According to cisco "Slow Drain Device Detection and Congestion Avoidance"
Quote as following
"1 in every 8 credits (with a maximum of 15) is reserved for absolute priority traffic only. All the user and data traffic (which could be high, medium, or low priority) is sent using the remaining shared credits."
Is it just a default or configurable setting? If it is not configurable, how if data traffic congested the link? As data traffic can only use low priority B2B credit, total B2B credit will be remaining non-0 all the time, so Link reset will not occur anyway? How could low priority B2B credit get recovered?
Thanks in advance for any of your help!
