i'm trying to set up a dhcp server on my gs648p running layer 3. nothing gets a lease from it.

this is my log

Hi Frank,

 

With your new config it should work. I have just tested it and it worked as you can see below:

vlan 1 name DEFAULT-VLAN by port

 router-interface ve 1

!

 tagged ethe 1/1/1

 router-interface ve 10

Please remove the no port bootp from the config as that it’s blocking the bootp packets and DHCP won’t work. (you need to enter “port bootp”)

 

0d00h02m33s:A:DHCPS: unable to find an address pool for rx port 1, dropping DHCPOFFER message ---->  Indicates that the DHCP service was unable to match an address pool for the interface where the DHCP discover was received.

 

0d00h00m26s:W:DHCPS: Failed to read lease-binding database to flash ---> shows up when the DHCP server is stopped you will need to deploy it each time when you make any changes in the DHCP pool

 

I suggest removing DHCP snooping and try it. There is an old defect in the version that you are running (ver 07.2.02a) that causes the DHCP Discover packet to not be broadcasted within the incoming VLAN, which most likely why it’s not working for you . The recommended version from the FGS that has the fix for this is ver 07.2.02r


Thanks

 






thanks but my new config doesn't have  the no bootp option. also i changed the pool 10 192.168.10 rather than 11 which now matches ve10 ip. still not working though. 

Please update your code to 07202r.

From above config we see no port bootp just above the eth 0/1/25,

no port bootp
interface ethernet 0/1/25
dual-mode

Do you have the DHCP client directly connected to the switch? have you ran a pcap to see if the DHCP Discover into the switch?

Thanks,

that's odd. i did not port that in. How do i turn that off?  and how do i update my code to 07202r. ?

To remove the no port bootp from the config you need to enter “port bootp”
