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.
