Vlan-Trunking - Edge-Core ECS4210-12P Reference Manual

the PVID for an interface can be set to any VLAN for which it is an untagged
member.
◆
If acceptable frame types is set to all or switchport mode is set to hybrid, the

Example
The following example shows how to set the PVID for port 1 to VLAN 3:
Console(config)#interface ethernet 1/1
Console(config-if)#switchport native vlan 3
Console(config-if)#

The following figure shows VLANs 1 and 2 configured on switches A and B, with
VLAN trunking being used to pass traffic for these VLAN groups across switches
C, D and E.
Figure 3: Configuring VLAN Trunking
Without VLAN trunking, you would have to configure VLANs 1 and 2 on all
intermediate switches – C, D and E; otherwise these switches would drop any
frames with unknown VLAN group tags. However, by enabling VLAN trunking
on the intermediate switch ports along the path connecting VLANs 1 and 2,
