Vlan in statck

dellpe

Im trying to get all my vlans to pass thru to my huawei S3700-28TP-EI-AC user level switches, from my 3750 stack.
Each one of my s3700 stack is connected to my 3750 via port channel. Here is my port setup.
I have Vlans 1,210,214,216,220,306,406 on my 3750 stack. I cannot see those vlans on my s3700 stack. Why is that? What am I missing from the config?
Thanks...

3750 ports:

interface GigabitEthernet1/0/41
description Uplink to ETHSW03
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,210,214,216,220,306,406

I have never messed with a that vendor switch before (huawei) but does your 3750 see the trunk?

"sh int trunk"
what do you see ?

also..once again never messed with huawei but if its anything like a normal L2 edge switch you most likely have to define the vlans on the switch before they will work for example on any cisco switch serving as a L2 device the command from global...

vlan 210
name fart_box
vlan 214
name Smug_mouse
vlan 216
name who_farted

this has to be done before I can use them...even if I have them allowed on a trunk to my L3 device or another L2 device I am daisy chained off of ( which is a rubbish idea )

hope that helps...

2 things:
-If your native vlan is 1, you don't need to put it in the switchport trunk allowed vlan command. It is untagged unlike your user vlans.
-As vahokie said, to enable the vlans, you need to input the vlan # command to enable it. Lol and you can give it those names as well.

and make sure your VLANS are in STP correctly (Show spanning-tree VLAN "insert name / number here"). I had this issue recently for certain testing equipment (Forgot to check STP until it clicked in my head what i was missing). Basically I was letting my cisco switch do all my VLAN tagging and then two 10 GIG SFPs connect to the core switch via a trunk. Once I did the add VLAN "number here" for STP everything worked.

You do not need STP for a VLAN to work. Nothing showed up in the output of that command until you added it to an interface because that is when the STP instance is created.

Stupid question, are you relying on GVRP or something to dynamically create the VLANs in your Huawei switches or did you statically configure the VLANs on your user switches?

Don't you have to set "switchport mode trunk" on the actual interface instead of the ether-channel?
