JUNOS_RTG
JuniperのRTG検証。
RTGはCiscoでいうところのFlex-Link機能
↑で検証
EX2200-24T-4G側のAE0をプライマリ、AE1をセカンダリとして検証

JUNOS_EXシリーズ初期化
最近、学習用でJuniper EXシリーズのSwitchを購入
暫くはこれで勉強予定。
んで、起動時に以下のメッセージがでる。
***********************************************************************
** **
** WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE **
** **
** It is possible that the primary copy of JUNOS failed to boot up **
** properly, and so this device has booted from the backup copy. **
** **
** Please re-install JUNOS to recover the primary copy in case **
** it has been corrupted and if auto-snapshot feature is not **
** enabled. **

***********************************************************************
ようは、PrimaryからBootしていないというメッセージ。
多分、request system haltをせずに電源ケーブルを抜いたんだろう・・・
とりあえず、リカバリー
