Introduction

The Cisco Nexus 3064PQ switch is a high-performance, high-density, ultra-low-latency Ethernet switch that is part of the new Cisco Nexus 3000 Series switches. This compact one-rack-unit (1 RU) form factor 1- and 10-Gigabit Ethernet switch provides line-rate Layer 2 and 3 switching. The switch runs the industry-leading Cisco NX-OS software operating system. The Cisco Nexus 3065PQ is well suited for financial co-location deployments that require support for robust unicast and multicast routing protocol features at ultra-low latencies.

Layer 2 and Layer 3 Topology Configuration Limits

This section describes the configuration limits in topologies that include Layer 2 and Layer 3 feature configurations. Table 1-1 shows the Layer 2 and Layer 3 configuration limits for Cisco NX-OS Release 5.0(3)U1(1a):

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)U1(1a) software for the corresponding feature. If the hardware is capable of a higher scale, future software releases may increase this maximum limit.

3 507 VLANs in PVRST mode, 512 VLANs in RPVST mode where 507 are user defined VLANs, and 4,000 VLANs in MST mode.

4 4 active SPAN sessions with the SPAN source in a single direction (RX only or TX only in each span session. 2 active SPAN sessions with the SPAN source in both RX and TX directions.

5 A combination of HSRP and VRRP groups, where the total is 255.



Note If your scale requirements exceed either the Verified Topology or the Maximum Limits, please contact your Cisco representative. Based on your requirements, it may be possible to validate support for your requirement, as long as the scale capability of the hardware is not exceeded.
