What I did
Avoid removing the subinterface when last configured ip is removed
How I did it
In case of other interface types like INTERFACE, VLAN_INTERFACE, PORTCHANNEL_INTERFACE, when the last ip address is removed the CLI implicitly delete the interface table entry of type INTERFACE|intf_name. However this logic doesn't apply to VLAN_SUB_INTERFACE since the creation and removal will be controlled by config subinterface command
Without this fix the subinterface gets removed and show subinterface status will not list the subinterface.
How to verify it
Added UT to verify it.
Previous command output (if the output of a command-line utility has changed)
New command output (if the output of a command-line utility has changed)
