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

Hello Frank,

Please remove the “no port bootp” from the config and check it again.

Can you have DNS-Server and DHCP-Default-Router 192.168.1.4, on the 192.168.11.0/24 subnet?

Hi Frank,

 

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

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,

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

 

Here is the link to download the code the https://support.ruckuswireless.com/software?filter=125#firmwares

 

Ruckus FastIron code 07.2.02r applies to your GS648P

I don't know what a GS-648P switch is, but Brocade "gave" Ruckus the old Foundry lines of FastIron CX, SX, WS, EdgeX, and TurboIron but not any "GS" line.

The lowest version of FastIron firmware we provide is 7.3 so no 7.2.x is available from Ruckus.  We don't officially support your product it seems, so all hope
must come from previous Brocade way back folks, if any are here, thanks.

The FGS is an older Foundry switch model that is EOL.   The 7.2.x code train is the latest version that can run on it.  Mohand who has already responded on this thread is one of our TAC engineers.   I recommend that you continue to work with him and follow his guidance.

funny. i remove the no port bootp from the config. save it and when i restart it's back again. wierd. On the plus side recabling fixed the dhcp problem. i wouldn't mind the 7.2 formware but you can only get that with a premium account. I don't know how much that is and as i'm en employee for the company that owns this box. i would have to put it past them.
