Example of Viewing Changed Interface State for Monitored Ports Layer 3 LAG does not include this support. SNMP trap works for the Layer 2 / Layer 3 / default mode LAG.

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. • Value 0.0 would be returned in case of Tx/Rx power not being supported on the optics. • Empty string would be displayed if optics are not inserted in a port. Example of SNMP Output for Transceiver Monitoring Dell $ snmpwalk -v1 -c public 10.16.150.210 1.3.6.1.4.1.6027.3.11.1.3.1.1 | grep 2106373 SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.1.2106373 = STRING: "Stack-Unit-1 OptionalModule-3 Port-5" SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.2.2106373 = STRING: "Fo 1/3/5" SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.3.2106373 = STRING: "40GBASE-SR4" SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.4.2106373 = STRING: "AVAGO" SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.5.2106373 = STRING: "AFBR-79E4Z-D-FT1" SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.6.2106373 = STRING: "750382760048" SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.7.2106373 = STRING: "0.0" SNMPv2-SMI::enterprises.6027.3.11.1.3.1.1.8.2106373 = STRING: "-2.273117" 866 Simple Network Management Protocol (SNMP)
