hwBuffer512Free
Module: A3COM-HUAWEI-MLSR-SYSTEM-MIB
OID (symbolic): A3COM-HUAWEI-MLSR-SYSTEM-MIB::hwBuffer512Free
OID (numeric): 1.3.6.1.4.1.43.45.1.2.2.5.38
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Contains the number of free 512 byte buffers.
What is hwBuffer512Free?
This OID reports how many 512-byte buffers are currently unused and available for new packets. High utilization (few free buffers) signals congestion and increased packet drop risk. If free buffers drop from 4800 to 200, it means the device is under heavy load and may soon discard incoming packets.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.45.1.2.2.5.38 snmpwalk -v2c -c public <target> A3COM-HUAWEI-MLSR-SYSTEM-MIB::hwBuffer512Free
Get a specific instance (index 1):
