Spent the last few days debugging network issues at work.
Exhausting. You never get a full picture. You poke a little here, poke a little there, … Form a hypothesis and test it. Eventually, maybe, you can narrow it down a bit to some segment or even some component.
A very time consuming process. Even more so if you try not to cause downtimes for your users.
I want a magical device that allows me to look inside a cable/fibre.
But hey, at least we got rid of a bunch of Cisco switches in the process. So there’s that.
had a similar problem many years ago. some lovely individual decided to create a bunch of trunk ports which had no primary vlid they had also created multiple isolated vlans with no routing between subnets.
im convinced cisco was created by sadist
@email@example.com with layer8 being the super glue.
@firstname.lastname@example.org smart move from
cisco -> mikrotik they pack more bang for the buck and off a less-esoteric configuration system than cisco. the cost of course is a nice outcome. before i became involved with opnsense project i spent many years in mikrotik world. i quite enjoyed it.
cisco is mostly trash these days as their focus is a lot of consumer-grade gear which really is not amazing. they tried to do the whole cloud/sdn thing with meraki but it (much like ubiquiti) is firmware hell and full of exploits that take forever to get patched.
if your group cycles through more gear i’d suggest juniper. and yes, they can be affordable.
@email@example.com i understand that completely. mikrotik will carry you far. when you surpass it’s abilities i think that’s a good problem to have.
