hpnicfLswSlotPktBufFree
Module: HPN-ICF-LSW-DEV-ADM-MIB
OID (symbolic): HPN-ICF-LSW-DEV-ADM-MIB::hpnicfLswSlotPktBufFree
OID (numeric): 1.3.6.1.4.1.11.2.14.11.15.8.35.18.4.3.1.15
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The number of packet buffers available for internal VME transfers or external transfers, respectively. Because switch operations and application software modules impose some overhead on global memory buffers, the number of buffers available for data transfers is less than the total number of buffers allocated when the switch boots.
What is hpnicfLswSlotPktBufFree?
This OID holds the number of free memory blocks available for the switch to buffer incoming network packets. When this number gets very low, the switch will start dropping packets because it runs out of temporary storage. A network operator monitoring this value watches for congestion and plans upgrades when free buffers consistently drop below 20%.
