The CLI is similar, the graphical on the foundry is pretty nice. It's been a while since I've messed with them but foundry normally does a single instance of spanning-tree for all vlans as opposed to cisco default PVST. Also check other spanning-tree defaults like if it's doing rapid by default.
Other than that the technology and operation are very similar unless you're doing advanced QoS or routing. IIRC foundry has a really nice application ASIC that tracks flows/conversations.
