7.0(3)I7(2) |
Fibre Channel Slow Drain Device Detection and Congestion Avoidance |
|
Slow drain device detection and congestion avoidance |
Slow drain device detection and congestion avoidance is supported on the N9K-C93180YC-FX switch |
7.0(3)I7(1) |
Fibre Channel Slow Drain Device Detection and Congestion Avoidance |
|
6 QSFP+ ports as uplink ports or server ports |
The N9K-C93180YC-FX switch supports using 6 QSFP+ ports (40G) used as uplink ports or server ports |
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 |
7.0(3)I7(1) |
|
|
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) |
|
|
FCoE VLANs and virtual interfaces support |
Added support for FCoE VLANs and virtual interfaces. |
7.0(3)I4(1) |
Guidelines and Limitations for FCoE VLANs and Virtual Interfaces |
|
FCoE NPV support |
Initial support |
7.0(3)I3(1) |
