Dot1q termination vid 10什麼意思

"dot1q termination vid 10" is a networking term that refers to the configuration of 802.1Q VLAN termination with a VLAN ID (VID) of 10. Let's break down the terminology:

• dot1q: This is a shorthand for IEEE 802.1Q, which is a protocol for virtual LANs (VLANs). 802.1Q is used to tag frames with a VLAN identifier so they can be routed appropriately within a switched network.

• termination: In the context of VLANs, termination refers to the process of removing the VLAN tag from a frame when it reaches its final destination. This is typically done at the edge of the network, where the switch connects to an end device.

• vid: Short for VLAN ID, which is a number used to identify a specific VLAN. Each VLAN needs a unique identifier to ensure that traffic is properly segregated and routed within the network.

• 10: This is the VLAN ID number. In this case, the VLAN that is being terminated is VLAN 10.

So, "dot1q termination vid 10" means that the switch is configured to remove the 802.1Q VLAN tag from frames that belong to VLAN 10 when they reach the switch port that is configured as the access port for VLAN 10. This allows the untagged frames to be forwarded to the connected device, which is typically a host or another network device that is a part of VLAN 10.
