Juniper: JUNOS export and domestic version

今日有個client 問我點解佢upgrade完 Juniper Router, 之後佢連唔番隻Router (SSH), 然後我問佢你用緊乜version firmware, 佢答我用緊export version.

其實Juniper 某幾類Router要用domestic version才可以使用SSH. By deafult, 係佢官網download的是export version (worldwide), 你要選擇US/Caanda 才是domestic version.

各位, 如果你要做remote upgrade時, 真是要睇清楚firmware version 會不會支援番你用緊mgmt protocol, 一出錯你就要落現場救機了.
