When the undercloud is installed, the networking is not being configured correctly.  If the tagged interface isn't set up correctly, I lose access to the AMM and subsequently the IMM of the individual blade.

The local_interface is the one used for PXE booting. After undercloud
installation you should see the br-ctlplane bridge created, containing
the local_interface and the local_ip set on top of the bridge.
Regarding the IPMI operations - you should see which interface is used
for reaching the IPMI address by checking the routing table ( ip r get

If you're using the PXE nic for reaching the IPMI network via tagged
frames then you could try the following workaround after undercloud
installation: add a tagged ovs port to the br-ctlplane bridge with the
right vlan tag and then assign it an IP address:

ovs-vsctl add-port br-ctlplane vlanX tag=X -- set interface vlanX type=internal
ip link set dev vlanX up
ip addr add x.x.x.x/x dev vlanX
