This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

mincir - is used with a map-class and specifies the minimum amount of data sent when there is congestion. mincir is used with adaptive shaping.

Example: The port speed is 256K. The router sending rate is 128K. The router should throttle down to 64K upon the receipt of BECNs.

Solution:

interface serial 0/0
encapsulation frame-relay
frame-relay traffic-shaping
frame-relay class FRAMECLASS
!
map-class frame-relay FRAMECLASS
frame-relay cir 128000
frame-relay mincir 64000
frame-relay adpative-shaping becn (when becn's are received start scaling back to a minimum of mincir)
