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.
Manage VLANs using SNMP
The qBridgeMIB managed objects in Q-BRIDGE-MIB, defined in RFC 2674, allows you to use SNMP to manage VLANs.
Creating a VLAN
To create a VLAN, use the dot1qVlanStaticRowStatus object.
The snmpset operation shown in the following example creates VLAN 10 by specifying a value of 4 for instance 10 of the
dot1qVlanStaticRowStatus object.
> snmpset -v2c -c mycommunity 123.45.6.78 .1.3.6.1.2.1.17.7.1.4.3.1.5.10 i 4
SNMPv2-SMI::mib-2.17.7.1.4.3.1.5.10 = INTEGER: 4
Assigning a VLAN Alias
Write a character string to the dot1qVlanStaticName object to assign a name to a VLAN.

> snmpset -v2c -c mycommunity 10.11.131.185 .1.3.6.1.2.1.17.7.1.4.3.1.1.1107787786 s "My
VLAN"
SNMPv2-SMI::mib-2.17.7.1.4.3.1.1.1107787786 = STRING: "My VLAN"
