WAN, Routing and Switching: VLAN AND STRIPPING- HELP
Posted by: cozyk1515 - Senior Network Admin, PrimeLink - Jun 20, 2007, 8:31am PST
Interface GigabitEthernet1/46- 1/48 are fiber points coming in off my Fiber equipment.
INT GIG1/1- 1/4 are going back to my Layer 3 Swtich. The fiber company wants me to give each customer its own VLAN - I know what to do for the Fiber ports (1/46-1/48 is just keep adding Addtional Vlans IE: switchport trunk allowed vlan 84,85), But I don't want to use any more then port 1-4 back to my Layer 3)
As you see I have 1 Vlan Assgined to each port back to my Switch.- How do I change that?

A VLAN is a group of end stations with a common set of requirements, independent of physical location. VLANs have the same attributes as a physical LAN but allow you to group end stations even if they are not located physically on the same LAN segment.
VLANs are usually associated with IP subnetworks. For example, all the end stations in a particular IP subnet belong to the same VLAN. Traffic between VLANs must be routed. LAN port VLAN membership is assigned manually on an port-by-port basis

Hi
Not sure i fully understand. If you only want to use ports gi1/1 - 1/4 and no more but there are more customer vlans than 4 then you could make one of the gigbait connections a trunk and carry aall vlans down it ?
Have i misunderstood ?
