What it does
This is a reference translator between VOSS (Extreme's Fabric Connect / SPBM) and EXOS. It lays common tasks side by side so you can see how each command line expresses them, and it is explicit where EXOS has no equivalent - because EXOS does not run SPBM at all. It is a reference, not a config generator: every command is grounded in Extreme documentation, but you should adapt names, ports, and numbers to your own network and verify before applying anything.
The key difference
EXOS and VOSS are different operating systems that run on Extreme's universal hardware. VOSS is fabric-native: it builds an SPBM fabric with IS-IS, nicknames, B-VLANs, and I-SIDs. EXOS does not support SPBM. It joins a Fabric Connect network as a Fabric Attach edge (an FA Proxy or Client), and the VOSS FA Server provisions the I-SID for it. So for the fabric-core tasks - the SPBM instance, the nickname, the B-VLANs, an L3 VSN - there simply is no EXOS command, and the tool says so plainly.
How to use it
Type a task or a fragment of a command (for example i-sid, nickname, vlan, or fabric attach) and the table filters to the matching rows. Each row shows the concept, the VOSS command(s), the EXOS command(s) or a note that there is no equivalent, and a short explanation. Clear the box to see the whole table.
What it is not
It does not generate a deployable configuration, and it does not translate an arbitrary config file line by line. Fabric configuration is high-impact and platform-specific; this tool is meant to help you learn and cross-reference the two CLIs, not to produce config you would paste into a live switch unchecked.
