• VLANs for SmartFabrics and FCoE 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. 74 SmartFabric Services
