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

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
