cpqHoIfPhysMapDma
Module: CPQHOST-MIB
OID (symbolic): CPQHOST-MIB::cpqHoIfPhysMapDma
OID (numeric): 1.3.6.1.4.1.232.11.2.5.1.1.5
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 cpqHoIfPhysMapDma?
This integer reports the DMA channel used by this interface's physical hardware, with -1 meaning no DMA channel is used or the information is unavailable. It's diagnostic data for legacy hardware troubleshooting where DMA channel conflicts between devices can cause data corruption or failures. For example, an administrator would check this alongside other cards' DMA settings when investigating unexplained data errors on an older server's network adapter.
