Module: JUNIPER-CHASSIS-FWDD-MIB
OID (symbolic): JUNIPER-CHASSIS-FWDD-MIB::jnxFwddDmaMemUsage
OID (numeric): 1.3.6.1.4.1.2636.3.34.1.4
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The FWDD DMA Memory utilization in percentage. Zero if unavailable or inapplicable.
What is jnxFwddDmaMemUsage?
This read-only Gauge32 reports the FWDD DMA (Direct Memory Access) memory utilization as a percentage, reading zero if unavailable or not applicable. An admin monitors this to check whether the forwarding hardware's DMA memory, used for buffering packets during forwarding, is nearing exhaustion under heavy traffic load. A value near 100 percent during peak traffic would suggest the router's DMA buffering resources are becoming a bottleneck.
