DHCP_1.3.6.1.4.1.2011.5.25.112.2.1 hwDhcpSnpChaddrAlarm

Description

DHCP/1/REQMACTRAP:OID [OID] The number of the discarded DHCP packets in which the CHADDR field is inconsistent with the source MAC address exceeds the threshold on the interface. (IfIndex=[INTEGER], VlanIndex=[INTEGER], Interface=[OCTET], VlanID=[INTEGER], DiscardedNumber=[INTEGER])

The number of discarded DHCP packets in which the CHADDR field and the source MAC address mismatched exceeded the threshold on the interface.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.112.2.1 Critical equipmentAlarm(5)

Parameters

Name Meaning
OID Indicates the MIB object ID of the alarm.
IfIndex Indicates the interface index.
VlanIndex Indicates the VLAN index.
Interface Indicates the interface name.
VlanID Indicates the VLAN ID.
DiscardedNumber Indicates the number of discarded packets.

Impact on the System

Invalid DHCP packets are discarded.

Possible Causes

The device considers DHCP packets in which the CHADDR field does not match the source MAC address as invalid DHCP packets.

Procedure

  • Configure port mirroring to obtain DHCP packets received by the interface. Check whether DHCP packets in which the CHADDR field does not match the source MAC address are attack packets.

    • If a user connected to the interface sends a large number of DHCP packets in which the CHADDR field does not match the source MAC address, the user is an unauthorized user and the DHCP packets are attack packets. The device discards the attack packets. Check the attack source based on the source address.
    • If users connected to the interface do not send a large number of DHCP packets in which the CHADDR field does not match the source MAC address, DHCP packets sent by the users are not attack packets. To ensure that the users pass the check, cancel the dhcp snooping check dhcp-chaddr enable command configuration on the interface.

Parameters

Name Meaning
OID Indicates the MIB object ID of the alarm.
IfIndex Indicates the interface index.
VlanIndex Indicates the VLAN index.
Interface Indicates the interface name.

Impact on the System

Invalid DHCP packets are discarded.

Possible Causes

Bogus DHCP server attacks occurred.

Procedure

  1. Capture packets on the interface to check whether a bogus DHCP server attack occurs on this interface.

    • Check whether the DHCP server address in the received DHCP Reply packet is the specified server address. If not, the DHCP server is a bogus server. Because the invalid DHCP packets have been discarded, no action is required.
    • If the DHCP server is a valid server and needs to be used, run the dhcp snooping trusted command on the interface to configure it as a trusted interface.

  2. Configure port mirroring to obtain DHCP packets received by the interface. Check users' IP addresses and MAC addresses in DHCP Request packets that do not match the binding table.

    • If a user connected to the interface sends a large number of DHCP Request packets that do not match the binding table, the user is an unauthorized user and the DHCP Request packets are attack packets. The device discards the attack packets. Check the attack source based on the user's IP address or MAC address.
    • If users connected to the interface do not send a large number of DHCP Request packets that do not match the binding table, DHCP packets sent by the users are not attack packets. To ensure that the users pass the check, cancel the dhcp snooping check dhcp-request enable command configuration on the interface.

    • If a user connected to the interface sends a large number of DHCP packets, the DHCP packets are attack packets. The device discards the attack packets. Check the attack source based on the source address.
    • If users connected to the interface do not send a large number of DHCP packets, the DHCP packets are not attack packets. Determine whether to run the dhcp snooping check dhcp-rate rate or dhcp snooping check dhcpv6-rate rate command to adjust the upper rate limit of DHCPv4 or DHCPv6 packets or run the dhcp snooping alarm dhcp-rate threshold threshold or dhcp snooping alarm dhcpv6-rate threshold threshold command to adjust the alarm threshold of discarded DHCPv4 or DHCPv6 packets according to the actual situation and user requirements.
