Simple basic setup of SONiC OS for swicth Celestica Seastone DX010, 32-port 100G in L2 mode, and simple ACL restriction for SSH managemnt.

In continuing to Hardware switch with stateless firewall rules. Seastone DX010. SONiC OS, SONiC Notebook.

Conditions. Two Celestica DX010 switches (Celestica1, Celestica2) are connected via a 100G (4x25G) uplink connection located in different data centres.

Task. Manage the settings of the Celestica2 from the console of the Celestica1 switch, but not vice versa.

Hardware switch with stateless firewall rules. Seastone DX010. SONiC OS.

⌛ Нові часи швидкостей 📶 і нове обладнання приходиться опановувати.

Так опановую налаштування 100Gb обладнання 🔨 на прикладі "Celestica Seastone DX010, 32-Port 100G QSFP28 Onie Switch" з операційною системою SONiC OS.

🚆 Великі швидкості передачі - великі вимоги до часу ⛳ обробки мережевих пакетів. Для пришвидшення обробки використовуються спеціальні апаратні акселератори (ASIC), наприклад,  Broadcom Tomahawk ASIC.

🚀 ASIC своєю чергою можуть мати свої обмеження 🚧, такі, наприклад як stateless firewall правила в ACL
