Well, to get specific, I think that it will be interesting to see what
happens when the size of the route table exceeds the stock TCAM on the Cisco
Catalyst platform. Before I got to my current employer Cisco sold then
7604s with Sup32s (I hope they weren't more expensive than 6504 chassis
because all they did was change the paint). I'm going to hope that Cisco
comes out with a Sup upgrade that includes the larger TCAM of the 3BXL
without the switch fabric mojo - that's stuff's expensive. The whole thing
really makes me wonder about the value of selling the Cat platform as a
customer edge router...

So are you envisioning ANY sort of aggregation at all? I mean for this to
be at all practical you'd have to have some sort of DWDM aggregation point
or something, wouldn't you? And if that's the case then haven't you just
swapped one kind of equipment for another?

Hardware capture platforms
We've deployed a bunch taps in our network and now we need a platform on
which to capture the data. Our bandwidth is currently pretty low but
I've got 8 links to tap, which means I need 16 ports. Has anyone done any
research on doing accurate packet capture with commodity hardware?

Capture problems with Intel quad cards?
Has anyone had problems with using current Intel quad ethernet cards for packet capture? As a proof-of-concept test we bought an Intel PWLA8494GT and hooked it up to some Network Critical taps. There was a very strange issue with corruption of the captured packets. The *only* issue (but it's a big one) is that the source IP on some captured packets is munged. As far as I can tell that's the *only* issue with the packet captures - no other data is corrupted. Oh, and to rule out other issues: 1. Corruption seen both when using network taps and when using a port span/mirror (so it's not the taps). 2. Corruption *not* seen using the on-board broadcom nics of the test host (so it's not the box). So I'm pretty sure we narrowed it down to the card. We tried the card in an indentical host and saw the same problems. I thought it might be a driver issue - I tried both gentoo and FreeBSD (not sure how different the drivers are) just to see if it mattered at all and it didn't. Much googling didn't show this to be a known issue - just wondering if anyone else has seen it? Other recommendations welcome - the next step is, I suppose, a broadcom-based PCI-X card. (I've got some old pizza boxes I'm trying to repurpose as network probes.) Thanks, John -- John A.

The fact that it's vandalism is VERY annoying. Sadly it also shows how

Re: Pacific Northwest downtime?
Yeah, I saw it too. My traceroute was dying at an IP belonging to Global Crossing and the DNS looked like it was at 11 Great Oaks. I called Comcast to report it, but they just kept saying I should reboot my modem. On Aug 12, 2010, at 11:19 PM, Ashoat Tevosyan wrote: > Never mind, back up!

Yeah, things were wonky for a while. Like the application for programming my
Harmony One couldn't contact Logitech's servers. But since my mail server is
at he.net that was the big thing I noticed. :)
But of course, step one, reboot my modem...*sigh*
