Hi, I was wondering whether someone could help  me. In my network setup I use, at least, two VLAN's in a Virtualized model. That is... I have each workstation with a Virtual Machine inside it. The host machine, is in  VLAN Id 76 and the VM uses default VLAN. Each VLAN has a separate DHCP server. The interface definition for the tagged VLAN is as follows interface GigabitEthernet1/0/11 switchport access vlan 76 switchport trunk encapsulation dot1q switchport mode access priority-queue out spanning-tree portfast ! The NIC on the server has no definition for setting a VLAN, mostly because the server hasn't the latest Intel driver. Anyways I'm not sure that it is because of that... What happens? Everytime I turn on the computer, it takes more than a minute to assign an IP to the workstations. The same doesn't happen on the Virtual Machines... the VM's use the default VLAN... The workstations have the following setup: interface GigabitEthernet1/0/40 switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,4,76 switchport mode trunk switchport voice vlan 4 priority-queue out mls qos trust device cisco-phone mls qos vlan-based spanning-tree portfast Might there be any config in my 3750 that can help improve the time that the DHCP takes to deliver an IP to the workstations? Thanks in advance. Nuno Silva ... View more
