9. Use the Port Channel Load Balance drop-down menu within the Client Load Balancing field to define whether port
channel load balancing is conducted using a Source/Destination IP or a Source/Destination MAC as criteria. Source/
Destination IP is the default setting.
10. Define the following Switching Mode parameters to apply to the port channel configuration:
Speed Select the speed at which the port channel can receive and transmit the data. Select
either 10 Mbps, 100 Mbps, 1000 Mbps. Select either of these options to establish a 10,
100 or 1000 Mbps data transfer rate for the selected half duplex or full duplex
transmission over the port. These options are not available if Auto is selected. Select
Automatic to enable the port channel to automatically exchange information about data
transmission speed and duplex capabilities. Auto negotiation is helpful when in an
environment where different devices are connected and disconnected on a regular basis.
Automatic is the default setting.
Duplex 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.
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 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.
Tag the Native VLAN 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.
Allowed VLANs Selecting Trunk as the mode enables the Allowed VLANs parameter. Add VLANs that
exclusively send packets over the port channel.
