Cisco Catalyst kommutatorlarida parolni olib tashlash (сброс)
Cisco Catalyst kommutatorlarida parolni olib tashlash uchun qurilmaga fizik kirish imkoniyati kerak.
Kommutatorga konsol kabeli orqali ulaniladi, tok energiyasi manbasidan o`chiriladi va qayta ishga tushiriladi, ishga tushirilish vaqtida oldi panelidagi “MODE” tugmasi bosib turiladi (3.4-rasm.).

3.4-rasm. “MODE” tugmasining kommutatorda joylashish o`rni.
Shu tarzda odatiy ishga tushish to`xtatiladi.

Bundan keyin flash_init va load_helper buyruqlari kiritiladi va dir flash buyrug`ini foydalanish orqali flash xotiraning tarkibini ko`rish imkoniyati paydo bo`ladi.

Yuqoridagi flash xotiraning tarkibidan config.text, ya`ni kommutatorning konfiguratsion fayli ko`rib chiqiladi. Kommutator config.text konfiguratsion faylisiz ishga tushirilishi uchun nomi o`zgartiriladi. Bu rename flash:config.text flash:config.old buyrug`i bilan amalga oshiriladi va tekshiriladi

Bundan keyin, ishga tushishni boot buyrug`i orqali tiklaymiz.
switch: boot
Kommutator konfiguratsiya faylini topa olmaydi va usiz ishga tushadi. Endi imtiyozli rejimga kiriladi va konfiguratsiya fayli nomi qayta o`z nomiga rename flash:config.old flash:config.text buyrug`i orqali o`zgartiriladi va copy flash:config.text system:running-config buyrug`i orqali u ishga tushiriladi.
