Catalyst2950 IOSバージョン変更【バージョンアップ・ダウングレード】

備忘録として

ちょっと検証が必要となったので、久しぶりにciscoのIOSを変更した。

Catalyst2950(古!)

せっかくなので、備忘録も兼ねて、ブログに掲載しておく。

今回は、『c2950-i6k2l2q4-mz.121-22.EA13.bin』から『c2950-i6q4l2-mz.121-22.EA2.bin』へのダウングレード(これも古!)

バージョンアップもやり方は同じ。

TFTPサーバのIPアドレスは192.168.0.1/24

TFTPサーバはTFTPDを使用した。

前提として、IPアドレスを割り当てておく(今回はデフォのVLANに192.168.0.10/24を割り当てた)

Switch#conf t
Switch(config)#interface vlan 1 ← デフォのVLAN
Switch(config-if)#ip address 192.168.0.10 255.255.255.0
Switch(config-if)#no shutdown

  1. メモリ内の確認
    Switch#dir flash:/
    Directory of flash:/2 -rwx 3721946 Mar 01 1993 09:03:48 +09:00 c2950-i6k2l2q4-mz.121-22.EA13.bin
    3 -rwx 44 Mar 01 1993 10:41:58 +09:00 private-config.text
    4 -rwx 1048 Mar 01 1993 10:41:58 +09:00 multiple-fs
    6 -rwx 5055 Mar 01 1993 10:41:58 +09:00 config.text
    7 -rwx 976 Mar 01 1993 09:00:23 +09:00 vlan.dat7741440 bytes total (4009984 bytes free)
  2. TFTPサーバからダウンロード
    Switch#copy tftp flash:
    Address or name of remote host []? 192.168.0.1 ← TFTPサーバのIPアドレス
    Source filename []? c2950-i6q4l2-mz.121-22.EA2.bin ← ブートイメージ名
    Destination filename [c2950-i6q4l2-mz.121-22.EA2.bin]?
    Accessing tftp://210.155.246.36/c2950-i6q4l2-mz.121-22.EA2.bin…

  3. ブートイメージ(c2950-i6q4l2-mz.121-22.EA2.bin)がメモリに格納されたことを確認
    Switch#dir flash:/
    Directory of flash:/2 -rwx 3721946 Mar 01 1993 09:03:48 +09:00 c2950-i6k2l2q4-mz.121-22.EA13.bin
    3 -rwx 44 Mar 01 1993 10:41:58 +09:00 private-config.text
    4 -rwx 1048 Mar 01 1993 10:41:58 +09:00 multiple-fs
    5 -rwx 3086328 Mar 01 1993 09:27:09 +09:00 c2950-i6q4l2-mz.121-22.EA2.bin
    6 -rwx 5055 Mar 01 1993 10:41:58 +09:00 config.text
    7 -rwx 976 Mar 01 1993 09:00:23 +09:00 vlan.dat7741440 bytes total (923648 bytes free)
  4. 起動時のブートイメージの変更
    Switch#conf t
    Switch(config)#boot system flash:c2950-i6q4l2-mz.121-22.EA2.bin
  5. リロードして確認
    Switch#reload
    再起動されたら
    Switch#show version
