Port Channels Switching Configuration

About this task

Define a port channel's switching configuration.

Procedure

  1. Select Profiles > Profile Name > Interface > Port Channels > Switching.
  2. Define the following Switching parameters to apply to port channel configurations:
    Mode Use the Mode drop-down list box to select Access or Trunk mode to set the VLAN switching mode over the port channel
    • Access - 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
    • 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 mode is the default setting
    Native VLAN Use the spinner control to define a numerical ID between 1 to 4,094. 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
    Native VLAN Tagged Select Native VLAN Tagged to tag the native VLAN. WiNG managed devices 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
    Allows VLANs Selecting Trunk as the mode activates the Allows VLANs parameter. Set VLANs between 1 and 4,094
  3. Select Save to update port channel switching configuration.
