Clients on vlan5 and vlan150 have been getting an ip address for the dhcp server from vlan1 for quite some time. This morning nobody is able to get an ip address from the dhcp server at all. There have been no changes to the switch configuration. If I connect to a port in vlan1 I am able to get an address through dhcp. If I manually assign an address the client communicates to all vlans. The attached file is the config on the 3750 vlan switch. The switch on vlan 5 and 150 are Cisco SG500 switches in layer 2 mode.
