New and Changed Features Send documentation c omment s to nexus5kdocs@cisco.com • 2 Power supplies (AC or DC power supplies). • 1 Fan module with a choice of standard or reversed airflow. Reversed Airflow and DC Power Options The Cisco Nexus 2200 Series Fabric Extenders offer a choice of standard airflow (port-side exhaust) and reversed airflow (port-side intake), as well as a choice for AC and DC power options.
New and Changed Features Send documentation c omment s to nexus5kdocs@cisco.com Fibre Channel over Ethernet N-Port Virtualization Beginning with Cisco NX-OS Release 5.0(3)N2(1), Fibre Channel over Ethernet N-Port Virtualization (FCoE NPV) is supported on the Cisco Nexus 5000 Series switches. The FCoE NPV feature is an enhanced form of FIP snooping that provides a secure method to connect FCoE-capable hosts to an FCoE-capable FCoE forwarder (FCF) switch.
Upgrading or Downgrading to a New Release Send documentation c omment s to nexus5kdocs@cisco.com Auto-Negotiation Disable Beginning with Cisco NX-OS Release 5.0(3)N2(1), you can disable auto-negotiation on a switch port. This feature allows you to connect devices that do not support auto-negotiation (for example, certain DWDM multiplexers) to a Cisco Nexus 5000 Series switch.
Upgrading or Downgrading to a New Release Send documentation c omment s to nexus5kdocs@cisco.com Upgrade and Downgrade Guidelines The following guidelines apply to Cisco NX-OS Release 5.0(3)N2(2) and Release 5.0(3)N2(1) for the Cisco Nexus 5000 Series switches: • Do not change any configuration settings or network settings during the upgrade. Any changes in the network settings may cause a disruptive upgrade. • Cisco NX-OS Release 5.0(3)N2(2) and Release 5.

Limitations Send documentation c omment s to nexus5kdocs@cisco.com Before downgrading to an earlier release, change the LACP rate to normal. If you ignore the warning and force the installation, then it is possible that the leftover LACP rate fast configuration would still be active with previous releases of software but the behavior would be unpredictable and link flap might occur. We recommend that you change the LACP rate setting to normal. For details, see CSCth93787.
Limitations Send documentation c omment s to nexus5kdocs@cisco.com In a vPC configuration, the MTU per class needs to be consistent on both switches in the vPC domain for the vPC peer link to come up. When upgrading/downgrading a working vPC setup between pre-4.2(1)N1(1) and 4.2(1)N1(1) releases, the MTU is adjusted to make sure that the MCT peer-link always comes up.
Limitations Send documentation c omment s to nexus5kdocs@cisco.com 2008 May 14 15:55:43 switch %KERN-3-SYSTEM_MSG: FCP_ERRFCP_PORT: gat_fcp_isr_ip_fcmac_sync_intr@424, jiffies = 0x7add9a:Unknown intr src_id 41 - kernel These messages are informational only, and result in no loss of functionality.
Limitations Send documentation c omment s to nexus5kdocs@cisco.com SPAN Limitations on Fabric Extender Ports The SPAN limitations on Fabric Extender ports are as follows: • On a Cisco Nexus 5000 Series switch, if the SPAN source is a FEX port then the frames will always be tagged when leaving the SPAN destination. • On a Cisco Nexus 5010 switch or a Nexus 5020 switch, if the SPAN source is an access port on a switch port or FEX port, the spanned frames at the SPAN destination will be tagged.
Caveats Send documentation c omment s to nexus5kdocs@cisco.com Checkpoint and Configuration Rollback Limitation When FCoE is enabled, the checkpoint and configuration rollback functionality is disabled. Layer 3 Limitations Asymmetric Configuration In a vPC topology, two Cisco Nexus 5000 switches configured as vPC peer switches need to be configured symmetrically for Layer 3 configurations such as SVIs, Peer Gateway, routing protocol and policies, and RACLs.
