My new LAN wil have 37 Catalyst switches (02 Cat 6505, the backbone).
I am considering to create 04 vlans. Questions :
Should each VLAN use different subnetworks ?
Which Vlan my DHCP server must be placed into ?
How does the DHCP server know what IP address to assign according to the vlan? I mean, if a PC in vlan 1 sends a broadcast, DHCP server must give it , let´s say, 126.96.36.199 , if PC belongs to vlan 2, gives 188.8.131.52, and so on.... is it a router config issue or DHCP one ? How ?
Should server farm have a different subnet and vlan than the one for PC clients ?
Yes, you need each VLAN in a different subnet. The DHCP server can be in any VLAN. Just set up multiple scopes for all the VLANs you have and use the helper addresses on VLAN interfaces to forward the DHCP broadcast across VLANs. Regarding server farm being in a different subnet, it's not a neccessity but more of a design issue
Thanks for your help. I have created interface vlan 1, 2 & 3 in some switches, using helped addresses,but vlans 2 & 3 are shutdown; when I do "no shutdown" and then show runn... interfaces are still shutdown....
