Power On Auto-Provisioning
Power On Auto Provisioning (POAP) automates the process of upgrading software images and installing
configuration files on Nexus switches that are being deployed in the network for the first time. For more
information, see the Cisco Nexus 5000 Series NX-OS Fundamentals Configuration Guide.
VLAN QoS
On Cisco Nexus 5500 Series devices, you can configure quality of service (QoS) policies for
classification and marking on VLANs. The policies that you apply to a VLAN are applied to the traffic
on the VLAN's Layer 2 and switch virtual interface (SVI) ports. For more information, see the Cisco
Nexus 5000 NX-OS Quality of Service Configuration Guide.
PVLAN On FEX Trunk Ports
You can enable or disable a private VLAN (PVLAN) on FEX trunk ports. FEX trunk ports extend the
PVLAN domain to all the hosts connected to it and when configured, globally affects all FEX ports
connected to the Cisco NX-OS 5000 Series switch.
You must disable all the FEX isolated trunk ports before configuring PVLANs on the FEX trunk ports.
If the FEX isolated trunk ports and the FEX trunk ports are both enabled, unwanted network traffic might
occur.
For more information, see the Cisco Nexus 5000 Series NX-OS Layer 2 Switching Configuration Guide.

The buffer-to-buffer credit range has increased to 240. For more information, see the Cisco Nexus 5000
Series NX-OS SAN Switching Guide.
