What is tmnxDhcpSvrStatsDropInvalidUsr?
Counts DHCP packets dropped because the sender's MAC address or option 82 content didn't match the host's existing lease state. Operators investigate this when it grows, since it can indicate a spoofed client or a device that changed NICs without releasing its old lease.
Examples
