Description
dellNetSecureMacIfIndex 1.3.6.1.4.1.6027.3.31.1.3.1.1.3 read-only Shows in which interface the
dellNetSecureMacAddress is
configured or learnt.
dellNetSecureMacAddrType 1.3.6.1.4.1.6027.3.31.1.3.1.1.4 read-only Indicates if the secure MAC address is
configured as a static, dynamic, or
sticky.
Viewing the Details of MAC addresses
You can retrieve the dellNetSecureMacAddrType details, use the snmpwalk command.
To retrieve the dellNetSecureMacAddrType on a MAC address (00:00:00:00:11:11) learnt or configured on a VLAN 10, use
the following command.
snmpwalk -v 2c -c public 10.16.129.24 1.3.6.1.4.1.6027.3.31.1.3.1.1.4.6.0.0.0.0.17.17.10
SNMPv2-SMI::enterprises.6027.3.31.1.3.1.1.4.6.0.0.0.0.17.17.10 = INTEGER: 1
Configuring SNMP traps for new MAC learning or
station–move
You can configure the system to send SNMP MAC notifications from the Dell EMC Networking OS.
To configure the system to send SNMP MAC-notifications, use the following command:
● Enable MAC-notification traps.
CONFIGURATION mode
snmp-server traps mac-notification
○ Trap messages are generated only for the new MAC and for the MAC that is learnt for the first time in the system. If
same MAC is learnt on different vlan–ids, then the system does not generate trap messages.
○ If station–move is detected within 3 seconds, then the system generates station–move trap messages and beyond 3
seconds, you cannot see any SYSLOG messages in the system. In continuous station–move, the system generates only 4
station–move trap messages and after every 1 minute, the system generates SYSLOG/trap messages.
○ If there is MAC flooding, only 50 MACs are covered in the trap messages in 1 second and other MAC’s learnt in the
system are processed in the next cycle.
NOTE:
For the VLT-LAG interfaces, the snmp-server traps mac-notification command should be enabled on
both the interfaces. If the command is configured only on one VLT node, then you cannot see any VLT mismatch in the
system. The snmp-server traps mac-notification is not visible under ICL interface and no TRAPS are
supported.
