snmp-agent trap enable feature-name mstp

Function

The snmp-agent trap enable feature-name mstp command enables the trap function for the MSTP module.

The undo snmp-agent trap enable feature-name mstp command disables the trap function for the MSTP module.

By default, the trap function is disabled for the MSTP module.

Parameters

Parameter	Description	Value
trap-name	Enables the traps of MSTP events of specified types.	-
hwmstpibridgelostrootprimary	Enables the device to send trap when the current device is no longer the root bridge.	-
hwmstpiedgeportchanged	Enables the device to send trap when the edge port that is not enabled with the BPDU guard function is no longer the edge port after receiving BPDUs.	-
hwmstpiportbpduguarded	Enables the device to send trap when the edge port enabled with the BPDU guard function can receive BPDUs.	-
hwmstpiportloopguarded	Enables the device to send trap when the port enabled with the loop guard function does not receive any BPDU in a specified period.	-
hwmstpiportrootguarded	Enables the device to send trap when the port enabled with the root guard function receives BPDUs with higher priorities.	-
hwmstpiportstatediscarding	Enables the device to send trap when the port status changes to Discarding.	-
hwmstpproloopbackdetected	Enables the device to send trap when port detected loopback, block the port.	-
hwmstpiportstateforwarding	Enables the device to send trap when the port status changes to Forwarding.	-
hwmstpitcguarded	Enables the device to send trap when the number of TC packets received by the instance enabled with the TC guard function exceeds the upper limit.	-
hwmstpportcountthreshold	Enables the device to send trap when the number of STP interfaces that were Up on a device exceeded the upper threshold.	-
hwmstpportcountthresholdresume	Enables the device to send trap when the number of STP interfaces that were Up on a device fell below the lower threshold.	-
hwmstppronewbridgelostrootprimary	Enables the device to send trap when in the MSTP process the device is no longer the root bridge.	-
hwmstppronewedgeportchanged	Enables the device to send trap when in the MSTP process the edge port that is not enabled with the BPDU guard function is no longer the edge port after receiving BPDUs.	-
hwmstppronewportbpduguarded	Enables the device to send trap when in the MSTP process the port enabled with the BPDU guard function can receive BPDUs.	-
hwmstppronewportloopguarded	Enables the device to send trap when in the MSTP process the port enabled with the loop guard function does not receive any BPDU in a specified period.	-
hwmstppronewportrootguarded	Enables the device to send trap when in the MSTP process the port enabled with the root guard function receives BPDUs with higher priorities.	-
hwmstppronewportstatediscarding	Enables the device to send trap when in the MSTP process the port status changes to Discarding.	-
hwmstppronewportstateforwarding	Enables the device to send trap when in the MSTP process the port status changes to Forwarding.	-
hwmstpprorootchanged	Enables the device to send trap when the root bridge changes.	-
hwmstpprotcguarded	Enables the device to send trap when in the MSTP process the number of TC packets received by the instance enabled with the TC guard function exceeds the upper limit.	-
newroot	Enables the device to send trap when the current device is elected as the root bridge.	-
topologychange	Enables the device to send trap when the topology changes.	-
hwmstpprorootlost	Enables the device to send trap when it loses its root bridge role in an MSTP process.	-
hwmstpprorootresume	Enables the device to send trap when it has its root bridge role resumed in an MSTP process.	-

Usage Guidelines

The MSTP module is not configured with the function of excessive traps. To enable the traps of one or more events, you can specify trap-name.

Example

# Enables the device to send trap when the current device is no longer the root bridge.
