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.

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. |
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.

- 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.

- 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 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.

Description
DHCP/4/DHCPPD_ROUTE_EXCEED: OID [OID] The number of PD route for DHCPv6 relay reached the maximum.
The number of PD route for DHCPv6 relay reached the maximum.
Possible Causes
The number of PD routing entries on the DHCPV6 relay agent is limited. When there are an excessive number of online DHCPv6 PD clients, the number of PD routing entries generated on the DHCPv6 relay agent for such DHCPv6 PD clients may exceed the upper limit. As a result, no more PD routing entry can be generated on the DHCPv6 relay agent. The DHCPv6 relay agent has no PD routing entry corresponding to a client. As a result, service data of the client fails to be forwarded.
