CRS - Trunk-Port with all VLANs including those, which are not configured?

RouterOS General

Hi!

I want to replace some switches with CRS-switches.

Is there any possibility to setup “trunk-ports” wich always hold all VLANs and

  • where every new vlan is instantly available tagged
  • where every unknown vlan is forwarded to, that enters another trunk-port?

Dell switches e.g. handle VLANs on ports this way, if they are configured with:
switchport mode trunk

Thank you for your help

You can do it like this (example is for ether1, but any ether / sfp / sfpplus ports can be set up the same way):

/interface bridge port
add bridge=bridge interface=ether1 frame-types=admit-only-vlan-tagged ingress-filtering=yes # this makes a trunk port - tagged only
/interface bridge vlan
add bridge=bridge tagged=ether1 vlan-ids=1-4094   # this makes this port pass all possible VLAN IDs
