更新 cisco catalyst switch IOS

1. 將ios 檔案放在 tftp server

2. 登入 cisco switch
(1) 測試是否可以連上 tftp server
sw3750#ping 10.1.2.26
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.2.26, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

(2) dir 列出目前 flash 上的檔案
sw3750#dir
Directory of flash:/

2 drwx 256 Mar 1 1993 00:08:18 +00:00 c3750-ipservicesk9-mz.150-2.SE11
528 -rwx 110 Mar 1 1993 00:14:45 +00:00 info
530 -rwx 796 Mar 2 1993 04:51:48 +00:00 vlan.dat
531 -rwx 4120 Mar 1 1993 00:02:43 +00:00 multiple-fs
532 -rwx 3012 Mar 1 1993 00:02:43 +00:00 config.text
533 -rwx 3817 Mar 1 1993 00:02:43 +00:00 private-config.text

(3) 移除原來存在 flash 的檔案
sw3750#delete /f /r flash1:c3750-ipservicesk9-mz.150-2.SE11

(4) 再次確認是否已經移除
sw3750#dir
Directory of flash:/

528 -rwx 110 Mar 1 1993 00:14:45 +00:00 info
530 -rwx 796 Mar 2 1993 04:51:48 +00:00 vlan.dat
531 -rwx 4120 Mar 1 1993 00:02:43 +00:00 multiple-fs

(5) 從 tftp server 上傳ios 檔案到 switch 的 flash 上
sw3750#copy tftp flash1

Source filename []? c3750-ipbasek9-mz.122-55.SE12.bin
Destination filename [flash1]? c3750-ipbasek9-mz.122-55.SE12.bin
