One Wilshire building / Downtown LA power failure?
by Eric Kuhnke 13 Jan '04

13 Jan '04

I am hearing reports of a power failure in downtown los angeles, particularly the One Wilshire building. One uncorroborated report says that the entire building just switched to generator power several minutes ago. Does anyone in 818 have more information?

Yes they did lose power. I have a presence there and I saw the hit on some of my equipment. Not directly on my equipment but 2 of my POS circuits went down. No word yet if they are still on Generator or not.

I'm amazed no one mentioned Etheral works just fine under Windows (well, at least it runs as well as any OTHER Windows software seems to, let's put it like that). I guess those of use lucky enough to use Linux/Unix/*BSD etc forget there are other, less fortunates out there :) You can install PCAP for Win32, as well as Ethereal for Win32.

While this sounds great on paper, our experience has us shying away from dCEF and looking for something bigger and better... dCEF pushed the RSP processor down to about 5%, but pushed up the VIP processors to about 90-95%... > VIP-Slot0>sh proc c > CPU utilization for five seconds: 13%/12%; one minute: 14%; five minutes: > 15% I wish we could get our routers to do this... > Obviously, we run dCEF, which puts the VIP's in the position of forwarding > everything on their own, as evidenced by the CPU measurements. But each VIP is responsible for it's own traffic, so if a particular VIP runs most of the traffic, it has much higher CPU usage... In our case, we have a router loaded with VIP 4-50's and Enhanced ATM OC-3 adapters... Originally, we had a single OC-3 running about 120-130 Megs constant and the VIP CPU was at 90-95%.... To combat this, we had to put in additional OC-3 cards with additional VIPs and distribute the load... Still, high CPU is a problem .. For instance : CPU utilization for five seconds: 63%/63%; one minute: 63%; five minutes: 65% 30 second input rate 78227000 bits/sec, 17858 packets/sec 30 second output rate 47944000 bits/sec, 12778 packets/sec It seems to me that we should be able to do sooo much better... *sigh* OC-12 adapters are an option, but they are rather expensive ... > However, to answer your question, even a modestly configured 7507 with > RSP4, and VIP2-50's will be substantially more capable than a 7206-NPE300. > Things may change on the NPE-400 or G1, but I have no direct experience > with that. The G1 processors, so far, have proven to be wonderful... We only have experience with them running in the 7200 uBR chassis, but they've shown a huge reduction in CPU utilization... > PS.

Good network sniffer?

Hi Nanog, Can anyone recommend a good network monitor that can replay captured packets? Windows or *nix. Free is great, commercial is ok too. TIA, Ben

You should also take a look at EtherPeek http://www.wildpackets.com/products/etherpeek_nx. It has more power than Sniffer Pro and comes at a reasonable price. I like that you can analyze packets while the trace is still running.
