Troubleshooting System Management Issues
The system management features of the Cisco Nexus 5000 Series switch allow you to monitor and
manage your network for efficient device use, role-based access control, SNMP communications,
diagnostics, and logging.
This chapter describes how to identify and resolve problems that can occur with system management and
the Cisco Nexus 5000 Series switch.

SNMP memory usage continuously increasing
The
show proc mem | inc snmp
command shows continuously increasing SNMP memory usage.
Possible Cause
SNMP memory usage increases when SNMP requests are processed from different monitoring stations.
Typically, this situation stabilizes over time. If the memory increases continuously without stabilizing,
then some of the SNMP requests are causing a memory leak.
Solution
Review the output from the
show system internal snmp mem-stats detail
command.
Take example snapshots with the following commands while processing SNMP requests:
•
show clock
•
show system internal mem-stats detail
•
show tech snmp
