Description (partial)

Symptom:
When Gig1 is configured on CSR and it is also used as the management ip, if we try to configure sub-interface Gig1.1, it gets configured as "native" by default( even without using the keyword "native"):-
Router(config)#int gig1.1
Router(config-subif)#encapsulation dot1Q 1
Router(config-subif)#

At this point, the telnet session is lost and so is the connectivity with pnsc. When I login using Vsphere and check the config, it shows gig1.1 is configured as native sub-interface. As follows;-
interface GigabitEthernet1.1
encapsulation dot1Q 1 native

Conditions:
Configure Gig1.1 when Gig1 is configured
