I have a bunch of loud noisy switches…cough Juniper EX4200s cough. I recently moved and haven’t had the time yet to setup proper sound proofing for all my homelab gear and thus I need to be quieter where I can be. Lower power consumption would help too.
Right now the switch has about 20 ports populated and is doing a fair amount of work. It’s pulling only 17 watts. My EX4200 pull about 135 watts; that’s a substantial difference. Based on my calculations, running an EX4200 24/7 would cost about $8.70/month in Ontario and the CRS326 about $1.50.
The switch also has no fans, so it’s virtually silent.
The challenging part of this switch is that Mikrotik has many different products, and they use many different CPUs and ASICs.
In their C3XX line you configure VLANs differently than their other switches, as they do hardware VLANS. They have some docs on configuration. These short docs are not detailed, but they are accurate in my experience.
Example 3 is probably the one most people would use…“VLAN Example #3 (InterVLAN Routing by Bridge)”:
/interface bridge add name=bridge1 vlan-filtering=yes /interface bridge port add bridge=bridge1 interface=ether6 pvid=200 add bridge=bridge1 interface=ether7 pvid=300 add bridge=bridge1 interface=ether8 pvid=400 /interface bridge vlan add bridge=bridge1 tagged=bridge1 untagged=ether6 vlan-ids=200 add bridge=bridge1 tagged=bridge1 untagged=ether7 vlan-ids=300 add bridge=bridge1 tagged=bridge1 untagged=ether8 vlan-ids=400 /interface vlan add interface=bridge1 name=VLAN200 vlan-id=200 add interface=bridge1 name=VLAN300 vlan-id=300 add interface=bridge1 name=VLAN400 vlan-id=400 /ip address add address=126.96.36.199/24 interface=VLAN200 add address=188.8.131.52/24 interface=VLAN300 add address=184.108.40.206/24 interface=VLAN400
A few notes:
/interface bridge portand
/interface bridge vlanwill be your friend
Also note that if you don’t have an “H” beside a port then it’s not being managed in hardware and will be slow.

For some reason I like Mikrotik gear. I have quite a bit of it, including some wireless (don’t get me started on the whole capsman thing). What I don’t like about Mikrotik is that the documentation is somewhat lacking. Configuring a Juniper switch can be done easily with some surface level googling as pretty much every Juniper question has been answered succinctly and search engine indexed. Not so with Mikrotik. Their large and changing product line, part of their value proposition, makes this even more difficult.
One thing I do like about Mikrotik is that the OS comes with many features, even MPLS. This system is not just a dumb switch, it is a full featured router.
Finally, the switch is only 24 ports. Technically I’d have to have two of them to match the 48 ports of the EX4200. When you have many boxes ports will run out quickly.
You can certainly find cheaper, older used switches, but they will likely be loud and power hungry.
