Module: NETSWITCH-DMA-MIB

OID (symbolic): NETSWITCH-DMA-MIB::hpDMAMissBufCnt

OID (numeric): 1.3.6.1.4.1.11.2.14.11.5.1.2.2.20

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: This counter is incremented when buffer allocation fails.

What is hpDMAMissBufCnt?

Count of times buffer allocation failed on the switch's DMA engine. A nonzero and growing value points to memory/buffer pressure that could be causing dropped frames beyond just transmit-ring overflow.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.5.1.2.2.20
snmpwalk -v2c -c public <target> NETSWITCH-DMA-MIB::hpDMAMissBufCnt

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.5.1.2.2.20.1
snmpget -v2c -c public <target> NETSWITCH-DMA-MIB::hpDMAMissBufCnt.1
