I've worked with VLAN's before such as assigning ports on a Cisco Catalyst to the necessary VLAN and making sure the cable runs were right, but never set one up from scratch...can you help me fully understand the process? Here's how I've worked it out so far, with the exception of commands I need for the switch.
1. Configure VLAN ID 27 = IP Address will be 10.1.27.x - Assign it to Physical Port 23 (Maybe to a specific computer NIC?)
2. Configure a new DHCP scope to assign 10.1.27.x with the standard default gateway and everything to VLAN ID 27.
3. Configure the VLAN on the switch to ip helper-address
Seems simple enough, but I have a few additional questions:
1. Can you set it to allow 10.1.27.x to talk to 10.1.26.x but not vice versa?
2. Is there something obvious I am missing?
