きのしのきょう

10GbE SFP+ Uplink Moduleが届きました！1ヶ月前ぐらいに手に入れたJuniper Networks EX4200-24T用の、EX-UM2X4SFPってやつです。

初の10GbE体験だー、と喜びうかれて、さくさくインストール。すると、何かがおかしい…

root@EX4200> show interfaces ge-0/0/0
error: device ge-0/0/0 not found

あれぇ、何で内蔵ポートまで見えなくなってるの？

root@EX4200> show chassis hardware
error: the chassis-control subsystem is not running

え、なにごと…？

と思ってdmesgを見てみると、

in_ifalrequest: .local. op 5 local 0/0

えええーーー！マジデスカ？

で、ここにきて初めてドキュメントをきちんと読んでみると、

The SFP+ uplink module requires JUNOS Software for EX Series switches, Release 9.4 or later.

うちのスイッチのJUNOSは9.2やねん…

というわけで、私の10GbE体験はしばらくお預けになってしまいましたとさ。
