router dhcp problem

[Jangelides]

Hi guys, currently learning CCNA. Stuck with a small probem. I have a 1760 Router that I have configured as a DHCP server to the VLAN's on my switch. I have followed all the instructions that I have found but unfortunately the switch is just not getting assigned the ip addresses.  Can anyone help me please.

Here is my router config

Again thank you so much.  Would have taken me forever to spot that.  Hopefully.....on day.......i get to be half as good as some of guys on here. One hurdle complete 1001 lef to go.

Port 1 in my switch which is in native vlan 1 is connected to fa0/0 on the router.

Not sure what you mean by this ie. the port should be configured as a trunk.

Which specific port on the switch connects to the router ?

Also which port is the client connected to ?

Jon

Sorry my mistake. fa0/1 on the switch is configured as a dot1q trunk and connected to fa0/0 on the router.  The client pc is connected to fa0/2 on the switch which is configured as an access port and in vlan10.

I just checked your switch configuration. you need to assign an IP address to each SVIs. Assign .2 IP address on each SVI.

ROUTER <----> SWITCH

Router will be tagging VLAN 10,20,30 traffic and using .1 IP address

Your switch also needs to tag the traffic and send it to Router using SVIs.

Also, do not use 'ip default-gateway' -> this is for L2 switch

Use 'ip route 0.0.0.0 0.0.0.0 next-hop' for L3 switches

Thanks,

The router is doing the inter vlan routing not the switch so -

1) the SVIs should be left shutdown and do not need IP addresses

2) you should use "ip default-gateway" because the switch is acting as a L2 switch and not L3

I realised that and removed the IP helper-address commands. I did set the default gateway to 192.168.1.1 which is the IP address of fa0/0.1 on the router.

My equipment consists of a cisco 1760 router and a cisco layer '2' switch, so svi's are not an option.
