Why would I use an EX4200 as an L2 switch?

LACP allows you to run network traffic over multiple interfaces between a single source and multiple destinations.

This outlines the things I had to do on the backend to get sieve filtering working on Dovecot 2.x on FreeBSD.

Cisco and LACP

I have a FreeNAS machine which has 4 ethernet ports on it. I’d like to setup LACP so I can get more than 1 Gbit of traffic on/off the NAS. In order to do this, I need to make some changes to both my FreeNAS machine and my switch.

Quick note on what I had to lookup when I needed to reset a Dell MD3000i to factory defaults. This process assumes you have the proper cable already (it looks like a headphone jack on one end and an rs232 on the other).

IPv6 Privacy Extensions

https://cryptomonkeys.com/2013/02/privacy-extensions/ 2013-02-10

Many operating systems use the EUI-64 algorithm to generate IPv6 addresses. This algorithm derives the last 64 bits of the IPv6 address using the MAC address. Many see this as a privacy problem. The last half of your IP address will never change, and with MAC addresses being somewhat unique, the interface ID becomes close to a unique “cookie” identifying your system.
