For many years our C5 stacks (edge switches) have the following configuration for all edge ports...
set maclock enable
set maclock trap enable violation
set maclock agefirstarrival enable
set maclock firstarrival 8
set maclock enable
This was recommended by an Enterasys Engineer to protect the network from loops, mac floods and notify us if a port has more than 8 devices (we use macauth/multiauth; C5 limit is 8 devices).
Over the years the system has worked well except for once in a while (due to a firmware bug) the maclock firstarrival # needs to be increased for a total of 8 devices to be allowed (only happens when switch has been running for months and a reboot fixes things).
When I run "show maclock" I see...
Port Port Trap Syslog Aging Port Clr Max Max Last Violating Number Stat Thr|Viol Thr|Viol Stat Dis|Viol OLC Stc FA MAC Address -------- ---- -------- -------- ---- -------- --- --- ---- -----------------
ge.2.37 ena dis|ena dis|dis ena dis|dis ena 20 8 c0:3f:d5:f6:23:73
Short of rebooting the switch, how do I clear the "Last Violating Mac Address"?
Have tried Policy Manager's Maclock tab; when I select an entry, the "Remove" button remains greyed out.
