SNMP Chapter 7 Troubleshooting System Management Issues Send document comments to [email protected]. SNMP not responding No response or delayed response for SNMP request. Possible Cause If the switch CPU utilization is high during the SNMP operations such as GET, GETNEXT and WALK, the response may be very slow or there is no responsethat results in a time-out. Solution While SNMP is not responding, check CPU utilization with the following commands: • show proc cpu history • show proc cpu sort The output from this command shows which Nexus 5000 component is using the greatest amount of CPU resources. SNMP not responding and show snmp command reports SNMP has timed out SNMP is not responding and the show snmp command reports that SNMP has timed out. Possible Cause The SNMP process might have exited, but the process did not crash. Solution Use show system internal sysmgr service name snmpd command which should show the state to be"SRV_STATE_HANDSHAKED. Example: Service "snmpd" ("snmpd", 74): UUID = 0x1A, PID = 4131, SAP = 28 State: SRV_STATE_HANDSHAKED (entered at time Mon Jun 14 17:12:15 2010). Restart count: 1 Time of last restart: Mon Jun 14 17:12:14 2010. The service never crashed since the last reboot.

Troubleshooting System Management Issues
SNMP
SNMP not responding
No response or delayed response for SNMP request.
Possible Cause
If the switch CPU utilization is high during the SNMP operations such as GET, GETNEXT and WALK,
the response may be very slow or there is no responsethat results in a time-out.
Solution
While SNMP is not responding, check CPU utilization with the following commands:
•
show proc cpu history
•
show proc cpu sort
The output from this command shows which Nexus 5000 component is using the greatest amount of
CPU resources.
SNMP not responding and show snmp command reports SNMP has timed out
SNMP is not responding and the
show snmp
command reports that SNMP has timed out.
Possible Cause
The SNMP process might have exited, but the process did not crash.
Solution
Use
show system internal sysmgr service name snmpd
command which should show the state to
be“SRV_STATE_HANDSHAKED.
Example:
Service "snmpd" ("snmpd", 74):
UUID = 0x1A, PID = 4131, SAP = 28
State: SRV_STATE_HANDSHAKED (entered at time Mon Jun 14 17:12:15 2010).
Restart count: 1
Time of last restart: Mon Jun 14 17:12:14 2010.
The service never crashed since the last reboot.
Tag = N/A
Plugin ID: 0
Not able to perform SNMP SET operation
The following error appears when trying to perform the SNMP SET operation:
bash-2.05b$ snmpset -v2c -c private 10.78.25.211 .1.3.6.1.4.1.9.9.305.1.1.6.0 i 1
Error in packet.
Reason: notWritable
Possible Cause
The SNMP community does not have write permission.
Solution
Check the output of the
show snmp community
command to ensure that the write permission is enabled.
Example:
Community
Group / Access
context
acl_filter
