I would like to ask you do you know or did someone meet whit this issue on CMTS 7246VXR IOS : ubr7200-ik9su2-mz.123-23.BC10.bin
Issue is that CMTS sends DHCP packet with Hardware Code Type 0 and it should be 1 , so that huawei router reports this error message.
Line 24887: Sep 11 2014 01:24:47+02:00 DST PG-NPE1 %%01SNOOPING/4/HTYPEERR(l):Slot=5,Vcpu=0;The type of hardware address in DHCP packet received from interface GigabitEthernet5/0/1.1001 VLAN 1001 was wrong!
RFC 2131 Dynamic Host Configuration Protocol March 1997
DHCP clarifies the interpretation of the 'siaddr' field as the
address of the server to use in the next step of the client's
bootstrap process. A DHCP server may return its own address in the
'siaddr' field, if the server is prepared to supply the next
bootstrap service (e.g., delivery of an operating system executable
image). A DHCP server always returns its own address in the 'server
FIELD OCTETS DESCRIPTION
----- ------ -----------
op 1 Message op code / message type.
1 = BOOTREQUEST, 2 = BOOTREPLY
htype 1 Hardware address type, see ARP section in "Assigned
I don't see the problem based on RFC2132 or RFC5494.
The client identifier MAY consist of type-value pairs similar to the 'htype'/'chaddr' fields defined in . For instance, it MAY consist of a hardware type and hardware address. In this case the type field SHOULD be one of the ARP hardware types defined in STD2 . A hardware type of 0 (zero) should be used when the value field contains an identifier other than a hardware address (e.g. a fully qualified domain name).
May be the CMTS is doing a DHCP Inform request with is FQDN in the adresse instead of hardware address.
