Nexus9000 C93120TX Chassis - NVRAM

[jon_panes24]

Hi All,

I am wondering how can I view the used/free/total space of the NVRAM on this Nexus Platform

cisco Nexus9000 C93120TX Chassis

NXOS: version 7.0(3)I4(5)

On some other cisco devices there is the command: dir nvram:/

Using dir on the device only shows these directories/filesystems:

  bootflash:  Directory or filename
  debug:      Directory or filename
  log:        Directory or filename
  logflash:   Directory or filename on log flash
  usb1:       Directory or filename
  usb2:       Directory or filename
  volatile:   Directory or filename

I do not belive you can view NVRAM usage, generally it meant to use for configuraiton / Log file / switch reset.

We are monitoring the switch via SNMP and using this OID: 

CISCO-ENTITY-EXT-MIB::ceExtNVRAMUsed

From the description on CISCO-ENTITY-EXT-MIB.my, the value that is being returned is the one on the bootflash://, so is the naming misleading on this one? 

ceExtNVRAMUsed OBJECT-TYPE
    SYNTAX          Unsigned32
    UNITS           "bytes"
    MAX-ACCESS      read-only
    STATUS          current
    DESCRIPTION
        "Number of bytes of NVRAM in use. This object
        is irrelevant if ceExtNVRAMSize is 0." 
    ::= { ceExtPhysicalProcessorEntry 3 }

Usage for bootflash://
 2044936192 bytes used

Sure that not make any sense for me.
