Hi APICs (Application Policy Infrastructure Colleagues),I'm finding,http://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c07-732033.html... thrilling reading. I understand ACI use...

I understand with Cisco router QoS that the non-FIFO QoS configured with MQC is only engaged when the tx-ring tells IOS that there is congestion.1) How can I tell if this is happening now? The show controllers command can tell you the size of the tx-...

We're wanting to apply antispoofing on an interface which has a default route pointing out of it.Does this mean, for traffic ingress to this port, no matter what the source IP address is, the default route will satisfy the condition that there is a r...

In original posting both these show the wrong units,1,500,000 b/s.a single TCP session cannot consume more then 1.5 Mbps The units for bw x Delay product are bits or bytes. bits x sec = bits----sec ... the seconds cancel each other out

Hi Joseph,Thankyou for your reply. I think there is a misunderstanding. The scenario is not "if you have about 3x the average needed bandwidth.". As we know without congestion QoS is essentially a mute point.I'll phrase it differently.I think Cisco a...

Thanks heaps Daniel. This reminds me of the Collisions counter in the output of the SHOW INTERFACE for token ring interfaces and many other examples like it. Look forward for hearing from Doc Team via yourself.

Thankyou Joseph Doherty ... you have come closest to answering my questions. By what show command (and by looking at which part of the output) assuming no packets are being dropped, can I tell that the queues have non-zero depth.

QoS - realtime traffic must be less than one-third of link bandwidth capacity

ACI & 'mpls'

QoS - how do you know there's congestion?

ACL CPU impact C3845 - 'any' or specific host addr

uRPF with default route

In original posting both

Hi Joseph,Thankyou for your
