  • How do assign dhcp ipaddress to vlans

    Here in my company ip was assigned to all systems by DHCP server.if we need to change the ip address then we need to change the switch port to concern VLAN. Here my doubt is how the VLANS are assinged to take the particular ip range from DHCP Server ? how do we configure that ?

    Configure multiple scopes on the DHCP server.
    Assign an IP-helper address per VLAN to the DHCP server.

      Just one command on your switch.

      int vlan x
      ip helper-address (your DHCP server ip)


      rest Mr.Dumber said you also need to create scope in your DHCP server .

        for example

          While creating scope in your DHCP server ,you have to mention VLAN ID,IP ADD,S/B MASK,GATEWAY and also how many host you want to add .

          All you need to define in your DHCP server for each VLAN .
