Hi guys,
Is it possible to have multiple active VLAN interfaces on my 1801? I think I must be missing something here so if someone could point this out that would be great but I have int vlan1, int vlan 10 and in vlan 20 (default, wired and wireless respectively) At the moment everything is on VLAN 1 but I'm looking to move wired clients onto VLAN 10 and wireless onto VLAN 20 but at the moment I cant ping my VLAN interfaces so i dont want to move any clients.
Am I missing something? The integrated switch on this confuses me!
Cheers all
Tom

Hello Tom,
it is possible.
Just create the L2 Vlan objects before:
conf t
vlan 10
name wired
vlan 20
name wireless
then you associate switchports to the vlans as needed
int f1/5
switchport
switchport mode access
switchport access vlan 10
ports that you don't configure are in vlan1
Hope to help

Hello Tom,
you need to explictly unshut the SVI interfaces
int vlan 10
no shut
int vlan 20
no shut

Your config would look something like this:
int f0/0
no ip address
int fa0/0.1
encapsulation dot1q 1 native
ip address 192.168.1.1 255.255.255.0
int fa0/0.10
encapsulation dot1q 10
ip address 192.168.10.1 255.255.255.0
int fa0/0.20
encaps dot1q 20
ip address 192.168.20.1 255.255.255.0
If you have a switch, you'll need to add the ports that you want as access ports, and then you'll trunk the port that leads to your router.
For instance, if port 1 connects to the router and port 2 is on vlan 10, and port 3 is on vlan 20:
int fa0/1
switchport mode trunk
switch trunk allowed add vlan 1 , 10 , 20
int fa0/2
switch mode access
switc access vlan 10
int fa0/3
switch mode access
switch access vlan 20
The syntax may not be right, but that should work. :-)

Hi Guys,
Thanks for the advise above. I have put this in and that is all fine. Is it correct that I cannot ping the vlan interface? I created the interface vlan 10 and 20.
At the moment it seems to be acting just like a switch, is that correct?
Thanks,
Tom
