A real console on the Linksys SRW2024 switch?

I’ve been meaning to write a page on the configuration of a Linksys SRW2024 switch for quite some time, but just never got around to it. If you’ve read any of my other posts on this switch, you’ll find that I blast the user interface for configuring the device. The web interface only works in Internet Explorer, and the telnet/ssh/console configuration functions are completely useless.

That is however until I discovered a way to get to the REAL command line interface for the device. This CLI is pretty much a customised Cisco IOS when it comes to command set – and for those of us like me with Cisco experience, a doddle to master.

I’ve written up a complete page about it here for those who wish to unlock the awesomeness in the Linksys SRW2024.

    Wow, that’s really great news.

    I bought me this fine piece of hardware with some crappy configuration software on it about 2 years ago and wished the sucke^Wcoding monkey^W^Wdevelopers at Linksys every pest I could imagine.

    This brought me to the plan to hack this device, i.e. get some decent OS on it, with some sane CLI tools.

    Having a sane CLI now, reliefs the problem, though my plan to hack it isn’t dead yet. Now that I definitely know, that there’s running IOS on the thing I can do some recherce on it so that I can reverse it (mainly it’s finding out what all those commands are doing to the hardware). Unfortunately the SRW2024 has some hardware manufactured by Marvell in it.

    I really tried hard to get some tiny piece of documentation, but it seems you need some very strong Voodoo to get it, which I don’t have as it seems 😉 All my requests bounced with answers like: “If you’re not in development of new hardware and sign some NDA you don’t get it. And since we consider the piece of hardware you requested on as depreciated, i.e. not to be used in newly developed products we won’t give you any documentation on that thing anyway.”
    And in that case it was merely about the switch’s system CPU, which is some ARM9 core, with only some networking stuff integrated, so nothing to make some big corporate secret fuzz about.

    Oh, and if anyone familiar with the innards of Cisco IOS read this comment: Feel free to contact me at

    Steve, I just bought this switch and installed the latest 1.2.9 firmware. CNTRL-Z doesn’t seem to do anything at the menu prompt. Have you experienced the same thing? Any otherway to break into the command prompt?

    1. Hmmm – you will need to login with your username/password first – before pressing CTRL+Z.

      I’m using:

      SRW2024# show ver
      SW version 1.2.2b ( date 28-Feb-2008 time 16:47:37 )
      Boot version 1.0.1 ( date 11-Jun-2006 time 18:43:59 )
      HW version 00.03.00

    Yep, I’m logged in. Have menu showing etc. But CNTRL-Z does nothing. Maybe I’ll try downgrading to 1.2.2b to see if this is the case. Although 1.2.9 fixed many things, including web issues.

    Ok, I can’t find 1.2.2b ANYWHERE online, especially since Cisco changed the support page for Linksys – anyone able to send me in email if possible?

  1. Try this file. I think this is the right one – I found a copy on my TFTP server. Hopefully it should help you out.

    Thanks Steve, it worked. So looks like 1.2.9 killed the ability to get to the command prompt.

    Thanks again
