Troubleshooting SNMP Operation
When you use SNMP to retrieve management data from an SNMP agent on a Dell EMC Networking router, take into account
the following behavior.
When you query an IPv4 icmpMsgStatsInPkts object in the ICMP table by using the snmpwalk command, the output for
echo replies may be incorrectly displayed. To correctly display this information under ICMP statistics, use the show ip
traffic command.
When you query an icmpStatsInErrors object in the icmpStats table by using the snmpget or snmpwalk command, the
output for IPv4 addresses may be incorrectly displayed. To correctly display this information under IP and ICMP statistics,
use the show ip traffic command.
When you query an IPv4 icmpMsgStatsInPkts object in the ICMP table by using the snmpwalk command, the echo
response output may not be displayed. To correctly display ICMP statistics, such as echo response, use the show ip
traffic command.
Transceiver Monitoring
To retrieve and display the transceiver related parameters you can perform a snmpwalk transceiver table OID to retrieve
transceiver details as per the MIB. This enables transceiver monitoring and identification of potential issues related to the
transceivers on a switch.
Ensure that SNMP is enabled on the device before running a query to retrieve the transceiver information.
If Tx/Rx power, temperature, current, or voltage is not supported on optics, snmp walk returns a null ("") value.
If optics are not inserted in a port, empty string is displayed.
