Replacement for a Extreme Black Diamond 6808
by Drew Weaver 16 Mar '04

16 Mar '04

Can anyone suggest a good replacement for an Extreme Black Diamond 6808 switch, we use it for aggregation, however their support is abhorrant and every time we have an issue they require us to unconfigure the switch, reset it to defaults and manually reconfigure it, no matter what the problem is, the resolution is the same. Anyone have any suggestions? -Drew

Stateful Ethernet Bridging and it's effect on overall Internet topology.
by Gregory Taylor 16 Mar '04

16 Mar '04

I have a question and would like all of your opinions on this matter, as I research heavily into stateful ethernet bridging, packet mangling and their advantages and disadvantages to local and wide area network topologies. Deployed in large volumes, what negative effects, if any, would ethernet and fiber bridges have on the Internet as a whole. Lets say I was to build a bridge designed to intercept and manipulate traffic coming in from an outside network into my 'colo site' to do traffic shaping, packet filtering, and ethernet frames manipulation. And I deployed 100s of these into the facility as a means to control overall traffic. Would these transparent bridges be detrimental in any way to the rest of the internet. I understand that since they are re-transmitting data that the possibility of their MAC addresses popping up every time a machine behind it pops up could be an issue when doing network monitoring. But I'd just like to know what everyone thinks about such products. (Excuse me if my statements seem a little incoherent, I just woke up) Greg

BaneTele hosts an EFnet IRC server. Caused no significant problems while I was working at BaneTele. That's probably because we *expected* DoS attacks on the IRC server, and engineered the network accordingly. Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no

And, while not knowing the specifics of this situation, if you were being attacked, and it hurt your network, would you continue to piss the attacker off by validating it? You'll have a problem finding anyone that crazy, I think.

Re: 2001:590::/32 announced by both AS4436 (nLayer) and AS4474 (Global Village, no contact in whois, but seems to be nLayer...)

>[cc: to hostmaster(a)arin.net, maybe now it will get their >attention instead of going into /dev/null] This is an odd thing to do because you don't say what action you would like ARIN to take. What do you think ARIN should do? >ASHandle: AS4474 >Comment: The information for this ASN has been reported to >Comment: be invalid. ARIN has attempted to obtain updated data, but has >Comment: been unsuccessful. Clearly ARIN has already done something about AS4474. So what else do you think they should do? Note that you might want to take this type of discussion onto the ARIN Public Policy mailing list which is open to anyone whether they are an ARIN member or not. http://www.arin.net/mailing_lists/index.html#ppml --Michael Dillon

Because I am not watching IPv4 tables and cogent announced it. Also both those ASN's are properly registered in the registries.

I seem to be missing it. I am a user of the internet who asked for a answer at their NOC from which I got *no* reply, except for ticket numbers, even after sending 2 messages the last two weeks. Which then caused me to inquire NANOG which is a correct list to do so as nLayer is a US based (North American) "ISP". Next to that mentioning nLayer to abuse-tracking people seems to also get a response that there is quite a lot of abuse in the forms of spam from them. Is that the reason they are 'migrating' to hide their paths from the spam aware people? Maybe you, as a perfect customer, can ask them to update their objects in the ARIN registry or stop hijacking internet resources?
