Hi, I have a couple of 3550's routing between VLAN's perfectly. Now I need to add some ACL's to the VLAN interfaces, but read that the SMI cannot apply normal ACL's and I will need to upgrade to EMI for this. Do I have an alternative in order to secure VLANs from one another (just basic stuff like blocking NetBios traffic and only allowing www, tcp ports through etc.) Thanks, Jo
