Hi~ Guys... Always thanks for your kind reply. I have some questions regarding the VLAN Secondary and switching performance. We're gonna change internal Lan Configuration, but we don't know exact network connection between hub(or switch) and hosts. Let's say... this host is connected which of switch or hub... They're using the Ethernet Secondary IP Address on their router... And so 2~3 of IP Address is mixed. If Secondary IP is applied in 1 of VLAN(1 of Network Segment), it's easy to migrate. In addition to this, I'm so afraid how about the switching performance when I adopted VLAN secondary IP. Let me wait for response from Switch Professional. Have a nice day... K.H KIM from Korea...
