I have a couple SLM2024s that I need to configure with a few VLANS that allow communication between specific VLANS. I think I understand how to do this, except for the connection to the router. It is my understanding that I need to configure the port to the router as a Trunk port. However, I can't figure out how to do this in the SLM2024. Does it not support port trunking?
Edit: Or am I completely wrong in thinking I need to configure the port to the router as a trunk? Can I configure communication between VLANs without port trunking?
Removing VLAN 1is not something I would recommend. You can however enable filers that will require ingress traffic to have a tag, which will prevent VLAN 1 traffic from successfully passing. Please understand that the management IP address of the unit is on VLAN 1, and if you cut all access off for VLAN 1, you will render the switch (SLM) unreachable and a factory default reset will be required to make any changes.
VLAN1 is the only untagged VLAN (though you can break this rule if you must). All the other VLANs must be tagged. When the switch receives the frames, it must be able to differentiate which frames belong to which VLAN. It does this by looking at the number on the tagged frame. In the case of VLAN1, what makes it unique in the mind of a switch, is that it has no tag at all. In the case of these small business series devices, these untagged frames are then sent to the PVID of the switchport. So, while being an untagged frame is unique, it is not very descriptive and we must tell the switch exactly what to do with it.
I hope this helps. Let me know if I can clarify anything else.

WebEx sounds great. Our number here is 866.606.1866. You will need to have two things, your Cisco.com login ID (aka CCOID) and your serial number. You can ask for me directly if you wish.
