Command History

Release
Modification
4.0(1a)N2(1)
This command was introduced.
4.2(1)N1(1)
The number of uplinks is extended to 8.


Note In releases prior to Cisco NX-OS Release 4.2(1)N1(1), the maximum number of uplinks was 4.


Usage Guidelines

Use the pinning max-links command when you create a number of pinned fabric interface connections to enable the parent switch to determine a distribution of host interfaces. The host interfaces are divided by the number of uplinks and distributed accordingly.


Caution Changing the value of uplinks is disruptive. All the host interfaces on the Fabric Extender are brought down and back up as the parent switch reassigns its static pinning.


Examples

This example shows how to specify the number of statically pinned uplinks for a Fabric Extender:

switch# configure terminal
switch(config)# fex 101
switch(config-fex)# pinning max-links 4
 

This example shows how to revert to the uplink count to the default for a Fabric Extender:

switch# configure terminal
switch(config)# fex 101
switch(config-fex)# no pinning max-links
