Hi all,
Today I have a setup in our factory floor, with a stack of 2 X440-G2 switches in the distribution room, and ISW-series switches in on the production floor, like the setup below:
For added redundancy I would like to add another stack similar to the one I have, and then connect “from the other side” to the ISW line:
I’m a bit in the dark regarding MLAG, since it would basically work if I had a single ISW connected to a port in each stack. Will it work when I have two ISW’s, or will this be a typical ring configuration? Would it be possible to setup ring on the ISW ports, and use MLAG between the stacks?
Any other ideas?
Thank you, ISW do not support MLAG at all I believe. I’ve updated a picture below, same topology but I’ve inserted some text. Should I use ERPS ring-protocol “all around” like the picture? Or are there other/better alternatives? Will a full ERPS-ring have any disadvantages?
I’m open for other suggestions/topologies as long as I have redundancy from the central distribution room (I need two stacks). One solution could be to cable each ISW switch separately (using one cable from ISW1 into Stack1 and a cable from ISW1 into Stack2) - see picture below, however we have quite long distances so cabling will be quite expensive. But if this would be a “much greater” solution I will consider this too. I’ve made a picture below, but as mentioned this will trigger a lot of extra cabling for us.
