Hello very helpful people!!!
Have a stock Cisco 3500XL, haven't worked on Ciscos in forever, does anyone have a sample config for what I need to accomplish? Few notes, the uplink is port FastEthernet 0/24. I need all ports on the switch to be on VLAN 20 and the uplink to be assigned ip 10.10.25.10 with being on VLAN 10 but being "tagged" also on VLAN 20 so data flows.
