When I posted the following picture on twitter, it generated some chatter.
This picture was taken in the Computer Science Networking Lab. Two things about the lab from my prospective:
- I give them a single feed to the rest of the network, one vlan and a small dhcp scope in which to make things easy on them (There is more address space for them to use outside the scope, use at their own risk)
- Any problems I have in which the rest of my network is threatened, shutdown their feed.
Now back to the photo, is STP in play, is there a loop?
No loop! except in the cable. Each jack in this case represents a different rack, so the wall plates are "stations" to work at. This keeps the younglings from stacking onto of each other doing labs.
This is the way they chose to bring production network to the other side of the room to the lab rack. This was done by our Cyber-Defense team, last year's team can be found here.
No worries on this one but it is right inside the door and makes me double-take every time I see it.
Thanks to all that responded to the post on twitter.
