Added support for this feature. |
6.2(6) |
Physical Port VPCs |
Added support for physical port vPCs on the physical interface of vPC peer devices. |
6.2(6) |
BFD for IPv6 Static |
Added support for configuring BFD for IPv6 static routes on an interface. |
6.2(2a) |
FEX |
Cisco Fabric Extenders support Layer 3 protocol adjacencies on host interfaces (HIFs) and DSCP to queue mapping. Before Cisco NX-OS Release 6.2(2), you can configure a Fabric Extender (FEX) port as a Layer 3 interface for host connectivity, but not for routing. |
6.2(2) |
Error Disabled |
Added the ability to view error disabled recovery and detection runtime information. |
6.2(2) |
Show Interface Status Error Policy |
Allows you to view information about interfaces and VLANS that receive an error during policy programming. |
6.2(2) |
Clear SNMP Counters From an Interface |
Added the ability to clear SNMP counters from the interface. |
6.2(2) |
SVI Autostate Disable |

6.2(2) |
BFD on IPv6 |
Added support for BFD on IPv6. |
6.2(2) |
BFD on OSPFv3 |

BFD on IS-ISv6 |
Added support for BFD on IS-ISv6. |
6.2(2) |
Asymmetric |
Allows you to change the hash mechanism in F2 or F2e modules to asymmetric (symmetric by default), which prevents traffic-drop occurring during bi-directional forwarding and improves load balancing. |
6.2(2) |
