第1步：Comware命令視圖及切換操作
<H3C>system-view
System View: return to User View with Ctrl+Z.
[H3C]quit
<H3C>system-view
System View: return to User View with Ctrl+Z.
[H3C]interface Olt3/0/1
[H3C-Olt3/0/1]quit
[H3C]vlan 10
[H3C-vlan10]quit
[H3C]ospf
[H3C-ospf-1]qu
[H3C]user-interface vty 0 4
[H3C-ui-vty0-4]return
<H3C>
system-view:從用戶視圖進入系統視圖。
quit:從當前視圖放回上一級視圖。
interface Olt3/0/1:進入接口視圖。
可以看到提示符變為[H3C-Olt3/0/1]，表示進入設備對應的接口的接口視圖，在接口視圖下，可以完成接口下各種參數的設置。
vlan 10:進入vlan視圖。
再次視圖下提示符變為[H3C-vlan10]，表示創建VLAN並進入VLAN視圖，在VLAN視圖下，可以給VLAN命名並且可以把端口加入相應的VLAN內。
ospf:進入OSPF路由協議視圖。
user-interface vty 0 4:進入VTY用戶界面視圖。
在此視圖下提示符變為[H3C-ui-vty0-4]，表示進入用戶界面視圖。在用戶界面視圖下，可以配置一系列用戶登錄的參數，如用戶登錄時是否需要認證、是否重定向到別的設備記憶用戶登錄后的權限級別等。當用戶使用該用戶信息登錄時，將收到這些參數的約束，從而達到統一管理各種用戶回話連接的目的。
return:返回用戶視圖。
第2步：使用Comware命令的幫助功能
（1） 在任意視圖下，鍵入“?”即可獲取該視圖下可以使用的所有命令及其簡單描述。
<H3C>?

<H3C>
(2)鍵入一條命令的關鍵字，后面接空格分割的“?”。如果“?”位置為關鍵字，則列出全部關鍵字及其簡單描述。
<H3C>terminal ?
debugging Send debug information to terminal
logging Send log information to terminal
monitor Send information output to current terminal
trapping Send trap information to terminal
(3)如果“?”位置為參數，則會列出有關的參數描述。
[H3C]interface Vlan-interface ?
<1-4094> VLAN interface number
[H3C]interface Vlan-interface 1 ?
<cr>
[H3C]interface Vlan-interface 1
[H3C-Vlan-interface1]
%Jun 26 19:52:30:954 2017 H3C IFNET/3/LINK_UPDOWN: Vlan-interface1 link status is UP.
%Jun 26 19:52:30:974 2017 H3C IFNET/5/LINEPROTO_UPDOWN: Line protocol on the interface Vlan-interface1 is UP.
“
(4)如果鍵入命令的不完整關鍵字，其后緊接“?”，則會顯示以該字符串開頭的所有命令關鍵字。
[H3C]f?
file
flow-classification
ftp
ftth
使用Comware命令的不完整輸入和編輯功能
<H3C>sy
System View: return to User View with Ctrl+Z.
[H3C]int O3/0/1
[H3C-Olt3/0/1]qu
[H3C]qu
<H3C>
(1)輸入sy可代替system-view的完整命令。
(2)輸入int O3/0/1可代替interface Olt3/0/1的完整命令。
(3)也可以按【Tab】鍵自動補全。
第4步：使用Comware命令的錯誤提示信息
<H3C>abc
^
% Unrecognized command found at '^' position.
<H3C>display
^
% Incomplete command found at '^' position.
<H3C>b
^
% Ambiguous command found at '^' position.
<H3C>system-view a
^
% Too many parameters found at '^' position.
<H3C>display interface Olt3/0/0/1
^
% Wrong parameter found at '^' position.
(1) % Unrecognized command found at '^' position.：表示在符號“^”指示位置的命令無法解析。
(2) % Incomplete command found at '^' position.：表示在符號“^”指示位置的命令不完整。
(3) % Ambiguous command found at '^' position.：表示在符號“^”指示位置的參數不明確。
(4) % Too many parameters found at '^' position.：表示在符號“^”指示位置輸入的參數太多。
(5) % Wrong parameter found at '^' position.：表示在符號“^”指示位置的參數錯誤。
第5步：使用Comware命令行的歷史信息
[H3C]display history-command
return
system-view
interface Vlan-interface 1
quit
system-view
return
sy
int O3/0/1
qu
system-view
第6步：使用Comware命令行的分屏顯示輸出
“---- More ----”

第7步：掌握H3C設備基本管理命令
<H3C>display clock
20:12:45 UTC Mon 06/26/2017
<H3C>clock datetime ?
TIME Specify the time (HH:MM:SS)
<H3C>clock datetime 16:36:00 ?
DATE Specify the date from 2000 to 2035 (MM/DD/YYYY or YYYY/MM/DD)
<H3C>clock datetime 16:36:00 2017/06/30
<H3C>display clock
16:36:11 UTC Fri 06/30/2017
<H3C>system-view
System View: return to User View with Ctrl+Z.
[H3C]
[H3C]sysname ?
TEXT Host name (1 to 30 characters)
[H3C]sysname H3C-R1
[H3C-R1]
(1) display clock:顯示系統當前的時間和日期。
(2) clock datetime time data:在用戶視圖下，配置時間和日期。
第8步：熟悉H3C設備的常用查看命令
