Guidelines for operating in SmartFabric mode
The guidelines and restrictions while operating in SmartFabric mode are as follows:
● When operating with multiple chassis, ensure that the switches in A1/A2 or B1/B2 in one chassis are interconnected only
with other A1/A2 or B1/B2 switches respectively. Connecting switches that are placed in slots A1/A2 in one chassis with
switches in slots B1/B2 in another chassis is not supported.
●
Uplinks must be symmetrical. If one switch in a SmartFabric has two uplinks, the other switch must have two uplinks of the
same speed.
● Enable LACP on the uplink ports for switches being uplinked.
● You cannot have a pair of switches in SmartFabric mode uplink to another pair of switches in SmartFabric mode. You can
only uplink a SmartFabric to a pair of switches in Full Switch mode.
SmartFabric network topologies
The SmartFabric Services support three network topologies with specific IOM placement requirements.
● 2 x MX9116n Fabric Switching Engines in different chassis
● 2 x MX5108n Ethernet Switches in the same chassis
● 2 x MX9116n Fabric Switching Engines in the same chassis
2 x MX9116n Fabric Switching Engines in separate chassis
This placement is recommended while creating a SmartFabric on top of a scalable fabric architecture. This configuration
supports placement in Chassis1/A1 and Chassis 2/A2 or Chassis1/B1 and Chassis 2/B2. A SmartFabric cannot include a switch in
Fab A and a switch in Fab B. If one of the chassis fails, placing the FSE modules in separate chassis provides redundancy. Both
the chassis must be in the same MCM group.
2 x MX5108n Ethernet Switches in the same chassis
The MX5108n Ethernet Switch is supported only in single chassis configurations. The switches must be placed in slots A1/A2 or
slots B1/B2. A SmartFabric cannot include a switch in Fab A and a switch in Fab B.
