The system image can also be retrieved by performing an SNMP walk on the following OID: MIB Object is
chSysSwModuleTable and the OID is 1.3.6.1.4.1.6027.3.10.1.2.8.
Monitor Port-Channels
To check the status of a Layer 2 port-channel, use f10LinkAggMib (.1.3.6.1.4.1.6027.3.2). In the following example, Po 1 is a
switchport and Po 2 is in Layer 3 mode.

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.
Troubleshooting SNMP Operation
When you use SNMP to retrieve management data from an SNMP agent on a Dell 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.
