第1步：Comware命令视图及切换操作
<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:从用户视图进入系统视图。
quit:从当前视图放回上一级视图。
interface Olt3/0/1:进入接口视图。
可以看到提示符变为[H3C-Olt3/0/1]，表示进入设备对应的接口的接口视图，在接口视图下，可以完成接口下各种参数的设置。
vlan 10:进入vlan视图。
再次视图下提示符变为[H3C-vlan10]，表示创建VLAN并进入VLAN视图，在VLAN视图下，可以给VLAN命名并且可以把端口加入相应的VLAN内。
ospf:进入OSPF路由协议视图。
user-interface vty 0 4:进入VTY用户界面视图。
在此视图下提示符变为[H3C-ui-vty0-4]，表示进入用户界面视图。在用户界面视图下，可以配置一系列用户登录的参数，如用户登录时是否需要认证、是否重定向到别的设备记忆用户登录后的权限级别等。当用户使用该用户信息登录时，将收到这些参数的约束，从而达到统一管理各种用户回话连接的目的。
return:返回用户视图。
第2步：使用Comware命令的帮助功能
（1） 在任意视图下，键入“?”即可获取该视图下可以使用的所有命令及其简单描述。
<H3C>?
User view commands:

terminal Set the terminal line characteristics
tftp Open TFTP connection
tracert Trace route function
umount Umount a device
undelete Recover a deleted file
undo Cancel current setting
<H3C>
(2)键入一条命令的关键字，后面接空格分割的“?”。如果“?”位置为关键字，则列出全部关键字及其简单描述。
<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“?”位置为参数，则会列出有关的参数描述。
[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)如果键入命令的不完整关键字，其后紧接“?”，则会显示以该字符串开头的所有命令关键字。
[H3C]f?
file
flow-classification
ftp
ftth
使用Comware命令的不完整输入和编辑功能
<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)输入sy可代替system-view的完整命令。
(2)输入int O3/0/1可代替interface Olt3/0/1的完整命令。
(3)也可以按【Tab】键自动补全。
第4步：使用Comware命令的错误提示信息
<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.：表示在符号“^”指示位置的命令无法解析。
(2) % Incomplete command found at '^' position.：表示在符号“^”指示位置的命令不完整。
(3) % Ambiguous command found at '^' position.：表示在符号“^”指示位置的参数不明确。
(4) % Too many parameters found at '^' position.：表示在符号“^”指示位置输入的参数太多。
(5) % Wrong parameter found at '^' position.：表示在符号“^”指示位置的参数错误。
第5步：使用Comware命令行的历史信息
[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命令行的分屏显示输出
“---- More ----”
……
第7步：掌握H3C设备基本管理命令
<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:显示系统当前的时间和日期。
(2) clock datetime time data:在用户视图下，配置时间和日期。
第8步：熟悉H3C设备的常用查看命令
