I have a Cisco 6500 series with four modules, who's only job in the world is to
have 3 Vlans, 2 lacp-channel ports and a trunk port. ans will never connect to any other switches and routers
Setup required:
Module 3: is a 16 port gigabit switch.
ports 3/1-4 = lacp-channel enabled set to on
ports 3/1 = Trunk port
ports 3/5-8 = vlan10
ports 3/9-12 = vlan64
ports 3/13-16= vlan 256
This is what I did:
clear the configuration on the 6500
reset the 6500
set vtp to transparent mode
disable pruning
disable spaning tree
set up channel protocol on module 3 to LACP
set up 3/1-4 as lacp-channel
set up trunking on 3/1 and set it to on DOT1Q
setup 3 vlans as shown above
I connected a netware server running ANS (advance networking services) in ALB mode (2 nics using load balancing mode)
I am running netware IPX (four frame types) and also IP
when I do a show trunk, I see my trunk port being enabled on the 3 vlans,
My clients connect ocasionally, it takes many tries, but I may not connect at all.
If I take my clients and server to non cisco switch with vlans enabled, I am able to connect inmediately.
My Cisco will not be used for anything else, it is a simple setup.
Although my trunk port is shared among the 3 vlans, servers and client can not see each other.
Any advice from the gurus?

Do you have the MSFC (Multilayer Switch Feature Card)? You are going to need some kind of layer 3 funcionality to route between the VLANs.

no, I do not, my Vlans are within the same module and my clients and server are connecting in the same module.

Being on the same module will not allow different VLANs to see each other. Here are your choices.
1. Purchase the appropriate MSFC card for your switch to perform multlilayer switching.
2. Purchase an external router to perfrom inter-VLAN routing (although I'm not sure if this is support on the 6000's.)
3. Bridge between the VLANs, which basically defeats the purpose of creating VLANs anyway, which is to create separate broadcast domains.
4. Put all of the ports in the same VLAN.
Remember, VLANs are implemented at layer 2 of the OSI model, along with switching/bridging. In order for traffic to move between VLANs, which should be separate IP subnets, you need a device that operates at layer 3 of the OSI model. That means a router (MSFC).
