Spanning tree groups

For the purposes of Spanning Tree Protocol negotiation, the ports on a Passport 8000 Series switch can be divided into groups of ports where each group of ports performs its own spanning tree negotiation with neighboring devices. In a Passport 8000 Series switch, these groups of ports are called spanning tree groups (STGs).

The Passport 8100 Switch supports one STG.

The Passport 8600 Switch supports 25 STGs.
