Vlan question

Sorry guys for the stupid question but i want your guru help i have a mikrotik RB2011 and there was already a hotspot server on it
all ports are bridge

is it possible to add a vlan on the existing default bridge to pass it through some cisco switches so i can be able to keep hotspot ip range and put some other computers to the new vlan?

is it possible and how?

thanks in advanced

I’m a RouterOS noob, but I found the links in this post helpful when I was learning the RouterOS bridge way of dealing with vlans.

I found the Official documentation quite good, but I have used vlans on different platforms.

If you are expecting someone to be able to help you, you should read these two threads.

Yes you can…
However if you follow the advice on the second post and go with Bridge VLAN Filtering, you will loose the hardware offload on your Bridge since Atheros 8327 ( the switch chip on first 5 ports of RB2011 ) does not support Bridge VLAN filtering in Hardware…
However, it supports VLANs on the Switch chip it self ( only for Atheros 8327 and not for Atheros 8227 ports 6-10 )

Setup example here https://help.mikrotik.com/docs/display/ROS/Switch+Chip+Features#SwitchChipFeatures-VLANExample1(TrunkandAccessPorts)
Also the article suggested on second post is really good to read, although i do not suggest to program RB2011 that way ( if you don’t mind losing HW offload you can use Bridge VLAN filtering but performance will decrease )

beware of this

@chechito you are right, i just missed that Atheros 8227 has a VLAN table too, my mistake…
