A device is connected to a switch port, but the expected dynamic port profile is not applied. What is a common first step to troubleshoot this issue?

Disable the port and re-enable it

Change the port speed to a higher value

Reboot the switch to refresh the configuration

Verify that LLDP is enabled on the switch and the device

How are dynamic port profiles used to configure switch ports?

They are used only for access ports, not for trunk ports

They are stored locally on the switch and never updated

They are matched against detected devices, and the port is configured with the profile's settings

They are applied to all ports by default, regardless of the connected device

How does dynamic VLAN assignment work with RADIUS in a Mist-managed switch?

The VLAN is assigned based on the MAC address alone, without RADIUS

The VLAN is configured manually on the switch and cannot be changed dynamically

The RADIUS server returns a VLAN ID in the Access-Accept message, which the switch applies to the port

The switch assigns a random VLAN to the port after authentication

A company is planning to deploy dynamic port configuration across their network. They want to ensure that the configuration is consistent and can be managed centrally. What is a key benefit of using Mist for this?

Guaranteed network uptime with no configuration errors.

Automatic creation of VLANs based on device type.

Automatic firmware updates for all connected devices.

Centralized management of dynamic port profiles from the Mist portal, applied to all switches.

A user reports that their laptop is not getting the correct VLAN when connected to a switch port. The laptop is LLDP-enabled and the dynamic port profile for laptops exists. What should the admin check first?

Verify that the laptop's LLDP system name matches the profile's match criteria.

Ensure that the switch port is not administratively down.

Reboot the switch to refresh the LLDP cache.

Check if the laptop's Ethernet adapter is faulty.
