F5 Viprions have different blade hardware versions. There isn’t a simple command that will help you identify the blade model. I have found this to be useful:
(/Common)(tmos)# show /sys hardware field-fmt | grep -e platform -e marketing
sys hardware platform {
marketing-name BIG-IP VPR-C2400
platform A112
Platform A112 is B2250 blade
Platform A113 is B2150 blade
Platform A109 is B2100 blade
