Greetings again. I am looking to "split" a 2900XL (IOS 12.0(5.3)WC(1))\nso that it will act like three independent (non-VLAN) switches. For\nexample, traffic on ports 1-8 isolated from traffic on ports 9-16, and\nboth isolated from traffic on ports 17-24, as well as each other. The\nhosts on all ports are running non-VLAN/untagged (both ingress and\negress, of course).\n\nIs this possible? Is "switchport multi-vlan" applicable?\n\nI do have a 2620 in the same rack, although it's only got IP-non-plus,\nso I don't think router-on-a-stick/VLAN trunking would work without an\nupgrade. And, unless the 2900 can be made to tag/untag traffic via the\nhost ports/trunk ports, respectively, how would that work?\n\nI've done this on Intel switches, but the cisco nomenclature is\nconfusing. Thanks for your comments.
