Adding new VLAN to existing VPC

Level 1
Level 1

There already exist a VPC profile and it is up and running. Now there is a requirement to add a new VLAN to this VPC interface.


Can someone detail the steps to do it

Hi LakshmiPrabu,

Welcome to the forum.

I think I understand your question, but the question is "Do you understand how the ACI elements are conneced to creat a VPC?"

And the answer to that question is slightly differentdepending on whether you are using the VPC to:

  1. Connect Bare Metal Hosts (untagged)
  2. Hypervisor Hosts (tagged traffic)
    1. Using a fully automated integrated approach
    2. Mapping VLANs to Application EPGs, which is essentially the same as 3a below
  3. An External switch (trunk port - two methods)
    1. Mapping VLANs to Application EPGs
    2. Mapping individual VLANs to External Bridged Networks (L2 Outs/L2EPGs)
  4. External Router (must be a trunk port)

For the purpose of answering the question, I'm going to assume you are Mapping VLANs to EPGs, as in 2b or 3a above.

You said:

There already exist a VPC profile

By that I assume you have already built this (replace the word My with your naming) assuming the VPC is connected via interface pp on Leaf Switches 101 and 102 and you have used the naming standards for VPCs that I recommend here):




But now you want to add vlan dddd and statically map it to say My-EPG

This is what you do while logged in as admin in Advanced mode (>+ means Right-click):

Step 1:

Fabric>Access Policies>Pools>VLAN Pools>My-VLAN.Pool >+ Create Ranges

Enter the range: VLAN dddd - VLAN dddd


Now navigate to your tenant and map the new vlan to the EPG you wish to add, substituting your values where I have used names beginning with My:

Step 2:

Tenants>MyTenant>Application Profiles>My-AppProfile>Application EPGs>My EPG>Domains (VMs and Bare Metals)>+Add Pyhsical Domain Association

Physical Domain Profile: My-PhysDom


Step 3:

Tenants>MyTenant>Application Profiles>My-AppProfile>Application EPGs>My EPG>Static Paths>+Deploy Static EPG on PC, VPC, or interface

Path Type: Virtial Port Channel

Path: L101..102:pp-VPCIPG

Port Encap (or....): VLAN dddd


Step 4: Test your new VPC mapping which now looks like this:AccessPolicyChain-VPCs-Tenant.jpg



I hope this helps
