症狀

A message will be registered on the log as shown below filling switch buffer logs

General[procLOG]: l7_ns_mibs.c(XXXX) XXXXXXXX %% ERR truncating integer value > 32 bits

The impact will be the following one:

  • There is no functional impact on the switch 
  • Wrong uptime is seen while polling for switch uptime.
  • Log messages as shown below fills buffer logs
Sample log message
  
Mar 22 21:39:51 General[procLOG]: l7_ns_mibs.c(XXXX) XXXXXXXX %% ERR truncating integer value > 32 bits

原因

  • If the switches uptime is more than 497 days, this message would be output when snmp polling is done to bellow MIB or OID
SNMP MIB : agentInventoryUnitUpTime
SNMP OID : 1.3.6.1.4.1.674.10895.5000.2.6132.1.1.13.2.2.1.14
  • The reason for this log message is because MIB agentInventoryUnitUpTime is Counter32, which means it is a 32-bit integer counter. If 497 days of switch uptime is crossed, then its corresponding integer value exceeds 32 bit and hence value overflows.

解析度

It's advised to take the following actions mentioned below.

    1. From 6.8.1.1 this log message level is DEBUG instead of ERROR. Hence it can be upgrades to any firmware to 6.8.1.1 and above.

     2.Stop polling to    
SNMP MIB : agentInventoryUnitUpTime
SNMP OID : 1.3.6.1.4.1.674.10895.5000.2.6132.1.1.13.2.2.1.14
                                                                                      
     3. Restart the switch so that the uptime value resets.
