When the evaluate configuration validator connects to a device it executes a "show run | in interface"-type command, then parses the output and presents a list of valid physical interfaces to the user to select from to perform validation.
If the output of "show run | in interface" has a physical interface at the top of the list, this first interface is not presented to the user in the next screen for selection. e.g.
switch3560#show run | in interface
interface FastEthernet0/1
interface FastEthernet0/2
interface FastEthernet0/3
interface FastEthernet0/4
interface FastEthernet0/5
interface FastEthernet0/6
interface FastEthernet0/7
interface FastEthernet0/8
interface GigabitEthernet0/1
interface Vlan1
interface Vlan2
interface Vlan191
interface Vlan999
-> Then interface FastEthernet0/1 will not be listed in the next screen when the user is to select which interfaces to validate the config for.
Conditions
This does not occur if the first interface listed in "show run | in interface" is a logical interface, e.g. loopback, tunnel etc.
