As i described in another Post there is the possibility to change a ACI Leaf Uplink Port to Downlink mode. This can be useful if you require some 40/100G Ports but don’t want to add new Leafs.
If you now wan’t to convert some of these Downlinks back to Uplinks, you can follow this guide here.
(more…)Since ACI release 3.1(1) it’s now possible to use some of the Leaf Uplinks as Downlink Ports. This could help you out if there is a need for some 40/100G ports but you are currently only running 10G Leafs.
Currently the following Leafs support the conversion:
There are some limitations, check them out on the Cisco Page.
Our use case was to use some of the 40/100G Ports as Downlinks on a N9K-C93180YC-FX. The main limitation there is that the last 2 ports (53 and 54) don’t support conversion, no issue if you use them as Uplinks anyway.
