Context
After the LLDP trap function is enabled, the switch sends traps to the NMS in one of the following
cases:
l The LLDP function is enabled or disabled globally. The traps are
LLDP_1.3.6.1.4.1.2011.5.25.134.2.1 hwLldpEnabled and
LLDP_1.3.6.1.4.1.2011.5.25.134.2.2 hwLldpDisabled.
l The local management address changes. The trap is LLDP_1.3.6.1.4.1.2011.5.25.134.2.5
hwLldpLocManIPAddrChange.
l Neighbor information changes. The trap is LLDP_1.0.8802.1.1.2.0.0.1
lldpRemTablesChange. A trap is not generated if the management address of a neighbor
changes.
The LLDP trap function is applied to all interfaces. The LLDP trap function can take effect no
matter whether the LLDP function is enabled globally. If the network topology is unstable,
disable the LLDP function to prevent frequent trap sending.
Procedure

Step 2 Run:
snmp-agent trap enable feature-name lldptrap
