**Table 1** Description of the **display snmp-agent trap feature-name dhcp all** command output
Item	Description
Feature name	Name of the module to which a trap belongs.
Trap number	Number of traps.
Trap name	Name of a trap. Traps on the DHCP module include: hwNomatchSnpBindTblDhcpPktAlarm: The device sends a Huawei proprietary trap when the number of DHCP Request packets that do not match DHCP snooping binding entries and are discarded on an interface exceeds the threshold. hwDhcpSnpChaddrAlarm: The device sends a Huawei proprietary trap when the number of discarded DHCP packets whose CHADDR field differs from the source MAC address exceeds the threshold. hwUntrustedReplyPktAlarm: The device sends a Huawei proprietary trap message when the number of DHCP Reply packets discarded on an untrusted interface exceeds the threshold. hwDhcpPktRateAlarm: The device sends a Huawei proprietary trap message when the number of discarded DHCP packets whose rate exceeds the limit exceeds the threshold. hwSnpUserNumberAlarmIf: The device sends a Huawei proprietary trap message when the number of DHCP access users on an interface exceeds the upper threshold. hwSnpUserNumberAlarmIfResume: The device sends a Huawei proprietary trap message when the number of DHCP access users on an interface falls below the lower threshold. hwSnpUserNumberAlarmVlan: The device sends a Huawei proprietary trap message when the number of DHCP access users in a VLAN exceeds the upper threshold. hwSnpUserNumberAlarmVlanResume: The device sends a Huawei proprietary trap message when the number of DHCP access users in a VLAN falls below the lower threshold. hwSnpUserNumberAlarmGlobal: The device sends a Huawei proprietary trap message when the number of DHCP access users on the device exceeds the upper threshold. hwSnpUserNumberAlarmGlobalResume: The device sends a Huawei proprietary trap message when the number of DHCP access users on the device falls below the lower threshold. hwNdSnpUserNumberAlarmIf: The device sends a Huawei proprietary trap message when the number of ND access users on an interface exceeds the upper threshold. hwNdSnpUserNumberAlarmIfResume: The device sends a Huawei proprietary trap message when the number of ND access users on an interface falls below the lower threshold. hwNdSnpUserNumberAlarmGlobal: The device sends a Huawei proprietary trap message when the number of ND access users on the device exceeds the upper threshold. hwNdSnpUserNumberAlarmGlobalResume: The device sends a Huawei proprietary trap message when the number of ND access users on the device falls below the lower threshold. hwNomatchSnpBindTblDhcpv6PktAlarm: The device sends a Huawei proprietary trap message when the number of DHCPv6 Request packets discarded on an interface because they do not match the binding entries exceeds the threshold. hwNomatchSnpBindTblNDPktAlarm: The device sends a Huawei proprietary trap message when the number of ND packets discarded on an interface because they do not match the binding entries exceeds the threshold. hwSnpRemoteBackupAlarm: The device sends a Huawei proprietary trap message when DHCP snooping binding entries fail to be restored from the remote server. hwSnpRemoteBackupAlarmResume: The device sends a Huawei proprietary trap message when DHCP snooping binding entries are successfully restored from the remote server.
Default switch status	Default status of the trap function: on: The trap function is enabled by default. off: The trap function is disabled by default.
Current switch status	Trap status: on: The trap is enabled. off: The trap is disabled.
