Ok guys, I think I might have something setup wrong here…
I have two Cisco SG300 series switches that have 4 vlans shared between them, and a mikrotik RB493G. I have replicated these vlans into my mikrotik and created a bridge for them. For the two ports where the cisco switches plug in I have the vlans created and those vlans are added to a bridge for each vlan.
looks something like this on the mikrotik:
bridge-trusted (eth2-trusted, eth3-trusted)
bridge-guest (eth2-guest, eth3-guest)
bridge-security (eth2-security, eth3-security, eth4, eth5)
bridge-infrastructure (eth3-infrastructure, eth6)
eth2 (office-switch)
eth2-trusted
eth2-security
eth2-guest
eth3 (was master-switch)
eth3-trusted
eth3-guest
eth3-security
eth3-infrastructure
eth4-6 just plain clients
The problem I am finding is that I don’t get anywhere near line speed on communication within the same vlans if it has to go through the microtik (for example: eth2-trusted to eth3-trusted). Recently my mikrotik has started to crash if I am transferring large amounts of data between the two also. I have worked around this by connecting the switches and then only one of the switches to the microtik, but I don’t like this approach as it doesn’t scale as I add more switches.
I am fairly sure that I need to use the master port setting, but I can’t figure out how to use the master port, vlan tagging and ensure everything makes it to the correct bridge.
I have tried to read the docs and that is how I made it this far, and have been running this setup for a couple months no problem. It was only last week when I moved the second switch to the mikrotik from the first switch that the problems started. Port space is starting to get tight which was the reason for the move.
If you guys need any more information let me know. I have no problem completely re-working my mikrotik setup if I need to, I just need to know how this should work so that I can get better than 25% line speed transfers when going through the mikrotik.
