The maximum number (N) of MAC addresses to be
secured on the interface. The first N MAC
addresses learned or configured are made secured.
Changing this object value from N to M is not
allowed if M is smaller than N, and M is less
than the value of cpsIfCurrentSecureMacAddrCount
on the interface. One way to change the number in
this case is by deleting sufficient number of
secure mac addresses configured or learned on the
device. Also, sum of this object value for all the
interfaces is less than or equal to
cpsGlobalMaxSecureAddress.
