We have all ports with maclock protection with no dynamic entries and violation enable.
All day we have violations with invalid mac addresses detected by switch.
Macs like 00:00:00:10:12:00. or AB:00:AB:00:11:11 and many others that doesnt have a valid vendor.
What causes this violations? virus? malware? cable?
can be a switch problem? negotiation?
How can switch port detects these macs?
Switchs Enterasys B5.
Tks for help.
