This read-write value enables or disables port security violation traps across all ports on the switch simultaneously, though this object always reads back as disable regardless of the last value written. An admin uses this to switch on violation alerting switch-wide in a single operation rather than configuring agentPortSecurityViolationTrapMode on each port individually. For example, writing enable(1) here would activate violation traps on every locked port at once, even though a GET on this object afterward would still return disable(2).
