I have a situation where DHCP leases and other serivces are a lot slower than the services that are requested from an IP phone. When plugging the computer directing into the port the computer gets an IP 10 to 15 secs slower than if the computer is plugged into the IP phone which is then plugged into the floor port.
Systems plugged into the phone can also netboot (OSX) while systems plugged directly into the port can not
I have qos configured on all ports, but do not have this situation on other switches that are configured the same way. Example of configs:
2 questions. Do you have the ip helper-address configured on the L3 SVI for the access vlan? Does the port go active immediately upon plugging in the computer directly to the port? Wondering if portfast is not working correctly since there is a voice vlan configured. You can test this by giving the PC a static IP and seeing if it's actually waiting on DHCP or if the port is not actually going active (ie. the port is waiting on spanning tree checks before going active)
