Nexus 5000 Series Switch Fabric Manager Software Configuration Guide
OL-16598-01
Chapter 1 Product Overview
Typical Deployment Topologies
• MAC ACLs and IP ACLs, including port-based ACLs (PACLs) and VLAN-based ACLs (VACLs).
Virtual Device Contexts
Cisco NX-OS can segment operating system and hardware resources into virtual device contexts (VDC)
that emulate virtual devices. The Nexus 5000 Series switch does not support multiple VDCs. All switch
resources are managed in the default VDC.
Typical Deployment Topologies
In this release, the Nexus 5020 switch is typically deployed in the following topologies:
• Ethernet TOR Switch Topology, page 1-8
• IOC Topology, page 1-10
Ethernet TOR Switch Topology
The Nexus 5020 switch can be deployed as a 10-Gigabit Ethernet top-of-rack (TOR) switch, with uplinks
to the data center LAN distribution layer switches. An example configuration in shown in Figure 1-2.
In this example, the blade server rack incorporates blade switches that support 10-Gigabit Ethernet
uplinks to the Nexus 5020 switch. The blade switches do not support FCoE, so there is no FCoE traffic
and no Fibre Channel ports on the Nexus 5020 switch.
In the example configuration, the Nexus 5020 switch has Ethernet uplinks to two Catalyst switches. If
STP is enabled in the data center LAN, the links to one of the switches will be STP active and the links
to the other switch will be STP blocked.
