Very confusing RG260GS vlan setup

Hello,

I’am having problems configuring VLANs on RB260gs, here is what I want:

Port 5 - a trunk port to a cisco 6500 with VID 2,200,300
Port 4 - a access port to client ( untag VID 200 )
Port 3 - a access port to client ( untag VID 300 )
VID 2 is the management vlan.

I think i tried all the possible combination on the VLAN and VLANs tabs but with no succes..

How i think it should be done:

On VLAN tab:

  • port 5 - vlan enabled

  • port 5 - accept only tagged

  • port 5 - leave as is

  • port 4 - vlan enabled

  • port 4 - accept only untagged

  • port 4 - leave as is

  • port 3 - vlan enabled

  • port 3 - accept only untagged

  • port 3 - leave as is

On VLANs tab:

VID 2:

  • not member on 1-4 ( since is the management vlan ), on port 5 add if missing.

VID 200:

  • not member on 1-3 ( not used ports, or used for other vlan ), on port 4 always strip and on port 5 add if missing.

VID 300:

  • not member on 1-2,4 – on port 3 always strip and on port 5 add if missing.

It doesn’t work how I described above, how should this be done ?

On the system tab, in order to make vlan 2 the management vlan, should I uncheck the ports or just enter vid 2 below ?

I managed to solve the vlan problem but now i’am stuck at the management vlan …

It is posible to assign the management ip address to VID 200 for example ?
Till now on host table i can see the CPU mac only on VLAN 1 and do not respond from any other vlan no mather how i would try to achive that.

I also tried to make port 3 an access port to vid 200 ( untagged ), plugged a host to it and try to ping the rb260gs but with no success. I need to mention that vid 200 is correctly configured since i can ping other devices on that vlan from the host connected to port 3.

Read this carefully: http://wiki.mikrotik.com/wiki/SwOS/Router-On-A-Stick

Note that the switch will respond to http requests to its IP address on all ports. This behavior is a bit different than Cisco IOS that responds to untagged traffic via an IP bound to Vlan 1.

NOTE: Once you set port 1 to “trunk” mode, you will not longer be able to communicate with the switch unless you create a Vlan1 on your router.

NOTE: You must also create Vlan1 but it is not necessary to assign it to any ports, just create it.

NOTE: The management IP for the switch is handled a bit differently. You must create a Vlan1 with ID=1 on the physical interface that will trunk to the switch. Then bind your management IP to that Vlan1 interface.

Hello,

The reason i have a special vlan for management is because I want to isolate this traffic as much as possible. The actual topology do not allow me using VID 1 for management.

I think there is no way to move management to VID 2 for example or make the switch answer requests coming from VID 2, is that correct ?

We are looking into this problem - RB260GS itself cannot be accessed from any VLAN.
With fixes in new firmware Management VLAN should work by setting “Allow From VLAN” = 2.

After doing some research into this problem i discovered:

  • on rb260 i configured the uplink port to accept only tagged frames.
  • switch accept connections coming from VID 2 but it answer them on vid 1 ( guess ) untagged.
  • in order to make the mangement work ( a workaround ) I tagged VID 2 on the cisco device and put the port native vlan 2 in order to send the frames tagged on vid 2 and receive them also on vid 2.

cisco port config:

description to-mikrotik
switchport mode trunk
switchport trunk allowed vlan 2,200
switchport trunk native vlan 2
end

the problem with this setup is that i cannot forward vid 2 to other devices connected to mikrotik ( i will double tag this ), so i’am forced to create a separate vid that will be used only for rb260gs management and will always end to it.


@becs - when this firmware will be released ? now i’am running 1.8

Any update on this ? I still a major issue to not be able to change the management vlan.

Thanks !
