My client's office has two floor. Each office uses Linksys switches.
I'm planning to put one L3 H3C 5500 series to connect these switches.
#1. Main office will have two VLAN - one VLAN (100) for servers connect directly to the L3 switches, and another VLAN (200) for connecting the Linksys switches. After, devices in these two VLAN should be pingable to each other even though the Linksys don't support VLAN, correct ?
#2. The other floor will connect to the L3 switch through CAT5E and connect to L3 switch through a physical port binded with VLAN 300. After the connecting, these 3 floors will be pinable to each other, correct ?
#3. In case the 2nd office has two subnet, does it mean either one of the subnet can be tagged by the VLAN ? Is it possible for a single VLAN to support two different subnet ?
#4. Is there any maximum number of device supported by a VLAN ? 500 devices based on the below article, correct ?
"The number of Ethernet addresses than can be supported by each device is 500. This is a distribution of about 20 devices per port on a 25 port switch. In an ideal network situation, there is one device per port, for example, a printer, a workstation, and voice IP phone will require 3 ports. If you wanted to have one VLAN assignment for each port, then the maximum VLANs will equal 25."
