mode for a port that is connected to an end device such as a printer, media device,
or computer. When a port that functions in access mode receives data that is
untagged, the data is delivered normally. When a port that functions in access mode
receives data that is tagged for a VLAN other than the one the port belongs to, the
data is discarded.
Trunk mode. A port that functions in trunk mode automatically belongs to all VLANs
on the access point and tags the traffic that it processes. You would typically use
trunk mode for a port that is connected to another network device. For example,
you would assign trunk mode for an uplink to a switch or router and for a downlink
to another access point. By default, port 1 functions in trunk mode as an uplink. For
a LAG connection, you must also assign trunk mode to the LAN 2 port.
A default port VLAN ID (PVID) is a VLAN ID tag that the access point assigns to incoming
data packets that are not already addressed (tagged) for a particular VLAN. For example,
if you connect a computer to port 2 of the access point and you want it to be a part of
VLAN 1, add port 2 as a member of VLAN 1 and set the PVID of port 2 to 1. This
configuration automatically adds a PVID of 1 to all data that the access point receives
from the computer and makes sure that the data from the computer on port 2 can be
seen only by other members of VLAN 1. You can assign only one PVID to a port.
Change the port mode or port VLAN ID for a port
A port can function in trunk mode or access mode.
By default, port 1 functions in trunk mode as an uplink. Port 2 functions in access mode
as a downlink. By default, both ports are untagged members of VLAN 1, that is, their
PVID is 1. If you enable link aggregation (see Enable link aggregation for the LAN 2 port
on page 169), make sure that you configure port 2 to function in trunk mode.
Note: All WiFi ports function in access mode. You cannot change the port mode for a
WiFi port.
To change the port mode or port VLAN ID (PVID) for a port:
1.
Launch a web browser from a computer that is connected to the same network as
the access point or directly to the access point through an Ethernet cable or WiFi
connection.
2. Enter the IP address that is assigned to the access point.
A login window opens.
If your browser does not display the login window but displays a security warning,
dismiss the warning. For more information, see Dismiss a browser security warning
on page 43.
3. Enter the access point user name and password.
