Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Change default values on Foundry (Brocade) RX and MLX BigIron L3 (routers & switches)

The sample output, is a display of the values you can change, using this command. After a change of of these settings you will need to reload the box, by typing...wait...wait for IT: 'reload'. This comes in handy when working with the RX hardware, for example, which has a base limitation of 32 (RSTP (802-1w) instances. For all of you paying attention that means if you run RSTP on a RX you can only have 32 VLANs. Sure, you can have common groups of VLANs, like back in the day style MSTP, PVST, PVST+ (and all that old STP (802.1d) mess), before "per vlan spanning-tree", RSTP (802-1w), was made. But who wants to do all that?
