Issue/Introduction

Recently upgraded Cisco network device on latest IOS Version.

However after up gradation of network device IOS started receiving alerts related to physical memory processor physical Entity 598 of devices from snmpcollector probe 

 

 

Environment

• UIM: 20.3.3
• SNMP collector: 4.03
• Network device details.
• Make : Cisco
• Model: C92348GC-X

Cause

Since the bootflash memory is over 4GB, it needs more than 32-bit counter to capture the value.

The OIDs used earlier are Unsigned32, that's why the total bootflash size captured is a mismatch. 

Previously used OIDs:

ceExtNVRAMSize :: 1.3.6.1.4.1.9.9.195.1.1.1.2.598 = 1596829696 :: 1596829696     <<<<

ceExtNVRAMUsed :: 1.3.6.1.4.1.9.9.195.1.1.1.3.598 = 3858964480 :: 3858964480    <<<<

Suggested for the below OIDs which supports 64 bit counters.

ceExtHCNVRAMSize       - 1.3.6.1.4.1.9.9.195.1.1.1.7

ceExtHCNVRAMUsed       - 1.3.6.1.4.1.9.9.195.1.1.1.9

Resolution

Certification team will fix the Memory Utilization issue by adding two new Counter64 OIDs

- ceExtHCNVRAMSize 1.3.6.1.4.1.9.9.195.1.1.1.7
- ceExtHCNVRAMUsed 1.3.6.1.4.1.9.9.195.1.1.1.9
