      Hi. I have a number of APC PDU's on the untagged management interface that I now want to put on a new VLAN (VLAN 150). For some reason the clients wern't showing up on the new VLAN when I unplugged them and reconnected them.

      I reconfigured the switch ports to make the new native VLAN be VLAN 150, and then unplugged the cables and plugged them back in.

      Here is the DHCP log of one of them (they are all being treated the same way):

      May 24 10:44:35 dhcpd DHCPREQUEST for 10.1.1.252 from 00:c0:b7:b8:a5:82 via vmx0.150
      May 24 10:44:35 dhcpd DHCPACK on 10.1.1.252 to 00:c0:b7:b8:a5:82 via vmx0.150

      vmx0 is the main trunk (PFsense is running on vmware as a guest, and vmware is configured the interface as a trunk carrying all VLANs).

      vmx.150 is the interface to VLAN 150. This PDU was previously on the management interface, which is the 10.1.1.0/24 subnet. VLAN 150 is supposed to be subnet 10.1.150/24.

      Why is the DHCP server on that interface not NAK'ing the old address and issuing a new address on the 150 subnet?

      thanks,
      mike
