Cisco Nexus 5000 Series Configuration Limits
for Cisco NX-OS Release 5.0(3)N2(1)

Release Date: June 13, 2011

Part Number: OL-25324-01

Current Release: Cisco NX-OS Release 5.0(3)N2(1)

This document describes the Cisco Cisco Nexus 5000 Series switch configuration limits for Cisco NX-OS Release 5.0(3)N2(1). Use this document in combination with documents listed in the “Related Documentation” section.

Introduction

The Cisco Nexus 5000 Series switches include a family of line-rate, low-latency, lossless 10-Gigabit Ethernet, Cisco Data Center Ethernet, Fibre Channel over Ethernet (FCoE), and now native Fibre Channel switches for data center applications. The Cisco Nexus 5000 Series includes the Cisco Nexus 5500 Platform and the Cisco Nexus 5000 Platform.

Cisco NX-OS Software Release 5.0(3)N2(1) introduces two new Cisco Nexus 5500 Platform switches that extend the versatility of the data-center class Cisco Nexus 5000 Series switches and provide higher density, lower latency, multilayer services.

The Cisco Nexus 5000 Platform includes the following switches:

  • Cisco Nexus 5020 switch
  • Cisco Nexus 5010 switch

For information about the Cisco Nexus 5000 Series, see the Cisco Nexus 5000 Series and Cisco Nexus 5500 Platform Hardware Installation Guide.

Cisco Nexus 5000 Series and Cisco Nexus 5500 Platform switches have been tested for scaling purposes under the following deployment scenarios:

  • Layer 2-only deployments
  • Layer 2 and Layer 3 combined deployments
  • Fibre Channel and FCOE deployments

Note Verification topologies included all listed features configured to the Verified Limits simultaneously. The Maximum Limit for a given feature is the configuration limit or the hardware limit on a specific platform.

Layer 2 Topology Configuration Limits

This section describes the configuration limits in topologies that include only Layer 2 feature configurations.

Table 1 shows the Layer 2 configuration limits for Cisco NX-OS Release 5.0(3)N2(1):

1.Verified Topology—Indicates the verified scaling capabilities with all listed features enabled at the same time. The numbers listed here exceed that used by most customers in their topologies. The scale numbers listed here are not the maximum verified values if each feature is viewed in isolation.

2.Maximum Limits—Indicates the maximum scale capability tested for the corresponding feature individually. This number is the absolute maximum currently supported by Cisco NX-OS Release 5.0(3)N2(1) software for the corresponding feature. If the hardware is capable of a higher scale, future software releases may increase this maximum limit.

3.Logical interfaces are a product of the number of VLANs times the number of ports. This parameter reflects the load of handling port programming, and is not dependent on the spanning-tree mode or configuration.

4.2,200 entries are reserved multicast MAC addresses. The usable limit for unicast MAC addresses is 13,800.

5.4,000 entries are reserved multicast MAC addresses; 25,000 entries are reserved unicast entries.
