Correct, it's in the ms range.

Hi,
Can anyone with SP experience state why would one choose pipe model over short
pipe model or vice versa for deploying MPLS QoS?
I have been searching the cisco site and other places a for a while to get an
answer.
Any pointers suggests welcome.
Thanks in advance,

Hi,
We're about to expand our use of OSPF PE-CE connections in some
redundant setups, and in that regard I'd be happy to know more precisely
if I can expect all (most) customer devices to repect the DN bit.
As I understand OSPF, all customer routers should just not care about

Got it, so the issue is only for bus traffic and whether all port asic's
grab it (6148 as discussed) or just the tx asic (as you clarified for

Sup2/MSFC2 is same switching paths as 720, only major difference is the common
lack of a switch fabric.

No. Assuming the 6500 isn't a relic with an MSM or Sup1/Sup1A, there
should be no difference in L2 and L3 forwarding performance (
If you have DFC on the linecard, then *everything* is distributed for
traffic ingress on that linecard - L2, L3, ACLs, QoS, Netflow. If
not, then it's centrally processed by the PFC for traffic ingress on
that linecard. There is no "local L2 switching" (or any other local
forwarding decisions)

Hey everyone,
Last week's converstaion on 6500 scalaibility numbers prompted me to
dig back into the performance issues I have on a pair of boxes. I
discovered two issues, both related to the presence of CSMs in the
chassis. An important note about my scenario - I have two basically
identical in
So the question is, is there a difference? I have hundreds of GB's
to backup so if there is a performance difference one way or the
other, I would want to know. The only thing I can see as a
difference is if I trunk the iSCSI vlan, then the traffic never hits
the 6509's routing module. Maybe th

...and that's it. The 2nd reply is dropped. If the client makes the
queries "slowly" they work fine:
