Native VLAN
Trunk ports on the network and power distribution module also support a Native VLAN. The Native
VLAN is where untagged frames will be allocated. On the network switch, the native VLAN is always the
Infrastructure VLAN. This allows client devices such as PCs or laptops to access and manage the
network switch when they are connected via a trunk port.
The Infrastructure VLAN is mandatory in the network switch and cannot be deleted.
An example of native VLAN functionality is illustrated in Figure 17: An example of native VLAN and
described below.
Figure 17: An example of native VLAN
1. The PC sends an untagged frame to Trunk port 3 on network and power distribution module
1.
2. The frame is allocated to the Infrastructure VLAN.
3. The management CPU of network and power distribution module 1 is always an Access port
on the Infrastructure VLAN and will receive the frame.
4. The untagged frame would also go to network and power distribution module 2 via the Trunk
ports between the network switch units.
5. network and power distribution module 2 allocates the untagged frame to the Infrastructure
VLAN.
6. The management CPU of network and power distribution module 2 is always an Access port
on the Infrastructure VLAN and will receive the frame.
