@george1421 Thanks for your support! Tested the dumb switch and… BINGO! You’re right. Mistery solved.
I’m actively studying for CCNA right now, so I understand the STP behaviour.
Next thing: redesign our network topology and reconfigure the cisco switch/es.

Regards!

@george1421 Thanks for your ultrafast response.
I will try to place a dumb swith and see the results.
Also I will try the image in /tftpboot/10secdelay/

Thanks!!

Hi guys,

Hope you can help me. My current network is slow getting DHCP leases. I suspect from STP, but right now I can’t reconfigure our switches.

Maybe it’s possible to increase the time to get a DHCP lease during the pxe boot?

Thanks!
