Note: When an entry is created under /interface ethernet switch ingress-vlan-translation, then the switch chip will add a VLAN tag on ingress frames on the specified port. In this example VLAN99 will be used to access the device, a VLAN interface on the bridge must be created and an IP address must be assigned to it.Īdd interface=bridge1 name=MGMT vlan-id=99Īdd address=192.168.99.1/24 interface=MGMT Set drop-if-invalid-or-src-port-not-member-of-vlan-on-ports=ether2,ether3,ether4,ether5 interface ethernet switch egress-vlan-tagĪdd tagged-ports=ether2,switch1-cpu vlan-id=99Īfter valid VLAN99 configuration has been setup, you can enable unknown/invalid VLAN filtering, which will not allow the management access through different ports than specified in the VLAN table:
Packets that will be sent out from the CPU, for example, ping replies will not have a VLAN tag, to solve this you need to specify which ports should always send out packets with a VLAN tag for a specific VLAN ID:
For example, to allow only VLAN99 to access the device through ether2 you should first add an entry to the VLAN table, which will allow the selected port and the CPU port ( switch1-cpu) to forward the selected VLAN ID, therefore allowing management access: If you are intending to use invalid VLAN filtering (which you should), then ports, from which you are going to access the switch, must to be added to the VLAN table for untagged ( VLAN 0) traffic, for example, in case you want to access the switch from ether2:Īllowing only tagged traffic to have management access to the device through a specific port is a much better practice. If invalid VLAN filtering is not enabled, management access to the device using tagged or untagged ( VLAN 0) traffic is already allowed from any port, though this is not a good practice, this can cause security issues and can cause the device's CPU to be overloaded in certain situations (most commonly with broadcast type of traffic).

You should also assign an IP address to the bridge interface so the device is reachable using an IP address (the device is also reachable using a MAC address):Īdd address=192.168.88.1/24 interface=bridge1 In all types of management access it is assumed that ports must be switched together, use the following commands to switch together the required ports:Īdd bridge=bridge1 interface=ether2 hw=yesĪdd bridge=bridge1 interface=ether3 hw=yesĪdd bridge=bridge1 interface=ether4 hw=yesĪdd bridge=bridge1 interface=ether5 hw=yes In such cases you will need to configure management access.

It is possible to use device's serial port for management access, but in most cases such an access method is not desired and access using an IP address is more suitable. In general, switches are only supposed to forward packets by using the built-in switch chip, but not allow access to the device itself for security reasons. Prior to RouterOS v6.41 port switching was done using the master-port property, for more details check the Master-port page.
Note: Port switching in RouterOS v6.41 and newer is done using the bridge configuration.
