Title: LAN Infrastructure Changes
Post by: BrotherTobious on July 23, 2015, 10:18:38 AM
LAN'ers of Dead Men, last LAN it is fair to say we had a fair few problems that really impacted our weekend.  

In the dark and damp backrooms of LAN admins HQ we and the Council have been working to make sure this doesn't happen again.  So some changes have been made and they are as follows



We hope that this might answer some of you questions in regards to this.

That's great news Toby, do you think the switches are in good enough shape to handle another LAN?

Worst case, a few of us can nick some old gear at work. There's bound to be some gigabit switches destined for replacement.

One step at a time and chances are the Admins might break before the switches do.

Great news and well done guys. :yahoo:

No idea if there are any danes attending this lan, if there were they could stop by my place and pickup some new cisco switches, which i wouldn't mind donating for the lan to keep.

Note switches have now been donated to the local youth clubs lan parties.

Yes.

The problems we experienced at the lan were not really down to the switches, more to the hotel's 'new' network setup.    

Our switches are all gigabit so have more than enough bandwidth to handle the small throughput that the lan generates.    Whilst we have found a few dead ports, as each switch has 24 ports we should not be lacking in connectivity options.   The lan switches are in the budget plan to be replaced next year unless we can find a valid reason to spend the money sooner.

Make sure they are config'd to run as 'dumb' switches please or all hell will probably break loose on the network if they are used!

Well, if a switch is malconfigured it is only likely to affect itself and downstream clients. Still, would be good if all ports are VLAN 1 :)
Not too familiar with HP's setup, but they probably have things like DHCP Snooping? That's really useful at a lan. If someone or something starts handing out DHCP responses where none is expected, you can filter it or shut the port completely. That way, only the authorized DHCP server gets to respond to requests. Cheap insurance against idiots :)

Just telnet or ssh to the thing and reset it to factory defaults. Might need a hardware factory reset if nobody knows the password. Then it's be in in a single vlan mode no L3 or any smart stuff we don't need. Bring a PDF of the manual along.

Can you give us the exact model number right off the back of the switch, full string of characters and serial number as well Sneaky?

I'm bringing 2xhp pro curve 2610-24 pwr and 2x1800-24g switched all 4 are vlan capable from what I've read.

Hi Sneaky, are you looking to sell them or something?  

We already have our own gigabit switches for the LAN at each table and won't be plugging in anything else as it potentially could cause conflicts and be a bit of a nightmare (especially the 2610 as it is not even gigabit).  As we will be in control of our own direct internet connection via a dedicated router to which we will have full admin access then we won't have need for any additional vlan capability other than what will be provided (if required) via router.

It's a very kind thought to bring them along, but if you're not planning sell them then you might want to save yourself a bit of space in the car!

This post and yours moved from the Seating Plan thread to the infrastructure thread.

No worries.  The problems at the last lan weren't the switches, so we should be fine thanks and this thread sets out why in the OP.  :thumbsup:
