这是一个Cisco交换机接口的配置命令,用于设置接口的工作模式为“动态协商优先(dynamic desirable)”,也就是说,接口会首先尝试与对端设备进行动态协商,如果对端设备支持动态协商,则接口会自动选择最优的工作模式进行通信,如果对端设备不支持动态协商,则接口会自动降级为静态访问模式(access mode)。这种配置方式可以在保证灵活性的同时,最大限度地提高网络的性能和可靠性。

switchport mode trunk
This command is used in Cisco networking to configure a switchport to operate in trunk mode. Trunk mode is used to carry traffic from multiple VLANs over a single physical link between switches.
When a switchport is configured to operate in trunk mode, it can carry traffic from multiple VLANs simultaneously by tagging the traffic with a unique VLAN ID. This allows the switch to distinguish between different VLANs and forward the traffic to the correct destination.
To configure a switchport to operate in trunk mode, the command "switchport mode trunk" is used. This command is entered in interface configuration mode for the switchport that needs to be configured. Once the command is entered, the switchport will be configured to operate in trunk mode and will be ready to carry traffic from multiple VLANs.
switchport mode access
"switchport mode access" is a command used in Cisco networking devices to configure a specific interface as an access port. An access port is a port that connects an end device such as a computer or printer to a switch. This command sets the interface to operate in a mode where it only transmits and receives untagged frames, which are frames that do not have any special VLAN tagging attached to them. This mode is commonly used for devices that do not need to communicate with other VLANs on the network.
