====== IX2215のファームウェアを更新する ======

===== 試した環境 =====

  * UNIVERGE IX2215
    * IPアドレス：192.168.1.3
    * USBシリアル接続
  * TFTPD64 v4.64 (Windows 10 Pro. x64)
    * IPアドレス：192.168.1.2

===== 手順 =====

TFTPD64の設定は割愛。フォルダにファームウェアを放り込んでtftpd64.exeを起動するだけなので、何も難しいことはないだろうけど…

==== 既存のファームウェアのバックアップ ====

念のためIX2215に最初から入っているファームウェアをバックアップしておく。

既存のファームウェアの確認。

<code>
Router# config
Router(config)# show flash
Codes: M - Main-side, B - Backup-side, N - Newfile, R - Runnable
       A - Active-file, + - Next-boot, * - Bootmode-entry
Length     Name                          Status
4977665    ix2215-ms-8.10.11.b.ldc       MA

</code>

GE2にIPアドレスを振る。
<code>
Router(config)# interface GigaEther2.0
Router(config-GigaEther2.0)# ip address dhcp receive-default
Router(config-GigaEther2.0)# no shutdown
Router(config-GigaEthernet2.0)# show ip address
Interface GigaEthernet2.0 is up, line protocol is up
  Internet address is 192.168.1.3/24
  Broadcast address is 255.255.255.255
  Address determined by DHCP
  Primary DNS server is 192.168.1.1
</code>

TFTPサーバにファームウェアをアップロードする。
<code>
Rounter(config-GigaEther2.0)# exit
Router(config)# tftp put ix2215-ms-8.10.11.b.ldc 192.168.1.2:ix2215-ms-8.10.11.b.ldc

</code>

==== ファームウェアの更新 ====

<code>
Router(config)# software-update tftp://192.168.1.2/ix2215-boot-22.1-gate-ms-10.7.18.rap

念のため内蔵フラッシュの状態を確認。

<code>
Router(config)# show flash
Codes: M - Main-side, B - Backup-side, N - Newfile, R - Runnable
       A - Active-file, + - Next-boot, * - Bootmode-entry
Length     Name                          Status

8991293    ix2215-ms-10.7.18.ldc         N+

ルータを再起動
<code>
Router(config)# reload
% Warning: current running-configuration is not saved yet.
Notice: The router will be RELOADED. This is to ensure that
        the peripheral devices are properly initialized.
Are you sure you want to reload the router? (Yes or [No]): yes
