Set your terminal speed to 1200 baud. That should give you access to the console port and allow you to set the config-registry back to the default value.

Are these Cisco Catalyst switches? If so, most IOS-based Catalyst switches have what's called the Cluster Management Suite (CMS) software installed. (Can also be downloaded from cisco.com if you have a CCO account) The CMS is a web-based switch management software that only requires a web...
It coulld be a virtual mac-address. This is typically used when some form of ethernet redundancy exists (ie. Cisco's HSRP or possibly by one of the servers with multiple ethernet connection to the same switch but is not running etherchannel)... teaming, perhaps?

When you say "connect", are you refering to users plugging into the 10/100 ports, or the vty ports (telnet)?
With the latter, you can issue the command "who" to find out the name and/or IP address of the user that's currently logged on the same switch.

Hmm.. I haven't done this myself.
Try:
access-list 101 permit icmp any any traceroute

Breadmaster,
Go to http://securecomputing.stanford.edu/alerts/cisco-update-17jul2003.html for the more "english" explanation of the vulnerability.
As the advisory mentioned, you either have to upgrade to the 12.3 version of the IOS or apply a few inbound ACLs (access control lists)...
As long as they have the same speed (ie. fastethernet or gigabit-ethernet), you can configure both switches to use fast-etherchannel (or gigabit-etherchannel) on the two fiber ports.

The "File has bad file magic number" error is the hint. You either have a bad, incomplete, or the wrong IOS image installed.
What I've noticed is that, IOS images for Catalyst 4000/4500 series SWITCHES always begins with "cat4000-...".
Your switch is trying to load...
You can use the set AS-Path prepend <as-path#> <as-path#> on your neighborship with the slower ISP. This would trick the slower ISP's router into thinking that the path to your network is longer via the slow link. Eventually, the routes learned from the faster link would be prefered.

VLANs are typically used to divide broadcast domains. We all know that broadcasts are part of the ethernet and TCP/IP standards and is used for ARP and DHCP, to name a few. Imagine having 200 or so users sharing a single broadcast domain (single VLAN), each broadcasting every few seconds. Even a...
No problem. However, just to clarify things, I meant to say E1 (2Mbits/s) instead of T1 in my original post.

You might have set the clock rate on the DCE router too low. Set it to a higher rate as the 2507's serial ports theoretically supports T1 speeds (2Mbits/s).

You can try using the command ip ospf network point-to-multipoint on the ethernet interfaces. This will give you the results you want without having to resort to BGP.
Just remember that one of the conditions for two routers to form neighborship using OSPF is that they must have the same OSPF...
I may be mistaken but, as I understand it, there could be an STP issue here. As you've bridged both ethernet interfaces on the router (and eventually enabled STP), this would appear to the outside world as a swith. And the fact that you've connected another switch (2950) in parallel, you'd...
I'm not sure if it can be done. However, it seems to me that relaying the bootp request into broadcast isn't such a good idea.
You can however, configure multiple ip helper-addresses on each VLAN (except the VLAN on which the DHCP servers reside) for every DHCP server you have.
Ex.

Hi Chris,
Try these steps:
1. Turn off the router.
2.Set your terminal (hyperterminal) to the lowest baud setting (150 or 300 baud). Click the connect button.
3. Turn on the router.
4. If you see garbage on the screen, click the disconnect button and swith to the next higher baud on...
My apologies. I was indeed refering to adding the command on the L-3 switches. I unconsciously used the term "router" instead, as an L-3 switch is functionally equivalent to a router.
Bob is correct in saying that these commands must be configured on every VLAN on the L-3 switch...
You should put an ip helper-address command on every VLAN on your L-3 switches pointing to your DHCP server.
Also, it would help if you include the command ip forward-protocol udp bootpc. This will only allow DHCP requests to be forwarded by the router to the DHCP server. Otherwise, any...
