To make the best use of this document, please take note of the following:
-
All numbers are per system unless noted otherwise. For example, a listed number of FCoE fabric logins can be in a single VDC or be a sum of fabric logins across all VDCs in the system. Any changes in the number of supported VDCs do not automatically imply changes in the supported scale for other features.
-
If the latest release has an updated value for a parameter but the previous release does not, specific information for the previous release is not available.
-
If a release is not listed in a specific column in the configuration limits support table, consider the scale numbers listed for the previous release.
-
The values provided in this guide are uni-dimensional. They focus on the scalability of one particular feature at a time. Results might differ from the values listed here when trying to achieve maximum scalability with multiple features enabled.
-
The values provided in this guide should not be interpreted as theoretical system limits for Cisco Nexus 7000 Series and Cisco Nexus 7700 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.
-
Cisco NX-OS Release 6.1 introduced support for Cisco Nexus 7000 Supervisor 2 and Supervisor 2e. Supervisor 2e is designed to provide the highest software scalability. If a higher uni-dimensional scale is verified on Supervisor 2e, the scale values for each supervisor will be listed using the following notation: Supervisor 1 value/Supervisor 2 value/Supervisor 2e value. If Supervisor 2e is not verified to provide a higher uni-dimensional scale for a particular feature parameter, a single scalability value will be listed for all supervisors.
Note
Supervisor 2e is strongly recommended in multi-dimensional scalability scenarios, particularly when multiple VDCs are used and the Cisco NX-OS version deployed is 6.2 or above. From Cisco NX-OS Release 8.3(1) onwards either Supervisor 2e/Supervisor 3 is recommended for the above scenario.
-
Cisco NX-OS Release 6.2 introduced support for Cisco Nexus 7700 switches. Supervisor 2e running on Cisco Nexus 7700 switches provides the same software scalability as Supervisor 2e running on Cisco Nexus 7000 switches.
-
Cisco NX-OS Release 7.2(1)D1(1) introduced support for scale limit monitoring on Cisco Nexus 7000 Supervisor 2 and Supervisor 2E and on Cisco Nexus 7700 switches. The Scale Limit Monitoring feature enables you to monitor the scale limit both at the system level and the VDC level. This feature monitors the scale limits for various features across different VDCs on the device and alerts you if the system crosses the permissible scale limit.

Guidelines and Limitations for BFD Configuration Limits
-
Beginning with Cisco NX-OS Release 6.2, the number of sessions can be all IPv4, all IPv6, or a mix of both.
-
For the highest per-module scale, Cisco recommends using the M2, M3, F2, F2e, or F3 Series modules.
-
For the highest per-system scale, Cisco recommends using Supervisor 2e/Supervisor 3 module.

Note |
The F2, F2e, F3, anx F4 modules synchronize the MAC address tables for a VLAN across all Switch on Chips (SoCs) present in a virtual device context (VDC) when a switch virtual interface (SVI) for the VLAN is configured. Synchronizing the MAC address tables can reduce the number of MAC addresses supported in a VDC to the number of MAC addresses supported in one Switch on Chip, which is16,000 for F2/F2e I/O module and 64,000 for F3/F4 I/O module. |

Inter AS Option B is supported on the M2 modules. Up to 150,000 option B labels are supported from Cisco NX-OS Release 7.2(0)D1(1) onwards. Cisco NX-OS Release 7.3(0)DX(1) and Cisco NX-OS Release 7.3(1)D1(1) support Inter AS Option B on the M3 modules with 150,000 labels. When M2 and M3 modules are used in the same VDC, the supported scale in the VDC is 150,000 labels. Number of VRFs for handoff (MP-BGP) in a M3 module is 4000. |
Guidelines and Limitations for MPLS L2VPN Configuration Limits
-
Each MPLS L2VPN scale value might vary when combined with other parameters.
-
For VPLS, the more sites that are used, the fewer VFIs and bridge domains that can be supported due to the increased number of pseudo-wires to connect sites in a full mesh.
Guidelines and Limitations for MPLS L3VPN Configuration Limits
-
Each MPLS L3VPN scale value might vary when combined with other parameters. See examples of scenarios tested with Supervisor 2e running Cisco NX-OS Release 6.2 for better guidance.
-
The following scenarios were tested in a single VDC as well as in VRFs broken up across four VDCs. 85% of the routes were local, and 15% were remote.

Guidelines and Limitations for IP SLA Configuration Limits
-
To achieve the highest IP SLA probe scale, you might need to add a specific CoPP configuration to allow the IP SLA generated packets to pass through. Otherwise, probes might experience timeouts. See the Cisco Nexus 7000 Series NX-OS IP SLAs Configuration Guide for more details.
-
Even if CoPP is not dropping any IP SLA traffic, round-trip times (RTTs) might vary, so it is important to test locally and set the proper timeout value for IP SLA probes. Generally, Cisco does not recommend setting the IP SLA probe timeout below 1 second.
-
Cisco recommends using Supervisor 2e/Supervisor 3 to achieve the highest scale and the lowest RTT for IP SLA probes.
Guidelines and Limitations for SPAN Configuration Limits
The number of SPAN sessions refers to unidirectional sessions. On the Cisco Nexus 7000 Series switch, two SPAN extended sessions can be combined to create a bidirectional session, and a SPAN standard session can behave either as unidirectional or bidirectional. The Cisco Nexus 7700 switch does not have standard and extended sessions. All SPAN sessions are unidirectional, and any two can be combined to create a bidirectional session. See the Cisco Nexus 7000 Series NX-OS System Management Configuration Guide for more information.

Guidelines and Limitations for All Unicast Routing Configuration Limits
-
High availability (graceful restart, stateful switchover, and ISSU) is not supported when protocol aggressive timers are configured at any scale.
Guidelines and Limitations for OSPF Configuration Limits
-
Cisco recommends using Supervisor 2e/Supervisor 3 module for the highest scale and fastest convergence.
-
To achieve the highest scale, Cisco recommends using a single OSPF instance instead of multiple instances.
-
Each OSPFv2 and OSPFv3 scale value might vary when combined with other parameters. See examples of scenarios tested for Cisco NX-OS Release 6.2 for better guidance. All scenarios were tested with a single OSPF instance.
-
The graceful restart timeout value might need to be increased in multi-dimensional scenarios.
-
The passive interface default was used.

Guidelines and Limitations for HSRP, VRRP, and GLBP Configuration Limits
-
The number of HSRPv2 and VRRPv3 groups can be IPv4 only, IPv6 only, or a combination of both. For example, if Cisco NX-OS supports 4000 HSRP groups, it can also support 4000 VLANs with each running HSRP IPv4 groups or 2000 dual-stacked VLANs.
-
The same FHRP group ID or different group IDs can be used in different VLANs and within the same VLAN for IPv4 and IPv6 groups.
