9. Set or override the following port channel Properties:
10. Use the Port Channel Load Balance drop-down menu from the Client Load Balancing section to
define whether port channel load balancing is conducted using a Source/Destination IP or a
Source/Destination MAC. Source/Destination IP is the default setting.
11. Define or override the following Switching Mode parameters to apply to the port channel
configuration:
12. Select OK to save the changes and overrides to the port channel Basic Configuration. Select
Reset to revert to the last saved configuration.
13. Select the Security tab.
Description Enter a description for the controller or service platform port channel (64 characters maximum).
Admin Status Select the Enabled radio button to define this port channel as active to the profile it supports. Select
the Disabled radio button to disable this port channel configuration in the profile. It can be activated at
any future time when needed. The default setting is enabled.
Speed Select the speed at which the port channel can receive and transmit data. Select either 10 Mbps, 100
Mbps or 1000 Mbps to establish a 10, 100 or 1000 Mbps data transfer rate for the selected half duplex
or full duplex transmission. These options are not available if Auto is selected. Select Automatic to allow
the port channel to automatically exchange information about data transmission speeds and duplex
capabilities. Auto negotiation is helpful 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 controller or service platform 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 from the native VLAN. Frames are forwarded
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 Native VLAN 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 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. Controllers and service platforms 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, a 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.
