スイッチ
2021.01.16

作業環境

  • C9300 スイッチバージョン
    • バージョンアップ前：16.9.4
    • バージョンアップ後：16.12.4

バージョンアップ手順

概要

  1. OS ファイルの入手と FTP（TFTP）サーバの用意
  2. フラッシュ空き容量の確認
  3. OS ファイルのダウンロード
  4. ダウンロード後の OS ファイルの確認
  5. 新 OS のインストール
  6. バージョンアップ後の確認
  7. 旧パッケージファイルを削除

OS ファイルの入手と FTP（TFTP）サーバの用意

まず、バージョンアップ先の OS ファイルを入手し、FTP または TFTP サーバに格納します。そして FTP または TFTP サーバと対象スイッチをネットワーク接続できる環境を用意します。

対象スイッチについては FTP または TFTP サーバとネットワーク接続するための最低限のネットワーク設定を行います。

フラッシュ空き容量の確認

  • show flash:

フラッシュの空き容量が、新 OS ファイルの容量よりも大きいことを確認します。

OS ファイルのダウンロード

  • FTP の場合
    • copy ftp://<ユーザ名>:<パスワード>@<FTPサーバIP>/<OSファイル名> flash:
  • TFTP の場合
    • copy tftp://<TFTPサーバIP>/<OSファイル名> flash:
Switch#copy tftp://192.168.1.1/cat9k_iosxe.16.12.04.SPA.bin flash:
