The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

7.0(3)I7(1) |
|
FCoE NPV |
Added support for the N9K-C93180YC-FX switch |
7.0(3)I7(1) |
|
QoS |
Added support of default FCoE policies for network-qos, queuing output, and queuing input |

|
FCoE NPV |
Added support for the N9K-C93180LC-EX switch |
7.0(3)I6(1) |
|
Dual-homed FEX topology (Active/Active FEX topology) |
Introduced this feature. |
7.0(3)I5(2) |
|
Fibre Channel Slow Drain Device Detection |
Added Fiber Channel slow drain device detection support in the N9K-X9732C-EX line card. |
7.0(3)I5(2) |
Fibre Channel Slow Drain Device Detection and Congestion Avoidance |
FCoE NPV |
Added support for the N9K-X9732C-EX line card. |
7.0(3)I5(2) |
|
shutdown lan command support for FEX HIF ports and port-channels |
To avoid having the FCoE link go down when the system detects a vPC inconsistency, use the shutdown lan command to shutdown the LAN traffic on port-channels and individual Ethernet ports. |
7.0(3)I5(1) |
|
Fibre Channel Slow Drain Device Detection |
Enables slow drain device detection and congestion avoidance when slow devices are attached to the network fabric resulting with end devices not accepting frames at a configured rate that leads to traffic congestion on the links |
7.0(3)I5(1) |
Fibre Channel Slow Drain Device Detection and Congestion Avoidance |
FCoE Over FEX support |
Enables Fibre Channel traffic to be carried on a FEX port. The FEX is connected to Cisco Nexus 9000 device (in FCoE NPV mode) through a Fabric Port Channel (FPC). |
7.0(3)I5(1) |
|
MAC bound vFC support |
Binds the virtual Fibre Channel interface to a host MAC address before a virtual Fibre Channel interface can be used. |
7.0(3)I5(1) |
|
Pause frame timeout support |
Enables a pause frame timeout value on a port to empty the buffer space in the ISL link and helps to reduce the fabric slowdown and the congestion on other unrelated flows using the same link. |
7.0(3)I5(1) |
|
shutdown lan command support |
Added support for the shutdown lan command. |
7.0(3)I4(1) |
