Cisco 867VAE-W-K-K9 multiple VLAN trunk

[Benjamin Tincey]

Hi,

I have a 867VAE-W and a Cisco AIRONET 1600 series access point.

I am trying to setup 5 vlans on the 867 and then a trunk port to the Aironet accesspoint.

I am familiar with setting this up but only using a configuration with subinterfaces on one of the routers port. This router doesn't appear to be able to create sub-interfaces.

Is there any way to achieve this or do i need to put a layer-3 switch between the 2 devices?

Hi Benjamin,

Assuming your connecting the Aironet AP to one of the lan interfaces then what I would suggest you do is create the vlans on the 867, Then setup SVI's for each vlan and let these deal with your layer 3.

So example would be

conf terminal 

vlan 10 

Name test1 

vlan 11

Name test1 

vlan 12 

Name test1 

interface vlan 10

ip address 192.168.10.1 255.255.255.0

no shutdown 

interface vlan 11

ip address 192.168.11.1 255.255.255.0

no shutdown 

interface vlan 12

ip address 192.168.12.1 255.255.255.0

no shutdown 

interface Fa0

description Connection to Aironet

switchport trunk encap dot1q (This command may not be needed)

switchport mode trunk 

switchport allowed vlan 1,10,11,12

I hope this example helps.

You will need to setup the aironet AP interface as a trunk and add a vlan for management or use vlan 1 if you are that way inclined.

Your router may have a limit on the number  of vlans some have a limit of 4 or 8 including vlan 1
