My telco assigned me an etxented vlan for a metro ethernet deployment. I have no option but to use extended vlans. My routers and remote site hardware have been upgraded and can process extended vlans. My problem is with my sup1a in my central site. My software on the sup1a is 6.4(21). If anyone can offer any suggestions on configuring extended vlans on the sup1a it would be greatly appreciated. Thanks in advance.
