1.6.3.7 SPB Interface Configuration
Since we will be adding an IST interface via the red rear ports, ports 38 & 39, we will have to disable
LACP on these ports and add an MLT.
Disable LACP on ports 38 and 39
Same configuration on all switches

SPB Interface Configuration
Rear ports – for this configuration example, we are provisioning only the FI Red (ports 38-39) which are
also used for the IST and Black FI (ports 34-36) rear ports. For the FI black ports (ports 34 to 36), we
simply just need to select one of the rear ports and enable SPB as all ports are using the same LACP
LAG.
Rear Ports: Same configuration on all switches
