In order for this to occur, you need to enable the Proxy MAC Learning mode. In this case, the larger MAC address table of the M Series module can be used to learn up to 128,000 total MAC addresses in the FabricPath domain. In Release 6.2(2) and later, any time the F2e is in the same VDC as an M Series module, the F2e operates in Layer 2 mode only. In this Remote MAC learning mode, you are limited to 16,000 total network MAC addresses in the FabricPath domain due to the F Series MAC table capacity. When there is an M Series module and an F1 or F2e in the same VDC, MAC address learning occurs on the core ports of the F Series module by default. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. M1/M2 + F1 Virtual Device Context (VDC) or M1/M2 + F2E VDC at the spine (L2/元 boundary).
Nexus 7000 Release 6.2(2) or later on spine and leaf switches.
The information in this document is based on these software and hardware versions: FabricPath is not supported on the M Series modules, but it can still leverage the MAC table of an M Series module.Ĭisco recommends that you have knowledge of FabricPath basic concepts. This feature allows you to take advantage of the larger MAC table in M Series modules, even in FabricPath. This document describes the Proxy L2 Learning or Proxy MAC Learning feature added in Release 6.2(2) which allows you to increase the MAC scalability in a FabricPath domain.
