Well, to be exact, the Chinese are generally superstitious

Hi,
Conversely, 8 is considered to be associated with good

SuSE 8.2 was actually very good - it's been downhill ever
since, although I'm still a loyal follower :-).
Okay, really going off-topic now :-).

Hi,
But yes, splurging a 30gig hard-disk image out over multicast with TTL=1
on the packets will definitely cause TTL-exceeded problems ;o)
bonus points++ for the application using a global multicast address too.
nice.

Hi,
Not to fault Cisco, or anyone else for that matter but shouldn't switches
that cost a quarter of a million dollars be able to protect themselves from
these sorts of things just as a default?
turn off multicast for that VLAN - its its TTL=1 then it didnt really want to

We currently monitor web access from our campus with a VACL capture,
picked up by a server-class machine with a 10gig port. Hardware is
sup720, and our internet links are 10gig, doing well over 1gbit/sec.
For various reasons this solution is unsatisfactory; the VACL doesn't
work well and
We beta tested the GigaMon platform and for the most part it does what
it claims it can do; basically takes a span feed and fans it out for
analysis; in the end it was just too $$pricey$$ ( ~$100K USD); seems
like the target mkt are carriers and large service providers.

It's complicated, but seemingly the 6500 won't VACL-capture IPv6 traffic
which it's also routing. It could be a bug, but as I say we've had other
problems
What code are you running on the Sup720 (3bxl ? I assume) ??

12.2(33)SXI, but we've seen other problems on other versions; I don't
have an exhaustive list, to hand.
The config is something along the lines of:
vlan access-map v6_Capture 10
match mac address PERMIT_ANY
There's also the Citrix Wan Scaler appliance (old Orbital Data) and the
