I?m having a hard time to understand the values of Normal Burst and Exceed Burst. I know that those values are in Bytes and that the Token Bucket (same as Bc+Be) is used as a metaphor to explain how tokens are removed from the bucket in a relation to a packet size, and also tokens are added to the bucket every TC.
Also I think that I understand the logic behind the Policing compound and actual debt algorithm, BTW in Table 1 of this link http://www.cisco.com/en/US/products/sw/iosswrel/ps5014/products_feature_guide_chapter09186a00800ca4f2.html at Pkt 6 the Actual Debt is wrong, it should be 3 and not 2 as the description says. Also that the Token measurement method in Class Based Policing separate token buckets for burst-normal and burst-max and that in the legacy configuration (car) single token bucket for burst-normal and burst-max (definitions of RFC 2697 and 2698)
but I got stuck in the implementation and interpretation :S
For example yesterday I lab something really stupid, Running RIP in all interfaces (so reachability is not a problem here)
Lo0- R3 ?? serial ?? R1 ----- Ethernet ---- R2
I changed the point-to-point circuit clock rate to different values for testing, and I did a ping with different packet sizes from R2 to R3 lo0, and also applied at R1 a rate-limiter with different values, but I could not interpret the values showed show int XX rate, I saw packets fragmented, I saw different values for the rate, I got frustrated.
Is there any ordered way to test this and finally understand it
I think that an example using ping with different sizes and with different policing values would be very helpful, is there any link out there with that, or I'm asking to much, if so please sorry for the spam
I mean I can not afford to buy more books, because my budget is in 0 now, so please if you do not mind, shed a light here.
I do not understand well yet what the Word Burst means (in Spanish is something really different of what you can think, is like killing someone :D),
