You can try either setting the trunk ports on both sides to enable edge port to use fast-link so the ports automatically forward when physical link is established. https://www.cisco.com/c/en/us/support/docs/smb/switches/cisco-small-business-200-series-smart-switches/smb81-setup-spanning-tree-protocol-stp-on-a-interface-on-the-200-3.html Also, check and try different global spanning tree configurations. https://www.cisco.com/c/en/us/support/docs/smb/switches/cisco-small-business-200-series-smart-switches/smb3209-configure-spanning-tree-protocol-stp-status-and-global-setti.html I wish I could give you better advice regarding Spanning Tree but I despise it and I think it's the bane of networking. I never trusted it and it often found it caused more problems. _______________________________________________ PLUG: https://pdxlinux.org PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
