8. Use the Port Channel Load Balance
using a Source/Destination IP or a Source/Destination MAC as criteria. Source/Destination IP is the default setting.
9. Define the following Switching Mode
Mode 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.
Native VLAN Use the spinner control to define a numerical ID between 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.
Tag the Native Select the checkbox to tag the native VLAN. Access points support the IEEE
VLAN 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.
Allowed VLANs Selecting Trunk as the mode enables the Allowed VLANs parameter. Add
VLANs that exclusively send packets over the port channel.
10. Select OK to save the changes made to the port channel Basic Configuration. Select
configuration.
11. Select the Security tab.
Select either Half, Full or Automatic as the duplex option. Select Half duplex
to send data over the port channel, then immediately receive data from the
same direction in which the data was transmitted. Like a Full duplex
transmission, a Half duplex transmission can carry data in both directions, just
not at the same time. Select Full duplex to transmit data to and from the port
channel at the same time. Using Full duplex, the port channel can send data
while receiving data as well. Select Automatic to enable to the access point to
dynamically duplex as port channel performance needs dictate. Automatic is
the default setting.
