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.
