A switch is configured to run STP. What term describes a field used to specify a VLAN ID?
- extended system ID
- port ID
- MAC Address
- bridge priority
| Explanation & Hint:
The term that describes a field used to specify a VLAN ID in a switch’s configuration, particularly in the context of Spanning Tree Protocol (STP) for VLAN-specific information, is “extended system ID.” The extended system ID includes the VLAN ID, which helps differentiate between different instances of the spanning tree protocol running on the same switch for different VLANs. This is commonly used in IEEE 802.1Q (VLAN tagging) and Rapid Spanning Tree Protocol (RSTP) for VLAN-specific spanning tree instances. |
