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.
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. The port 10 operates at 40GbE instead of 100GbE because all VLT links must run at
the same speed.
