vlan

As far as I know in order to use two subnets on one physical cable VLAN's are recommended.

However, is it possible to achieve this (i.e: two subnets on one physical network)

like 192.168.1.0/24 and 10.0.0.0/8 networks.

What kind of problems or hidden rocks this way contains?

With VLAN's it's possible to better isolate so users wouldn't easly sniff the other network. But in my environment it's okay if user on one subnet could listen to the traffic on another network. Is it the only problem?

We have a existing class-c network with IP address range 11.22.33.44/24 (just for example). My domain controller has been configured within this subnet. So all servers within this subnet have subnet mask configured to 255.255.255.0. Now we have got a new subnet with IP address 11.22.88.99/24 (note… >>> More

VLAN ID 4095 for guest VLAN tagging

Just want to know if it's true that if you use the VLAN ID 4095 for guest VLAN tagging, then vMotion will not work correctly as there is nowhere to pass back the reverse arp to?
