To monitor the MAC addresses that are learned and stored in the CAM table, to specify the polling
interval for the CAM table, or to specify the upper and lower limits for the learning of MAC addresses,
use the set cam monitor command.
set cam monitor {enable | disable} [mod/port | vlan]
set cam monitor interval time_s
set cam monitor high-threshold value [action {no-learn | shutdown | warning}]
{mod/port | vlan}
set cam monitor low-threshold value [action {no-learn | warning}] {mod/port | vlan}
