A controller is connected to a Cisco Catalyst switch. The switch port configuration looks like this:
interface GigabitEthernet 1/0/10
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,20,30,50
switchport trunk native vlan 20
switchport mode trunk
Which controller CLI command assigns its management interface to the native VLAN interface of the Cisco Catalyst switch?
A.
config interface vlan management 0
B.
config interface vlan management 1
C.
config interface vlan management 20
D.
config interface vlan management 30
E.
config interface vlan management 50
Explanation:
seen this on three diff test question sources. Each with a different answer.
And this is the correct one: the traffic should be untagged (so vlan 0)…
how can it be vlan 0? for a start its not allowed on the trunk and the command “switchport trunk native vlan 20” specifically sets the native i.e. untagged vlan as 20?
If you wanna your managment traffic running untaged in Vlan 20, set Vlan 20 as native and on Controller side set ” config interface vlan management 0″ it means untaged.
You mean to say Traffic goes from WLC NAtive 0 [default] to Swtich trunk and on switch its NAtive vlan 20 .
Mean different Native VLANs on both side [WLC -Switch], Right ????
And one thing more do we have to allow Native vlan on trunk?
