CAPsMAN - Problem through rename from virtual wireless interfaces

RouterOS Wireless Networking

Hi,

i have a problem with my wireless setup. I use CAPsMAN for my Wireless-APs. I would like to have a second SSID for the guests and therefore i created a virtuell interface on the CAP Interface. Then i go the AP and add the virtuell interface to the bridge of the AP and everything works fine. I use local forwarding on the APs. The interface gets the name wlan3. When i change something in the configuration in CAPsMAN the virtuell interface on the AP gets renamed to wlan4, then wlan5 and so on. Then i have a unknown device on my bridge and the guest wlan is broken. So everytime i change something in the configuration i have to delete all unknown interfaces on the bridge from the APs and add the knew ones. Any idea what i do wrong?

Any suggestions for settings to change that might fix this are very appreciated.

Capsman - difference between create enabled and create dynamic enabled.

Hi,
change action in radio provisioning from “create dynamic enabled” to “create enabled”. This way it will not change the interface name when you provision cap and you can also rename them to whatever you like.
(see https://wiki.mikrotik.com/wiki/Manual:CAPsMAN#Radio_Provisioning - dynamic in here means new name will be always generated)

Hi,

i created a provisioning-rule and the configuration was transmitted to the ap. When i change something in the configuration it renames the interface also.

Thank you for your reply.

The ap changes the name from wlan6 to wlan7.

Ok, i’ ve found the problem.

To overcome this it is possible to use the static-virtual setting on the CAP which will create Static Virtual Interfaces instead of Dynamic and allows the possibility to assign IP configuration to those interfaces. MAC address is used to remember each static-interface when applying the configuration from the CAPsMAN. If two or more static interfaces will have the same MAC address the configuration could be applied in random order.

To facilitate data forwarding configuration, CAP can be configured with bridge to which interfaces are automatically added as ports when interfaces are enabled by CAPsMAN. This can be done in /interface wireless cap menu.
