hi, We recently received the new 3850 switches and i try trunk vlan whit this command line, but for some reason is not work this is the config i use:

interface TenGigabitEthernet1/1/2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1701,1702,1710,1711,1721,1731,1738,1744,1754
switchport trunk allowed vlan add 1764
switchport mode trunk
channel-group 1 mode active

interface Port-channel1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1701,1702,1710,1711,1721,1731,1738,1744,1754
switchport trunk allowed vlan add 1764
switchport mode trunk

thank you.

Hi

Your config looks fine, could you please provide more details about the question? is the etherchannel down?

[wilfredo.rodriguez]

the situation when i config this command line (switchport trunk encapsulation dot1q) switch 3850 show error. but when i put this 

switchport mode trunk

switchport trunk allowed vlan 1701,1702,1710,1711,1721,1731,1738,1744,1754switchport trunk allowed vlan add 1764
switchport mode trunk
channel-group 1 mode active

on my switches 3750 work perfect, the last configuration i show first but in 3850

i not connected yet this switches on my network i just test in between by fiber optic cable here the photo

Ohhh I remember, the Cisco 3850 dont support that command because the trunks already work with 8021q implicitly.

switchport trunk encapsulation dot1q is not required on this model. The model does not support other trunking protocol than 8021q.

Hi,

Can you explain the topology and what is not working?

How are you testing?
