Misc
- We have standards now! Please do not add hodgepodge stuff to our network infrastructure. Please see parts list below.
- There are two subnets, 10.0.0.0/23 for wired clients and 10.0.2.0/24 for wireless. The DHCP pool takes exactly 10.0.1.0/24
- What this means in laymans terms:
- Any IP that starts with 10.0.0 is a static IP
- Any IP that starts with 10.0.1 is a dynamic wired IP
- Any IP that starts with 10.0.2 is a dynamic wireless client
- The wireless access point comes directly off the pfSense box and does not pass through the switches in the rack. This just eliminates a few points of failure.
Internet IPs
- 216.135.94.120/29 (LVL1 IPs)
- 216.135.94.121 (bluegrass.net gateway)
- 216.135.64.2 (bluegrass.net DNS 1)
- 216.135.64.3 (bluegrass.net DNS 2)
Parts
- 2 Port Surface Mount Box
- Patch Panel for rack
- RJ-45 Jack (used in boxes and patch panel)
- Cable
- Patch Cable
Router Details
- Our router is a small pfSense box on the shelf in the network rack.
- It has five interfaces. We only use:
- WAN - connects to POE injector by TARDIS
- LAN - connects to Master switch
- WIRELESS - connects to wireless access point
- (These are labeled on the back on of the router in permanent marker.)
- DHCP runs here.
Switch Details
- Everything is layer 2, the switches have an IP address only for management purposes.
- Everything stays on default vlan.
- Master is a 24 port gig switch. All other switches have 24 100MB/s ports and two gig ports.
- For each access switch (A, B, C) the gig ports are trunked to provide redundancy and increase bandwidth.
conf t trunk 25 trk1 trunk trunk 26 trk1 trunk
- On the master switch three different trunks are created (trk1-trk3) to support the three access switches.
- If none of that made any sense, please just remember this: The links between switches have special configurations. Please do not move those cables around.
- Spanning tree is enabled (with portfast) and bpdu guard. If you create a loop the ports will get disabled. Telnet into the appropriate switch to re-enable it. All ports are labeled.
- For example: A7 = port 7 on switch A. If it is disabled:
telnet switch-a.lvl1.lan conf t int 7 enable
