Network

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.
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

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.

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.
