Yes in the table means the VLAN is set on the roamed-to WX, by the mechanism indicated by the column header. No means the VLAN is not set. Yes or No means the mechanism does not affect the outcome, due to another mechanism that is set.

The VLAN Assigned By column indicates the mechanism that is used by the roamed-to switch to assign the VLAN, based on the various ways the VLAN is set on that switch.

„Location Policy means the VLAN is assigned by a location policy on the roamed-to switch. (The VLAN is assigned by the vlan vlan-idoption of the set location policy permit command.)

„AAA means the Vlan-name attribute is set on for the user or the user’s group, in the roamed-to switch’s local database or on a RADIUS server used by the roamed-to switch to authenticate the user. (The VLAN is assigned by the vlan-namevlan-idoption of the set user attr, set usergroup attr, set mac-user, or set mac-usergroupcommand.)

„keep-initial-vlanmeans that the VLAN is not reassigned. Instead, the VLAN assigned on the switch where the user first accesses the network is retained. (The keep-initial-vlanoption is enabled by the set service-profilename keep-initial-vlan enable command, entered on the roamed-to switch. The name is the name of the service profile for the SSID the user is associated with.)
