint, L is number of border gateway nodes)
47 Number of vrfs * number of sites = 1000
48 IPv6 unicast traffic is supported only with 9500-FM-G Fabric Modules.
49 VXLAN underlay and overlay multicast routes shares the same hardware table. Maximum Multicast routes is 8000 in the default mode. If you want more overlay route scale, reduce the underlay multicast control group.
50 In case of IR, each VNI can have a maximum number of 64 peers; 512 peers supported on 100 VNIs only.
51 Only one provider VLAN is supported.
52 The maximum number of Layer-2 subinterfaces is based on the available entries allocated for ing-pacl-sb tcam region.
53 Since Nexus 9300-FX have only one slice, the maximum number of Layer-2 subinterfaces that can be created is lower than the limit for Nexus 9300-FX2.
54 The full scale of 3900 L3VNI is only supported on the platforms with >24G memory. Nexus 93240YC-FX2, 93360YC-FX2, 93216TC-FX2, 93108TC-FX3P, 93180YC-FX3 would require add-on memory to support extended 3900 L3VNI scale. Nexus N9K-C9358GY-FXP and N9K-C92348GC-X can not support extended scale.
55 Switches running scaled deployment, including scaled BGP EVPN VXLAN VNI, the memory alert may be seen during Non-Disruptive ISSU as the default system memory threshold has been lowered beginning with Cisco NX-OS Release 10.3(3)F release. To avoid system reacting to critical memory alert, before upgrade configure higher value for system memory thresholds. For example: Set system memory thresholds as 90 for minor, 94 for severe, and 95 for critical.
56 ECMP objects are not shared across multiple VRFs.
57 The full scale of 2000 L3VNI is only supported on the platforms with >24G memory. Nexus 93240YC-FX2, 93360YC-FX2, 93216TC-FX2, 93108TC-FX3P, 93180YC-FX3 would require add-on memory to support extended 2000 L3VNI scale. Nexus N9K-C9358GY-FXP and N9K-C92348GC-X can not support extended scale.
58 Only 26,000 (peer, L3VNI) adjacencies are supported for Nexus 9808/9804 switches with X9836DM-A and X98900CD-A line cards.
59 All /64 routes + 4000 for non /64 routes.
60 All /64 routes + 4000 for non /64 routes.
61 ECMP objects are not shared across multiple VRFs.
62 All /64 routes + 4000 for non /64 routes.
63 All /64 routes + 4000 for non /64 routes.
64 ACL TCAM region for ing-sup should be carved to a minimum of 768 using 'hardware access-list tcam region ing-sup <size>' on Cisco Nexus 9300-FX switches.

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.
