My network have a lot of vlan, almoust about 1000 vlan id,,from 1 to 1000,
I am using Trunk Port of my switch, i define the port can passthough 1-1500 vlan id.
Now i settting the RouterOS,,, I need add 1000 vlan interface for each vlan id, it make me crazy:-(
Can i setup an port as trunk port in routeros? same as the switch, let vlan-id range passthough the port?


Any help is very helpfull, thank you~!

i dont think so.. as far as i know you need to create 1500 vlan interfaces each one with one vlan id. i made a simple script that can help you save a some time creating these vlans.


:for i from=1 to=1500 do={/interface vlan add interface=lan vlan-id=$i}

this script will create 1500 vlans for you in a couple seconds.

Yes, till now, i only can do just like this:-(

Very thanks to gustkiller

you didn't say what do you want to achieve on ROS =)

i want to support more than 500 vlans, so i want to setup the port as 'Trunk' port as L3 switchs, i will more easy to use.

so you just want to bridge the traffic and not dig into the vlans ? you can use a bridge and setup the mtu to 1504 and i think that will work.

I have over 500 vlans, and trunk to RouterOS to access internet, so i need setup more than 500 vlans to support these vlans.
Infact i am using an bridge to bridge these vlans, and drop the forwared packet between these vlans, then setup gateway address and dhcp-server and hotspot services on the bridge.

when the vlan is just about 100, it works fine, but i found if i setup more than 100 vlans, the routeros become unstable, system become strange, sometime can't resolve the dns, sometime can't ping the gateway address on the bridge, sometime can't web, i become crazy now , i hate this case.

Is there some more tips to solve this problem? very thanks to u ~!

I still don't exacly understand why you want a vlan per room. You will be able to see from the hotspot username what rooms are logged in. If you see user james.johnson is logged on and know in which room he stays its easy to identify the room?

my guess is he is trying to separate all users for security. I think the best setup would be one router for all vlans, and then a second router that is the internet access / hotspot gateway. This way you don't have to run the hotspot on the bridge (which is still not working for me either). Just my opinion.

As you know , the hotel dont't want charge the network free, so they don't want to let guest enter username and password. so the last way is using vlan to identify the room

Yes, i am trying this today, but could you kindly give me more detail about the configuration about the router for all vlans?
Maybe i need using bridge to bridge over 500 vlans (on ether port A) and another fix ether port B and then connect port B to the another router witch run the hotspot ?

very thanks to changeip,,,,
