8. Use the Port Channel Load Balance
channel load balancing is conducted using a Source/Destination IP or a Source/Destination MAC as criteria. Source/
Destination IP is the default setting.

11. Select the Security
drop-down menu within the
Switching Mode parameters to apply to the port channel configuration:
Select either the Access or Trunk radio button to set the VLAN switching mode over the port
channel. If Access is selected, the port channel accepts packets only form the native VLANs.
Frames are forwarded out the port untagged with no 802.1Q header. All frames received on the
port are expected as untagged and are mapped to the native VLAN. If the mode is set to Trunk,
the port channel allows packets from a list of VLANs you add to the trunk. A port channel
configured as Trunk supports multiple 802.1Q tagged VLANs and one Native VLAN which can
be tagged or untagged. Access is the default setting.
Use the spinner control to define a numerical ID from 1 - 4094. The native VLAN allows an
Ethernet device to associate untagged frames to a VLAN when no 802.1Q frame is included in
the frame. Additionally, the native VLAN is the VLAN which untagged traffic will be directed
over when using trunk mode. The default value is 1.
Select this option to tag the native VLAN. Access points support the IEEE 802.1Q specification
for tagging frames and coordinating VLANs between devices. IEEE 802.1Q adds four bytes to
each frame identifying the VLAN ID for upstream devices that the frame belongs. If the
upstream Ethernet device does not support IEEE 802.1Q tagging, it does not interpret the
tagged frames. When VLAN tagging is required between devices, both devices must support
tagging and be configured to accept tagged VLANs. When a frame is tagged, the 12 bit frame
VLAN ID is added to the 802.1Q header so upstream Ethernet devices know which VLAN ID the
frame belongs to. The device reads the 12 bit VLAN ID and forwards the frame to the
appropriate VLAN. When a frame is received with no 802.1Q header, the upstream device
classifies the frame using the default or native VLAN assigned to the Trunk port. The native
VLAN allows an Ethernet device to associate untagged frames to a VLAN when no 802.1Q
frame is included in the frame. This setting is disabled by default.
Selecting Trunk as the mode enables the Allowed VLANs parameter. Add VLANs that
exclusively send packets over the port channel.
