Ethernet interfeyslari
Ethernet interfeyslari tizim tomonidan taxmin qilinadigan tarmoq interfeysi nomlari yordamida aniqlanadi. Ushbu nomlar eno1 yoki enp0s25 sifatida ko'rinishi mumkin. Biroq, ba'zi hollarda interfeys hali ham nomlash uslubi yadrosidan foydalanishi mumkin.
Ethernet interfeyslarini aniqlash
Mavjud barcha chekilgan interfeyslarni tezda aniqlash uchun siz ip buyrug'idan quyida ko'rsatilgandek foydalanishingiz mumkin.

ip a
1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Tizimingiz uchun mavjud bo'lgan barcha tarmoq interfeyslarini aniqlashga yordam beradigan yana bir dastur bu lshw buyrug'idir. Ushbu buyruq ma'lum adapterlarning apparat imkoniyatlari atrofida batafsilroq ma'lumot beradi. Quyidagi misolda lshw bitta chekilgan interfeysni et0 mantiqiy nomi bilan, shinalar haqida ma'lumot, haydovchi tafsilotlari va barcha qo'llab-quvvatlanadigan imkoniyatlarni ko'rsatadi.

Ethernet interfeysi mantiqiy nomlari
Interfeysning mantiqiy nomlari netplan konfiguratsiyasi orqali ham sozlanishi mumkin. Agar siz qaysi interfeysning ma'lum bir mantiqiy nomni qabul qilishini xohlasangiz, mos keladigan va o'rnatilgan ism tugmalaridan foydalaning. Match-manzil, drayver va hk kabi ba'zi bir mezonlarga asoslangan adapterni topish uchun mos klavishadan foydalaniladi, so'ngra o'rnatilgan nom tugmachasi yordamida qurilmani kerakli mantiqiy nomga almashtirish mumkin.

Ethernet interfeysi sozlamalari

ethtool - bu avtomatik muzokara, port tezligi, dupleks rejim va LAN-da uyg'onish kabi chekilgan karta sozlamalarini aks ettiradigan va o'zgartiradigan dastur. Quyida Ethernet interfeysining qo'llab-quvvatlanadigan xususiyatlarini va sozlangan sozlamalarini qanday ko'rish mumkinligi haqida misol keltirilgan.
