Modify one Leaf interface MTU

[sidychaouy1]

Hi,

I would like to modify the MTU on only one interface of a Leaf.

I noticed that we can modify the MTU in Fabric Policies=>Global policies=>Fabric L2 MTU Policy.

But there is for all interfaces of leaves.

Please help me to find how proceed.

Thanks

Hi sidychaouy1,

Unfortunately, there's currently no way to change the MTU of a specific interface on ACI within the access policies. The only option is to change the global MTU policy which will affect the entire fabric, as you've found.

Also, it's worth pointing out that you can configure the MTU of certain interfaces used within External Routed Networks. For example, when configuring OSPF using a Routed Sub-Interface you can specify the MTU setting for the link.

Hope this helps.

Hello

We need perform the same configuration as the subject.

As requeriment of the device connected to the leaf, we need configured only the interface at different MTU as the global.

Also we will need vPC configured with different MTU.

With the new version Version : 2.1(3j) there are some possibility to perform that config?
