How to create 2 VLANs on L3 Switch w/ External DHCP?

by devdevil85 . Updated 18 years, 6 months ago

Do anyone know the commands necessary for implementing this type of scenario or even better does anyone have a sample configuration that resembles this type of setup for me to use?

My Scenario:

2 VLANs (VLAN1 & 10)
1 port belonging to VLAN10 (Port 22)
1 L3 Switch (Cisco 3560)
1 External DHCP Server (Win2003)

These are the commands that I know I need to use and have used so far w/ still no luck:

ip routing (enables L3 routing)
switchport access vlan 10 (on port 22)
switchport mode access (on port 22)
ip address 192.168.1.7 (ip add for VLAN1)
ip address 192.168.10.1 (ip add for VLAN10)
ip helper-address 192.168.1.1 (DHCP relay for VLAN10)
ip route 0.0.0.0 0.0.0.0 192.168.1.15 (default route)

These are the commands I have used so far. I have also created the scopes necessary for the VLAN10 subnet on the DHCP server as advised, yet when I plug in my laptop to port 22 I am unable to obtain an ip address and cannot proceed further to test communication between the VLANs w/o a network address.

What am I doing wrong/missing?

Please help as I am confused on what else to do.

A sample working configuration would really be ideal as I could compare it to my setup so far.

Thanks!
