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

Error in packet.
