Module: Juniper-System-MIB

OID (symbolic): Juniper-System-MIB::juniSystemModuleSlotSpan

OID (numeric): 1.3.6.1.4.1.4874.2.2.2.1.3.4.1.7

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The number of slot positions that the expected module spans. Most modules are only one slot wide, but some require extra space or backplane resources. These modules are identified as being in the lower numbered slot and spanning across the higher numbered slot(s).

What is juniSystemModuleSlotSpan?

This reports how many physical slot positions the expected module occupies, since some modules need extra backplane space and span into higher-numbered slots beyond their base position. Operators use it to understand why adjacent slots appear occupied by the same card.
