Hello, freebsd 11.2/amd64 release net-snmp-5.7.3_18 net-snmpd returns incomplete MAC addresses in IF-MIB::ifPhysAddress, the first octet is always "0". $ snmpwalk -v 2c -c "xxx" localhost 1.3.6.1.2.1.2.2.1.6 IF-MIB::ifPhysAddress.1 = STRING: 0:36:9f:93:7d:f8 IF-MIB::ifPhysAddress.2 = STRING: 0:36:9f:93:7d:fa IF-MIB::ifPhysAddress.3 = STRING: 0:f4:bb:ef:c8:e4 ... $ ifconfig | grep ether ether a0:36:9f:93:7d:f8 ether a0:36:9f:93:7d:fa ether ec:f4:bb:ef:c8:e4 tcpdump confirms that the problem is in net-snmpd (and not the client). Also when using the MIB IP-MIB::ipNetToMediaPhysAddress the MAC addresses are correct. $ snmpwalk -v2c -c '***r***' localhost IP-MIB::ipNetToMediaPhysAddress | grep a0:36:9f:93:7d:f8 IP-MIB::ipNetToMediaPhysAddress.13.10.10.1.118 = STRING: a0:36:9f:93:7d:f8 I've checked net-snmpd 5.7.3 under linux and the mac addresses are correct. (So it's specific to FreeBSD.) Any clue ? Thanks, regards.
