John,
I believe you can create very specific ignore rules that will do this. Try adding these rules:
^interface Vethernet7
^inherit port-profile SYSTEM-VLAN301
^description UOS-BBAS-03,Network Adapter 1
^vmware dvport 3250 dvswitch uuid "56 7d 0d 50 91 52 54 fc-77 36 65 dd 2c 7f 54 05"
^vmware wm mac0050.568D.059E
These 5 rules will only ignore lines that begin with this specified text. However I do not know if this will work for you being that these interfaces are being created and destroyed dynamically. For example this first ignore rule will only ignore lines that begin with "interface Vethernet7" If it is a Vethernet8, that would not be ignored.
