cpqNicIfPhysAdapterDma
Module: CPQNIC-MIB
OID (symbolic): CPQNIC-MIB::cpqNicIfPhysAdapterDma
OID (numeric): 1.3.6.1.4.1.232.18.2.3.1.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The number of the DMA channel used for this physical hardware interface. The number -1 indicates that this device does not use a DMA channel or this information is unavailable.
What is cpqNicIfPhysAdapterDma?
This read-only value reports the DMA channel number used by this physical adapter, with -1 meaning the device doesn't use a DMA channel or the information is unavailable. An admin would check this mainly on legacy hardware when troubleshooting DMA channel conflicts. For example, seeing -1 here on a modern NIC confirms it doesn't rely on a dedicated DMA channel at all.
