I need confirmation of the "switchport access vlan" command below when the interface is configured as a trunk.
If a PC is connected to this interface, and it isn't trunking, traffic will be sent on VLAN 53 (Native)... right?
so, therefore, the "switchport access vlan 600" isn't being used? or does it serve another purpose when the interface is configured as a trunk?
(i know what the command does when the interface is configured as an access port)
switchport access vlan 600
switchport trunk encapsulation dot1q
switchport trunk native vlan 53
switchport trunk allowed vlan 53,600
switchport mode trunk
thanks in advance.
You have the command
"switchport mode trunk"
which means the switch will form an unconditional trunk. Even if the connected device does not support trunking, the switchport will be in trunk status. The connected device will discard the tagged Vlans if trunking is not supported but it will be able to connect by using the native Vlan which is untagged.
On your example, the connected device is using Vlan 53 and not Vlan 600 and having 'access vlan 600' serves no purpose.
