In a Cisco wireless network, an engineer needs to connect a device to a switch to support multiple wireless networks, each associated with different VLANs. Which switch port configuration provides the BEST setup in this scenario?
Configure the switch port as a routed port
Configure the switch port as a port-channel with LACP
Configure the switch port as an access port in the native VLAN
Configuring the switch port as a trunk port is the best choice because it allows the port to carry traffic for multiple VLANs simultaneously. This is necessary when the connected device, such as an access point, needs to handle multiple wireless networks (SSIDs) that are mapped to different VLANs. Trunk ports enable the transmission of frames tagged with different VLAN identifiers, facilitating proper VLAN segregation and traffic handling.
An access port in the native VLAN would only carry untagged traffic for a single VLAN, which is insufficient for supporting multiple VLANs. Configuring the port as a port-channel with LACP focuses on link aggregation for increased bandwidth and redundancy, which does not address the need for multiple VLAN support in this context. A routed port operates at Layer 3 and disables Layer 2 switching capabilities, making it unsuitable for VLAN tagging and switching required by multiple SSIDs.
