Description: Indicates if the port is actually trunking or not. In the case of ISL capable ports, the status depends on the success or failure of the negotiation process initiated by the port to become a trunk or non trunk. In the case of 802.10 capable ports, it is directly related to the on/off administrative status.

What is vlanPortIslOperStatus?

This read-only object reports whether a port is actually operating as an ISL trunk, based on the outcome of trunk negotiation for ISL-capable ports.
