<div dir="ltr">Hi James,<div><br></div><div>Have you looked into enabling extended VLAN range: <a href="http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_52_se/configuration/guide/swvlan.html#wp1200242">http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_52_se/configuration/guide/swvlan.html#wp1200242</a></div>
<div>Also, you only need as many spanning tree instances as there are physical topologies, therefore consider migrating to MST: <a href="http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a00807b075f.shtml">http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a00807b075f.shtml</a></div>

We've long since passed the <span style="font-size:12pt">128 per-VLAN spanning tree
