Understanding ACI packet encapsulation and ACI packet format are important topics for network professionals who aim to gain a deep knowledge of Cisco ACI.
In this video article, I explore ACI iVXLAN encapsulation and explain the ACI packet fields and format.
Summary
- Cisco ACI is an overlay technology that uses a custom VXLAN called iVXLAN for packet encapsulation.
- ACI iVXLAN uses a custom UDP destination port, 48879, instead of the standard VXLAN UDP port 4789.
- When forwarding in the ACI fabric, all traffic is normalized as iVXLAN packets.
- The additional ACI iVXLAN encapsulation is 50 bytes.
The Cisco Application Centric Infrastructure (ACI) Design Guide provides more knowledge about Cisco ACI.
