Native VLAN configuration on WNM using Switch 14-24FPOE

05/22/2024 4 People found this article helpful 87,666 Views

Description

When an untagged packet enters a switch port, it gets linked with the Native VLAN (Port VLAN ID) and sent to a VLAN determined by the VID within that Native VLAN.

Consequently, a packet received on a specific port inherits the Native VLAN of that port and is then routed to the port corresponding to the packet's destination address.

If the Native VLAN of the receiving port differs from that of the transmitting port, the switch will discard the packet. Different Native VLANs within the switch signify different VLANs, hence VLAN identification based on the Native VLAN cannot extend VLANs beyond the boundaries of a single switch.

If no VLANs are defined on the Switch, all ports are then assigned to a default VLAN with a NATIVE VLAN equal to 1.

To enable Native VLAN functionality on the WNM, the following requirements must be met:

All ports must have a defined Native VLAN.
If no other value is specified, the NATIVE VLAN is used.
If you wish to change the port’s default NATIVE VLAN, you must first create a VLAN that includes the port as a member.

NATIVE VLAN

Enter the Native VLAN value. The range is from 1-4094.

Accept Type

Select Tagged Only and Untagged Only from the list.

1. Tagged Only: The port discards any untagged frames it’s receives. The port only accepts tagged frames.

2. Untagged Only: Only untagged frames received on the port are accepted.

3. All: The port accepts both tagged and untagged frames.

Ingress Filtering

Specify how you wish the port to handle tagged frames. Select Enabled or Disabled from the list.

1. Enabled: tagged frames are discarded if VID does not match the NATIVE VLAN of the port.

2. Disabled: All frames are forwarded in accordance with the IEEE 802.1Q VLAN.
