This documents details of how the core switching infrastructure is built, in case it needs to be redone in the future.
Some random notes on the core switch build and configuration...
- two for redundant operation
- a third as a cold spare
- higher-capacity power supplies
- heatsinks and thermal adhesive for switch chips
with modern Iceweasel/Firefox use Web Developer -> Get More Tools and install the Web Developer Extension, then after restarting use Web Developer Extension -> Miscellaneous -> Clear Private Data -> Clear HTTP Authentication to clear HTTP Basic Auth credentials after changing DD-WRT management passwords (otherwise any attempts to Save/Apply changes just go to a failure error or blank page)
First perform these steps on each device 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)
- set your machine's wired network interface to a static address of 192.168.1.2/255.255.255.252
connect to the management WebUI through any LAN port (initial login is a username of root with the password 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)
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
After sobering up, set these basic configuration options which deviate from the factory default configuration settings, as organized in the DD-WRT !WebUI!...
