Highlights

Notes on the core switch build and configuration...

• Cisco/Linksys E4200 v1
• two for redundant operation
• a third as a cold spare
• higher-capacity power supplies
• heatsinks and thermal adhesive for switch chips
• DD-WRT standard

• custom switch driver to allow 802.1q VLAN tag remapping

• with modern iceweasel/firefox use Web Developer Extension -> Miscellaneous -> Clear Private Data -> Clear HTTP Authentication

Firmware Installation

Steps to get the hardware up on the current DD-WRT firmware with desired features...

1. perform 30/30/30 reset

2. connect as 192.168.1.2/30 to its WebUI through any LAN port

3. initial login is root/admin

6. perform 30/30/30 reset

7. confirm password reset page is displayed

8. set root/admin as the new login
9. backup the CFE as routername_cfe.bin (in embeds the original interface MAC) and stash it somewhere for safekeeping

10. upgrade flash with dd-wrt.v24-20453_NEWD-2_K2.6_std_usb_nas-nv60k.bin

11. wait an additional five minutes for good measure
