WS-C3750E-48PD etherchannel multi vlan

[GaarithKivijarvi96345]

what am i doing wrong? i can not get the vlans to go over my fiber port channel.

the no commands are what i want, and i have read should work. the rest is current running.

Not sure if i understand your question correctly here.

If you looking your VLAN to go across Port-channel you should allow them to span over.

as per your config, it is mode set to access, this act as access port.

change to below to work, make sure you shut the port-channel make the changes and enable back.

interface Port-channel1
description LAN trunk 20gb fiber
no switchport mode access
switchport mode trunk
switchport trunk encapsulation dot1q

switchport trunk native vlan 1

switchport trunk allowed vlan 1-200,1000

if this not what you looking explain more.

so i need to "shut the port-channel make the changes and enable back".

oh. i did not do that. i left the channel live the whole time. did not think i had to bounce it. i will try that.

what you see is two configs in one. i am "working" in the mode access right now.
the "no" commands are what i feel are the proper trunking set up, but dropped my vlans when i did them, but like i said... i did not bounce the channel.

make changes effective on best way do it always shutdown mode.

so follow below steps to make effective. (make sure you do it console, if your are not doing this config from management interface) - if not you loose connectivityt to switch.

config t

!

interface Port-channel1

shutdown

!

interface Port-channel1
description LAN trunk 20gb fiber
no switchport mode access
switchport mode trunk
switchport trunk encapsulation dot1q

switchport trunk native vlan 1

switchport trunk allowed vlan 1-200,1000

no shut

!

it should work as expected.

let us know the inputs.

Uhhhh ... whut?

It seems that your port-channel configuration is not correct:

try as:

config t

default interface TenGigabitEthernet1/0/2

default interface TenGigabitEthernet1/0/1

!

interface Port-channel1
description LAN trunk 20gb fiber
 no switchport mode access
 switchport trunk encapsulation dot1q

 switchport mode trunk

 switchport trunk allowed vlan 1-200,1000
 switchport trunk native vlan 1

interface TenGigabitEthernet1/0/1
description 10g fiber trunk 1 of 2
switchport mode trunk
channel-group 1 mode active
!
interface TenGigabitEthernet1/0/2
description 10g fiber trunk 2 of 2
switchport mode trunk
channel-group 1 mode active

when i shut the channels and then did the changes, and then no shut, it all worked. so use to just making live changes and did not think of the need to re provision the interface on the level 2. if was level 3 (ip address, route, gateway...) would not have been an issue.

thnks!
