Comprehensive Explanation: The interface configuration shows that VLANs 2, 3, and 100 are tagged, meaning frames belonging to these VLANs are transmitted with VLAN tags. VLANs 4 and 6 are untagged, meaning frames for these VLANs are transmitted without tags. The command port hybrid tagged vlan 2 to 3 100 specifies that data frames for VLANs 2, 3, and 100 are transmitted with tags, while port hybrid untagged vlan 4 6 configures the interface to transmit untagged frames for VLANs 4 and 6.

Comprehensive Explanation: In STP (Spanning Tree Protocol), ports can be in several states, including:

Discarding: The port is not forwarding traffic, either because it is in a blocking state or not participating in active forwarding.

Listening: The port is processing BPDUs and is preparing to transition to either the learning or forwarding state. No data frames are forwarded during this state.

Forwarding: The port is actively forwarding traffic as part of the active network topology.

The "Disabled" state is not part of the STP protocol but rather represents a port that is administratively shut down or not participating in the STP process.
