hwMemLgFree
Module: A3COM-HUAWEI-LswDEVM-MIB
OID (symbolic): A3COM-HUAWEI-LswDEVM-MIB::hwMemLgFree
OID (numeric): 1.3.6.1.4.1.43.45.1.6.1.2.1.1.5
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The largest free size of the contiguous area in the memory. The unit is byte.
What is hwMemLgFree?
This OID reports an integer byte count of the largest contiguous block of free memory available for allocation. For network devices, this metric is critical because many operations require large contiguous blocks; insufficient contiguous memory can cause failures despite total free memory appearing adequate. Example value: 268435456, representing a largest contiguous free block of 256 MB.
