We have a RackSwitch G8052 switch, I already executed the snmpwalk command
(I saw it in the sumavi.com guide of xCat). I have this output:
# snmpwalk -v 1 -c public switch1 .1.3.6.1.2.1.31.1.1.1.1 | head
IF-MIB::ifName.1 = STRING: IP1
IF-MIB::ifName.129 = STRING: Ethernet1
IF-MIB::ifName.130 = STRING: Ethernet2
IF-MIB::ifName.131 = STRING: Ethernet3
IF-MIB::ifName.132 = STRING: Ethernet4
IF-MIB::ifName.133 = STRING: Ethernet5
IF-MIB::ifName.134 = STRING: Ethernet6
Now, I tested with both switchport=3, and swithport=Ethernet3 and always
run the discovery kernel until:
Network configuration complete, commencing transmit of discovery packets
But no mac is added to node definition (e.g: lsdef node3).
Maybe it has nothing to do, but... is it neccesary to have IPv6? (I
disabled it using sumavi web advice)
Thanks a lot, and sorry for bother you with questions.
