Configuring SNMP & RMON Notification Configurations

Step 2 snmp-server traps { bandwidth-control | cpu | flash | lldp remtableschange | lldp

topologychange | loopback-detection | storm-control | spanning-tree | memory }

Configure parameters of extended traps supported on the switch.

bandwidth-control:

The trap is used to monitor whether the bandwidth has reached the

limit that you have set. The trap is disabled by default. The trap can be triggered when the

feature is enabled and packets are sent to the port with a rate higher than what you have

set.

cpu:

The trap is used to monitor the load status of the switch CPU. And the trap is disabled

by default. The trap can be triggered when the utilization rate of the CPU has exceeded the

limit that you have set. The limit of CPU utilization rate for the switch is 80% by default.

flash:

The trap is used to monitor whether the flash is modified. And the trap is disabled

by default. The trap can be triggered when the flash is modified by saving configurations,

factory resetting, upgrading and importing configurations.

lldp remtableschange: A lldp RemTablesChange notification is sent when the value of lldp

StatsRemTableLastChangeTime changes. It can be utilized by an NMS to trigger LLDP

remote systems table maintenance polls.

lldp topologychange: A notification generated by the local device to sense the change in

the topology that indicates a new remote device attached to a local port, or a remote device

disconnected or moved from one port to another.

loopback-detection:

The feature is used to detect loopbacks. And the trap is disabled by

default. The system will generate the trap when a loopback is detected or cleared.

storm-control: The feature is used to monitor network storms. And the trap is disabled by

default. The system will generate the trap when the rate of broadcast or multicast reaches

the limit of storm control.

spanning-tree:

The feature is used to monitor the spanning tree status. And the trap is

disabled by default. The system will generate the trap in the following situations: a port

changes from non-forwarding state to forwarding state or the other way round; a port

receives a packet with TC flag or a TCN packet.

memory: The feature is used to monitor the memory. And the trap is disabled by default.

The system will generate the trap when the memory utilization exceeds 80%.

Step 3 end

Return to privileged EXEC mode.

Step 4 copy running-config startup-config

Save the settings in the configuration file.

The following example shows how to configure the switch to enable bandwidth-control

traps:

Switch#configure

Switch(config)#snmp-server traps bandwidth-control

Switch(config)#end

Switch#copy running-config startup-config
