Some random notes on the core switch build and configuration...

Firmware Installation

First perform these steps on each devicve to get the hardware up on the current DD-WRT firmware with desired features...

perform a 30/30/30 hard reset to make sure it's at factory defaults (note this is using the recessed red reset button, not the protruding blue one for WDS)
connect as 192.168.1.2/30 to its WebUI through any LAN port (initial login is root/admin)
upgrade the flash with a trailed E4200 mini build like dd-wrt.v24-18777_NEWD-2_K2.6_mini-e4200.bin (the Cisco/Linksys firmware updater looks for special headers, so this is the first in a two-stage load)
wait five minutes to make sure everything's booted and written to NVRAM (now is a good time to grab a beer)
perform another 30/30/30 to make sure any configuration artifacts are reset to the defaults for this build
confirm the DD-WRT password reset page is displayed
set root/admin as the new login (yes, I know that's the same as the old login)
backup the CFE as routername_cfe.bin (it embeds the original interface MAC so you want one archived for each device) and stash it somewhere for long term safekeeping, see here for details)
upgrade flash with a more featureful NV60K build like dd-wrt.v24-20453_NEWD-2_K2.6_std_usb_nas-nv60k.bin (this adds IPv6 and SNMP support, which we'll want)
wait an additional five minutes (and grab another beer if you like)
perform yet another 30/30/30
wait five more minutes (another beer... why not?)
confirm password reset page is displayed and Firmware: DD-WRT v24-sp2 (12/31/12) std-usb-nas shows in the top-right corner
set root/admin as the new login (we'll change it to something safe last thing)
celebrate with beer

Initial Configuration
