In the example above:
- `Last State Change` shows the timestamp of the last operational state change.
- `Total State Changes` shows the total number of transitions in carrier state.
- `Total State Changes` shows the total number of transitions in the carrier state.
- `Up Count`shows the number of times the carrier transitioned to an UP state.
- `Down Count` shows the number of times the carrier transitioned to a DOWN state.

To show the date and time the operational state of a specific interface changes (`oper-status-last-change`) and the number of carrier transitions (`carrier-transitions`, `carrier-up-count`, `carrier-down-count`):

To show the number of carrier transitions only (`carrier-transitions`, `carrier-up-count`, `carrier-down-count`) for a specific interface, run the `nv show interface <interface> link stats` command.
