I have a small network with just a few Cisco SB switches devided by a few VLANs. One of the swithes performs Inter-VLAN routing and also acts as a DHCP Relay. DHCP server is connected directly to the core switch.
The problem is that it may take long time for end-devices to take an IP address from DHCP server. Sometimes it take just a moment, but sometimes take a few minutes.
The problem is not in STP beacuse wireless clients also expirience this issue.
I took a capture from a client side and from the server simultaneously. The results you can see in the attachment. The capture shows that two first DISCOVER packets from the client didn't get to the server.
