You might also be interested to know that there is a little-known bug in the 3600 platform that causes the router to boot to ROMMON mode if the router is power cycled several times in rapid succession. The example below uses Hyperterm to break into switch: mode on a 2955.

For more information, refer to Standard Break Key Sequence Combinations During Password Recovery. On a workstation running UNIX, Ctrl-C is the break key.

I've tried this on a 3600 in my lab & it works great. Hyperterm running on Windows 2000 uses Ctrl + Break.

Here's one method (taken from the same doc.): From here you can either recover the password, or if it's encrypted, change the configuration register so you can enter the intial setup dialog when you reboot. So, reboot the router & press cntr-break to enter ROMMON mode. My guess is you're either not waiting long enough (at least 5 seconds) or waiting too long before "breaking" the router.

"Break (system interrupt) is always enabled for 60 seconds after the router reboots, regardless of whether Break is configured on or off in the configuration register" Simplicity and cost are key.If you have read the link supplied by jeter, you will notice the line that says: One thing to keep in mind is that these customers are VERY small offices (2-8 PCs) and most, if not all, don't even have a dedicated server.

So my questions for the Cisco Catalyst 2950 (or others switches if you know a better one) with the Enterprise software are this:ġ) Can you set bandwitdh (both ingress and egress) per port? This is a must.Ģ) Can you use one port in multiple VLANs? I figured that each VLAN would include the firewall port and the customer port. By default, these switches will not respond to a console break signal the same way routers do. Another problem is that we would quickly run out of PCI slots, requiring a second firewall. The problem with this solution is that Linux traffic shaping is a hodgepodge at best, requiring kernel patches and plenty of upkeep. My original solution was to run each customer into a dedicated NIC in the Linux firewall and let Linux handle DHCP serving and bandwidth shaping. The problems here are twofold:ġ) All customers are on the same hub and IP network (.x), which is really badĢ) We want to implement bandwidth restrictions, because they will be paying for different speeds As it stands right now, it's CAT5 from their office to an isolated hub which goes into a Linux box doing DHCP and NAT to get them out on the internet via a second NIC. We are in a small office building and have a few tenants on our floor using our Internet connection. Token apology for the ignorance on this one, but I have never touched a managed switch in my life.
