switchport port-security violation shutdown- buzilish aniqlanganda
interfeysni error-disabled holatiga o`tkazadi va o`chiradi. Undan tashqari syslog, SNMP trap, violetion counter ka`bi jurnallashtiruvchilarga xabar jo`natiladi. Ushbu holatdan chiqarish uchun shutdown va no shutdown buyruqlaridan foydalaniladi. Agar interfeysga switchport port-security violation protect buyrug`i kiritilgan bo`lsa, unda notanish MAC-manzil paketlari qabul qilinmaydi va xech qanday xabar yaratilmaydi, hamda port shutdown holatiga o`tmaydi. Ushbu usullardan switchport port-security violation restrict ko`pchilik hollarda tavsiya etiladi.
