VLAN

tonydotigr

Can VLANs utilize packet filtering to enhance network security? My inital guess would be NO, because this is a layer 2 device it only works with frames.

I believe the following are true in regards to VLANS?
- establish broadcast domains in switched networks
- all access to network services based on dept. not location
- can greatly simplify adding, moving, or changing hosts in a network

TIA

You are right, VLAN's can NOT utilize packet filtering as they are implemented on Layer 2. Packet filtering can only be used if VLANs get interconnected through a Layer 3 device (e.g. a router).

Your summarization of VLAN capabilities is also correct.
