Module: DELL-NETWORKING-BPSTATS-MIB
OID (symbolic): DELL-NETWORKING-BPSTATS-MIB::bpDropsMMUHOLDrops
OID (numeric): 1.3.6.1.4.1.6027.3.24.2.1.1.1.9
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: No of packets dropped in MMU because of MMU HOL Drops
What is bpDropsMMUHOLDrops?
This Counter64 counts packets dropped in the switch's Memory Management Unit due to head-of-line blocking on a backplane hiGig port. Admins use it to identify internal queue congestion on the fabric side of a leaf-spine chassis rather than on user-facing ports. Sustained growth suggests the backplane buffer for that BP port pipe is being oversubscribed.
