In SmartFabric mode, ports 9 and 10 are automatically configured in a VLT at 40GbE speed. For port 10, use a cable or optic that

supports 40GbE and not 100GbE.

2 x MX9116n Fabric Switching Engines in the same chassis

Use this placement in environments with a single chassis. The switches must be placed in either slots A1/A2 or slots B1/B2. A

SmartFabric cannot include a switch in Fab A and a switch in Fab B.

The fabric design, "2 x Mx9116n Fabric Switching Engines in the same chassis" is supported, but not recommended. Use of this

design displays an error message on the Fabric Topology and View Topology pages of OME - Modular.

Switch to switch cabling

When operating in SmartFabric mode, each switch pair runs a Virtual Link Trunk (VLT) link between them. For the MX9116n, the

port groups 11 and 12 are used.

For the MX5108n, ports 9 and 10 are used. Port 10 operates at 40GbE instead of 100GbE because all VLT links must run at the

same speed. Ensure that you use a cable or optic fibre that supports 40GbE.
