Hi, I’m installing a new CRS354-48G-4S+2Q+RM switch.
I have noticed from the test results (the results are from official product page) that the switch’s throughput depends a lot if its used in switching, bridging or routing mode. I tried to boot the switch to SwOS, so that only switching features would be available, but the switch went to boot loop. I needed to connect with serial cable to change the boot OS back to RouterOS. I realised afterwards CRS354 runs only with RouterOS as RouterOS is the only OS listed on the product page.
Now I’m wondering which features of RouterOS I can use, so that I don’t accidentally start using routing features which would slow down its performance.
All routing should be done by the firewall CCR1036-8G-2S+. Basically I need separate VLANs for couple servers, different WiFis and admin network.
Previously I’ve been only configuring L2 switches with VLAN capabilities, so I’m bit confused with the configurations. In the throughput results it’s stated that Bridging way slower than Switching, but it’s not clear to me what the bridging means in this context. Does this bridging include Bridge VLAN Filtering like in the wiki article below?
