I probably should have checked this before I bought this device but oh well.
I have a CRS305 running RouterOS v6.44.6.
I have a direct attach cable running to my main router at 10 gigabit. While testing, I have a second 10 gigabit cable connected to another machine and the CRS305.
Is it possible to treat the Ethernet port as completely separate? It seems like it’s bridged into the rest at the moment. What I would like to do is have 1x 10G “uplink” to my router, then 3x 2.5G to machines. Is this possible? If so, how? Eventually I don’t want to have the Ethernet connected at all (or connected out of the way somewhere for config use only - can I expose the config UI on any other interfaces?)
Coming from Unifi and OpenWRT this learning curve is steep.
All the ports are ethernet, just with different communication standards.
Yes, you can remove any port from the bridge and assign an IP address to it. If you only require access from the one port you could move the existing IP address from the bridge to the single port. As you can easily cut yourself off by moving/removing IP addresses making use of MAC access in Winbox (this permits communication with a Mikrotik via a layer2 connection without any IP address on the Mikrotik) and/or “safe mode” is recommended. Alternatively as it is possible to add VLANs you could make the config UI accessible via a management VLAN on some/all of the interfaces.
Beware if you move the uplink interface off common bridge, then traffic passing uplink interface will be routed traffic (with all implications about IP addressing) … and routing is something CRS305 is not good at (yet). Currently routing speed is up to some 0.5 Gbps (but should vastly improve in ROSv7 with no ETA).
If only the speed difference (10 Gbps VS 2.5 Gbps) bothers you: the switch should be able to handle it without any special configuration.
