Notification ConfigurationsConfiguring SNMP & RMON
CPU Utilization Triggered when the CPU utilization exceeds 80%.
Memory Utilization Triggered when the memory utilization exceeds 80%.
Flash Operation Triggered when flash is modified during operations such as backup, reset,
firmware upgrade, and configuration import.
VLAN Create/Delete Triggered when certain VLANs are created or deleted successfully.
IP Change Monitors the changes of interfaces’ IP addresses. The trap can be triggered
when the IP address of any interface is changed.
Storm Control Monitors whether the storm rate has reached the limit that you have set.
The trap can be triggered when the Strom Control feature is enabled and
broadcast/multicast/unknown-unicast frames are sent to the port with a rate
higher than what you have set.
Rate Limit Monitors whether the bandwidth has reached the limit you have set. The trap
can be triggered when the Rate Limit feature is enabled and packets are sent
to the port with a rate higher than what you have set.
LLDP The trap includes the following sub-traps:
LLDP RemTablesChange: Indicates that the switch senses an LLDP topology
change. The trap can be triggered when adding or removing a remote device,
and when the information of some remote devices is aged out or cannot be
stored into the switch because of insufficient resources. This trap can be
used by an NMS to trigger LLDP remote systems table maintenance polls.
LLDP TopologyChange: Indicates that the switch senses an LLDP-MED
topology change (the topology change of media endpoints). The trap can be
triggered when adding or removing a media endpoint that supports LLDP,
such as an IP Phone. An LLDP Remtableschange trap will be also triggered
every time LLDP Topologychange trap is triggered.
Loopback Detection Triggered when the Loopback Detection feature is enabled and a loopback is
detected or cleared.
Spanning Tree Indicates spanning tree changes. The trap can be triggered in the following
situations: a port changes from non-forwarding state to forwarding state or
the other way round; a port receives a TCN (Topology Change Notification)
BPDU or a Configuration BPDU with the TC (Topology Change) bit set.
