Applying no IP route-cache on VLAN interfaces in a Layer 3 switch
Is it necessary to apply no IP route cache on virtual local area networks (VLAN) interfaces in an L3 switch and why? What are the advantages or disadvantages?

What is a non-routable VLAN? Why would you use one?
I've heard the term "non-routable VLAN" but am not sure what exactly it means, why it exists or when it's used. It would seem perhaps just by definition that it's an existing virtual local area network (VLAN) that just doesn't have a VLAN interface created for it anywhere on purpose. Do you use it...

Reconfiguring network switches as 802.1q VLAN trunks for VMware ESX implementation
My data center network switches are configured as access ports, but we are soon implementing VMware ESX. Is there an easy way to reconfigure the switches to operate as 802.1q VLAN trunks to take advantage of VMware's VLAN management support?

Can two switches, having VLAN defined in each, communicate without the help of Layer-3 device?
If in a single L2 Switch, IPs of the same range can communicate - then what's the need of creating a VLAN for different IP range? Can two switches (having VLAN defined in each) communicate without the help of Layer-3 device? Thank you.

Associate Vlan with subnet
Hi, I can't figure out how to associate a VLAN with a Subnet. For subnets you need to have a router in between. For VLAN's trunking...but how do I associate these 2 so when a port on the switch is change from VLAN 1 to VLAN 2 to get IP address from a different subnet DHCP. Thank you!
