Cisco trunk and multiple vlans
hello,
i have 2 SSID defined in EAP225 and setup as VLAN 1 and VLAN 14.
on the Cisco switch i have this settings:
interface GigabitEthernet0/4
description TP-Link EAP225
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,14,100
switchport mode trunk
spanning-tree portfast
end
But is not working, if i setup the Cisco port with access and access to a single VLAN, any VLAN is working, but in any configuration is not working.
I have also contacted the TP-Link Romania (great support, hello to the guy on the other end of the phone) but no solution yet, using TP-Link products is working, but EAP225 + Cisco and trunking is a no go.
Any idea what i am doing wrong?

ok, yes, I don't quite know where it stops, I've done some tests here now, it's not a cisco switch but an access point direct in the router.
created a managed vlan 100, and vlan 1 and 14. everything worked right away. I also have cisco switch at customers with config that I sent earlier, it also works fine. but there is probably a small missconfigurtion somewhere.
but you probably cannot use trunk only against these access points, I think you must have a native vlan configured on the port. (an untagged port)
I don't think I can help you much more, you'll probably have to escalate this to support.
it would be nice if you could update us when you find a solution

@MR.S the problem somehow is escalded from Romania support,
But what i have undestand is necessary to have tagged and untagged traffic in the same time, and is not possibile in cisco using the same port,
in cisco untagged == access port, tagged == trunk. Is impossibile to have both in the same time.

@MR.S is added already and ignored, because the default is vlan 1. any other vlan is accepted because is not default. but adding switchport access vlan 1 will be ignored because already is 1

Ok,what happen when you add this
switchport trunk native vlan 1
this do a trunk port native. if you connect a computer it should get ip from vlan1

The trunk configuration looks fine, but I’m not sure how you have configured the AP.
What’s the IP address of the AP? Is it from the subnet of VLAN 1 or VLAN 100? If your native VLAN is 100, use an IP address from its subnet. Of course, the AP needs to be also set up to send tagged traffic in all VLANs, except for the native one.

thanks for jumping in here :-) yes you might be on to something. now it is almost impossible to misconfigure these apps, but everything is possible.
can you send us a screenshot of how you have set up vlan on your ssid.
i have done some tests here and this setup works perfectly fine, management vlan is 100

@MR.S here are the screenshots
the UI is easy to setup, the problem is how the eap225 worki with trunks and what is the reason that is not working with recular cisco switches.
each VLAN has a subnetwork
VLAN 14 - 10.10.14.0/24
VLAN 1 - 192.168.1.0/24
VLAN 100 - 10.10.100.0/24

@MR.S done
is not working, still only the management is working
the DHCP server has traffic only from VLAN100
and the cisco switch has: switchport trunk allowed vlan 1,14,100
my concusion is that management is working with tagged traffic and the vlan 1 and 14 from the AP perspectiv is with untagged traffic.
but is imposibile to have tagged and untagged trafic from cisco
