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

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.
