I believe that we have been doing traffic shapping for Bay's Centillion over OC3 interface for a while. Our Yurie switch can shape to satisfy all normal public ATM network requirement. The Yurie switch is also used in the Splitrock network and you can get service from them without shapping your output. Their Yurie switch will provide all buffering and necessary shapping.

cflowd - works?
by Leigh Porter 24 Apr '98

24 Apr '98

Hiya, Thanks to the folks who posted the cflowd data, and to the anonymous scripter :) After getting cflowd to compile on a Linux box, it starts fine and two processes appear, bound to UDP port 2055 - seems OK. Some files are created in /var/tmp (I left the default on for now!) and all seems OK. But no data is collected.. I assume all that is required on the router is: ip flow-export 10.45.16.92 2055 An strace ran on the cflowd process shows it just waiting for select calls to timeout on both processes. Looks like the router is not sending anything out, it's running 11.2(9)P on a 7507 with 96Mb memory. Does the Cisco require any special software for this? Regards, -- Leigh Porter

Perhaps he was mis-spoken... I got ahold of someone internal to Cisco who faxed me a bit more information (summarized below:) similar to the PA-H supports speeds up to 45Mbps requires IOS 11.3.(3)T or later supported on 3620 and 3640 support for 2600 "not planned" So..either the document I received was in error, or all the "heads" aren't talking.

What happened to the access-list blahblah established command in 11.1.15? is it missing? I find some stuff about reflexive lists in 11.3 which would be nice but it disappear from 10.x to 11.1, the machine even claims I should be able to use an established parameter but doesn't offer it to me. sigh. jlw -- Jason Weisberger Chief Technology Officer SoftAware, Inc. - 310/305-0275 "Let us cross over the river, and rest under the shade of the trees." -Thomas Jonathan "Stonewall" Jackson

an apology re: Quoting and threading ..
by Joe Rhett 22 Apr '98

22 Apr '98

I was overly concise in my response, and a number of people have written to correct me on this. So I'm writing to apologize, and clarify what I meant here. Someone: >>> That's a feature, not a bug. It allows people to read things in >>> context. Not a problem from my perspective as long as the quoted >>> material is at the bottom of the message. Me: >> NO, see, my e-mail package has this "feature". It lets me read mail in >> threads. I don't need people to help it out. Owen (and others with similar messages): > Well, Joe, you're not everyone, and the quotations by many of the > people are of great help to some of us, me included. I have no problem with relevant and concise quotes that help us understand the issue being addressed. My response was aimed at someone who felt that the entire thread should be preserved in each and every message -- this is completely unnecessary! If someone wants to read the entire thread, they should use a threaded mail reader. The messages themselves should contain only enough quoted information to assist in understanding the response. -- Joe Rhett Systems Engineer JRhett(a)ISite.Net ISite Services PGP keys and contact information: http://www.navigist.com/Staff/JRhett

AT&T Outage cause last week.
by Rodney Joffe 22 Apr '98

22 Apr '98

According to AT&T, in a story just released, the problem was a Cisco code problem. It would be interesting to hear what the actual software cause was, if anyone from Cisco cares to let us know?.../rlj - - - AT&T's network failure AT&T Corp. reported today that last week's frame relay network failure was due to a software-based problem. Last Monday's network failure disrupted service nationally for thousands of AT&T's business customers for about a day. The cause of the outage was previously attributed to the interaction between two frame-relay switches, but AT&T now says it was a software problem. AT&T Chairman C. Michael Armstrong said today the company is working closely with Cisco Systems, which provided its switches, on ways to fix the problem. The type of network application affected by frame-relay service is "any kind of high-speed data applications where large amounts of information [are] exchanged in quick bursts," Granieri said. Querying an inventory database is one example of such an application, he said. Reuters contributed to this report
