This looks badly broken, and the problem is the sflow output from the 
switch.

Fields #3 and #4 (25, 0) are the SNMP indexes of the source and 
destination interfaces of the switch.  The destination interface ID is 
set to 0, which is impossible because SNMP IDs are indexed from 1 upwards.

Fields #8 and #9 are the source and destination VLAN id.  Neither should 
be zero because dot1q vlan ID 0 does not exist.

I think you need to talk to Huawei about this.  Each sflow record should 
contain a legitimate ifIndex ID for both the source and destination 
interface, and should also contain valid VLAN IDs, which are provided by 
the Sflow Extended Switch Data field in the sflow header.  This switch 
provides incorrect data for both these fields, which is a bug.
