RB2011L

The RB2011 is a low cost multi port device series. Designed for indoor use, and available in many different cases, with a multitude of options.

The RB2011L is the most basic model, with five Gigabit ethernet ports, five Fast ethernet ports, power jack and PoE support.

It’s powered by the new Atheros next generation 600MHz 74K MIPS network processor and has 64MB of RAM and a Level4 RouterOS license.

If you need low-cost Router with ten Ethernet ports for your OEM application, RB2011L is the way to go!

All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
Values in Italic indicate that max throughput was reached without maxing out CPU, but because board interface configuration was maxed out
Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
