Network information

synopsis

I've (xopr) created this network information page mainly because no-one knows the current setup by heart, and I'm preparing for Congress everywhere without breaking people's precious downloads..

current setup

trunks

1. router and 'main switch'
2. router and VoIP setup
3. 'main switch' and 'media switch'
4. 'main switch' and «unknown»2
5. 'main switch' and stackspace (not connected)
6. 'main switch' and entrance/webcam (not connected)
7. 'main switch' and 3D printcorner (not connected)

special settings

• Netgear router (DD-WRT), providing internet and wifi (spacenet, spacenet_5GHz, ACKspaceWifi)

has extra firewall rules (to prevent Wifi, VoIP and internet access from crumbling down on multicast streams)

insmod ebtables

insmod ebtable_filter

insmod ebt_pkttype

ebtables -F INPUT

ebtables -F FORWARD

ebtables -F OUTPUT

ebtables -A INPUT --pkttype-type multicast -j DROP

ebtables -A FORWARD --pkttype-type multicast -j DROP

ebtables -A OUTPUT --pkttype-type multicast -j DROP

notes

• All important connections have been labeled (trunks on both sides). Please keep the label on (and updated) at all times. You can find the label-tywraps in the network-connector box in the stackspace
• Multicast traffic cannot be filtered (IGMP snooping) by the Dell switches. The router filters them all; if you don't want multicast traffic, connect to the router for now.

todo

• create VLANs, do some descent trunking, provide 'standardized' ports for management, non-multicast, VM, VoIP and regular use.
