Hey Guys,I'm taking a practice lab for my CCIE and I'm stumped with a basic. Can anyone tell me why I would get 'Encapsulation failures' during a ping when I have defined specifically a DLCI on the frame-relay interface with the 'frame-relay interfa...
Hey Guys,Having a problem with 'ip nat outside source static'. When a client on the outside of the NAT router tries to ping the server on the inside, I can see that traffic to the destination is NATted but return traffic is not being unNATted which ...
Hey Guys,I've been trying to figure out the following configuration and it is starting to make my brian hurt. Specifically is the 'threshold' value for the 'wrr-queue cos-map' command. For example, below we see the command 'wrr-queue cos-map 2 6 0 ...
Hi Guys,Quick question. Does anyone know how to NAT BOTH the source and destination IP address on a router? I've been through several articles and it looks like this functionality is reserved for the ASA firewall but was looking for confirmation.Ne...
Hey Guys,Can anyone tell me if there is a way to check how many hardware queues a particular interface has? I'm just trying to dive into deeper understanding of the architecture and have not found much documentation from cisco on it. I've got a 374...
Thanks guys. I was doing an IPExpert lab in GNS3 and the requirement was to not user sub-interfaces and to ensure inverse-arp was disabled. It does work with inverse-arp enabled. So I guess I'm going to just try the config again using a point-to...
Thank you Shashank!Your explanation is very helpful. Further, it pointed out something else interesting in that drop thresholds are set on CoS values rather then queues. I used to think that you set WRED min and max values on a per queue basis but ...
Milan,I think you are dead on but you math may be a bit off. Tc is 250 ms not 200ms. The reason is Bc is 400k and bps is 16k. So 16000 divided by 400 is 4 meaning that there are 4 250ms time slots transmitting 400bps (Bc). Add the 4 slots togethe...
"I still think that I'm somehow right when what I say "LLQ cannot borrow the full bandwidth" You have set LLQ to 16k and you have 30000bps (which is about 30k) and you already have a drop of 1000bps. If LLQ is allowed to borrow as much bandwidth as i...
