cpqSePcieFunctMaxLinkWidth
Module: CPQSTDEQ-MIB
OID (symbolic): CPQSTDEQ-MIB::cpqSePcieFunctMaxLinkWidth
OID (numeric): 1.3.6.1.4.1.232.1.2.13.2.1.15
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This is the maximum link width for the PCIe device. Value N means N lanes. An entry of 0 indicates the maximum link width could not be determined or the device is not PCIe.
What is cpqSePcieFunctMaxLinkWidth?
This OID reports the maximum PCI Express link width, in lanes, that this device function is capable of, returning 0 if it could not be determined or the device is not PCIe. An admin uses this maximum lane rating as the baseline to compare against the negotiated link width, to judge whether a PCIe device is running at full width or has been constrained by its slot. For example, a device rated for 16 lanes maximum that is placed in a physically shorter slot might only ever negotiate 8 lanes, and comparing both OIDs would reveal that shortfall.
