Introduction

The scalability of Cisco Nexus 7000 Series switches has been verified for the following features:

- Cisco Nexus 2000 Series Fabric Extender connectivity to Cisco Nexus 7000 Series switches

- FabricPath

- Fibre Channel over Ethernet (FCoE)

- Interfaces

- Layer 2 switching

- Locator/ID Separation Protocol (LISP)

- Multiprotocol Label Switching (MPLS)

- Multicast routing

- Overlay Transport Virtualization (OTV)

- Quality of Service (QoS)

- Security

- System management

- Unicast routing

- Virtual device context (VDC)

- Private VLAN (PVLAN)

- Remote Integrated Service Engine (RISE)

- Virtual Extensible LAN (VXLAN)

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.

Note

- To achieve the highest VLAN per Fabric Extender (FEX) port scale, Cisco recommends connecting FEX uplinks to one switch on chip (SoC) on F2/F2e or F3 series modules instead of spreading them across different SoCs.

- In Cisco NX-OS 7.3(0)D1(1) release, the number of Fabric Extenders in Active-Active mode is 32.

- In Cisco NX-OS 8.3(1) release, FEX does not support F4 series modules.

Guidelines and Limitations for vPC Configuration Limits

The following vPC values are validated in Cisco NX-OS Release 8.0(1).

Number of vPCs / VLANs - Sup2e 768/4k

Number of physical port vPCs on front panel ports (LAN) - 768

Number of physical port vPCs on FEX (LAN) - 1500

Number of physical port vPC+ on front panel ports - 384

Number of multicast groups - 24k

Note

Refer to Table-6 for individual module scale numbers.

The vPC configuration limits such as the number of vPC+ and VLANs in a vPC+ domain depend on many different parameters. The following templates are validated in the Cisco NX-OS 7.3(0)DX(1)) release with different I/O modules where applicable and should be used as a guide in planning your deployment. The Profile D column in the following table is applicable to Cisco NX-OS Release 6.2(x) only.

*From Cisco NX-OS Release 8.3(1), SUP1 is End of Life (EOL).

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.

Note

For more information about Spanning Tree Protocol , refer to sections Rapid PVST+ Scale Considerations and MST VLAN Scale Considerations in Cisco Nexus 7000 Series NX-OS Layer 2 Switching Configuration Guide.

Note

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.

[1] The default COPP limit for ARP is unchanged. To achieve 3000 ARP PPS with a single module, ARP COPP needs to be changed accordingly. As the COPP is applied at the module, this 3000 PPS can be achieved with multiple modules with the default COPP limits. 3000 ARP PPS is system level supported PPS.

[6] Beginning with Cisco NX-OS Release 8.0(1), on Cisco Nexus 7000 Series Switches M3 Series Line card with HSRP Multiple Group Optimization (MGO) feature, you can scale HSRP groups up to 8000 (dual stacked on 4000 SVIs). With one HSRP-V4 group and one HSRP-V6 group as master and the rest 7998 groups as slave groups. Verified scale is done with two secondary Virtual IPVx addresses on each HSRP group along with the Primary Virtual IPVx address .

- You must create a custom control plane policing (CoPP) policy to change the Committed Information Rate (CIR) to allow more control plane packets.

- Change the u6route-mem command value for VDC from 64 to the default value of 24.

[11] With each new VDC configured, the number of configurable VRFs is reduced by two as each VDC has a default VRF and management VRFs that are not removable. For example, with 4 configured VDCs on Cisco NX-OS Release 6.2, you can configure up to 3992 additional VRFs (either all in one VDC or across VDCs).,

[12] Not all dynamic routing protocols can support having peers in all of the supported VRFs. Refer to the individual protocol scale for more information.

Note

EIGRP scale was dropped to 200 in release 8.0(1) due to a crash issue and fixed in release 8.2(1). Now the EIGRP neighbor scale is raised to 2000 from release 8.2(1) onwards.

Note

For BGP, you must consider FIB Scale as the final parameter. BGP Prefixes will hit the FIB scale limit.

Note

- Number of Layer 3 ARP entries in a M3 module is 128,000.

- Number of Layer 3 ND entries in a M3 module is 128,000.

Note

Layer 3 parameters have the following scale numbers for Cisco NX-OS Release 8.0(1):

- The number of entities attached to one tracking object is 500.

- Total number of FIB entries in hardware is 1 million.

Total number of FIB entries supported in hardware in Cisco NX-OS Release 8.2(1) are:

- Ipv4 routes in a M3 module is 1 million, F3 module is 64K , F2e module is 32K.

- IPv6 routes in a M3 module is 500K , F3 module is 32K , F2e module is 16K.

Note

Total number of FIB entries in a M3 module is 1.7 million IPv4-only routes or 500k IPv6-only routes in Cisco NX-OS Release 8.3(1). When configured together the route scale is 1.1 million ( IPv4 ) + 300K ( IPv6 ) for M3 module in Cisco NX-OS Release 8.3(1).

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 BGP Configuration Limits

- Each BGP scale value might vary when combined with other parameters. See these examples of scenarios tested for Cisco NX-OS Release 6.2 for better guidance.

- All values were tested with default BGP keepalive and hold timers.

- All scenarios were tested with the minimum and maximum configured u4route-mem and u6route-mem under the VDC as 350 MB/110 MB respectively.

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.
