Beginning with OME-M 1.20.00 and SmartFabric OS10.5.0.7, additional Scalable Fabric topologies are supported in Full Switch and SmartFabric modes. These topologies are more complex than the ones presented in previous sections. These designs enable physical NIC redundancy using a pair of switches instead of two pairs, providing a significant cost reduction.
These complex topologies support connections between MX9116n FSEs in FabA with MX7116n FEMs in FabB across single and multiple chassis, up to a total of five chassis. Once you connect the FSE and FEMs, ensure that the slot numbers are the same for the connection. For example, MX9116n FSE in slot A1 can be connected to an MX7116n FEM in slot B1 (same chassis), or slot A1 (second chassis), or slot B1 (second chassis), and so on.
The complex scalable fabric topologies in this section apply to dual-port Ethernet NICs.
Single chassis:
- MX9116n FSE in slot A1 is connected to MX7116n FEM in slot B1.
- MX9116n FSE in slot A2 is connected to MX7116n FEM in slot B2.
Dual chassis:
- MX9116n FSE in Chassis 1 slot A1 is connected to MX7116n FEMs in Chassis 1 slot B1, Chassis 2 slot A1, Chassis 2 slot B1.
- MX9116n FSE in Chassis 2 slot A2 is connected to MX7116n FEMs in Chassis 1 slot A2, Chassis 1 slot B2, Chassis 2 slot B2.
Multiple chassis:
The topology with multiple chassis is similar to the dual chassis. Make sure to connect the FSE and FEM in the same numeric slot numbers. For example, connecting FSE in Chassis 1 slot A1 to FEM in Chassis 2 slot B2 is not supported.
