We are having some difficulties using PXE in our Cisco environment. Currently, we are in the process of setting up Micorsoft Comfig Manager to deploy images. All devices are connected via Catalyst 6509E with multicast routing enabled. We have our DHCP server setup up in vlan 100. Our PXE server and workstations to be imaged are setup in VLAN 180. Portfast is configured on all ports connecting to machines. IP helper adress is configured on vlan 180 to point to our dhcp server. When PXE boot is initiated on workstation in vlan 180, network boot immediately fails with "media dsconnected" error message. However, when booting to removable media, workstation pulls dhcp address and finds PXE server to image workstations.
Is there anything on the switch that needs to be configured for network boot to work? I do not know much about configuration of PXE on switches. Can someone point me in the right direction? Thanks in advance.
