You will now create a Port Channel policy group that will be used as an Layer 2 connectivity policy that is part of a single node port channel. In ACI, each policy group for either Port Channel or Virtual Port Channel identifies the bundle of interfaces as a singular interface policy in the fabric. If you think of it from the perspective of traditional NX-OS and IOS, you would create a port-channel interface and assign it a number. Then you would associate the port channel with the interfaces via the channel-group command.

Each policy group is the same. You create a new interface policy group for every group of interfaces that belong the the same channel. These policy groups apply across switch domains. In the case of a Port Channel policy group that would be a single switch. For a Virtual Port Channel it would be across a VPC switch domain.

Step 1 - Navigate to Interface Policy Groups to Create PC Interface Policy Group

To create a PC Policy Group, naviage to Policy Groups by clicking:

1. Fabric
2. Access Policies
3. Expand Interfaces by clicking the toggle arrow (>)
4. Expand Leaf Interfaces by clicking the toggle arrow (>)
5. Expand Policy Groups by clicking the toggle arrow (>)
6. Right-click on PC Interface
7. Click Create PC Interface Policy Group

Step 2 - Create PC Policy Group

In the Create PC Policy Group popup:

1. Name the Policy Group: aci_p21_intpolg_pc
2. For the AEP, select aci_p21_l2_aep
3. For CDP Policy, select aci_lab_cdp
4. For Link Level Policy, select aci_lab_10G
5. For LLDP Policy, select aci_lab_lldp
6. For Port Channel Policy, select aci_lab_lacp
7. For L2 Interface Policy, select aci_lab_l2global
8. Click Next

Step 3 - Create Advanced Policies for the Port-Channel

In the Create PC policy Group - Advanced Policies popup:

1. For MCP Policy select aci_lab_mcp
2. Click Finish

Verify your work and then continue to create the VPC policy group.
