8.搜索输出信息
搜索和操作屏幕信息，下面是一些常用快捷键
Keyboard Sequences for Searching and Manipulating On-screen Data
Function Keyboard Sequence
List the keyboard sequences available when the -(more)- prompt is displayed h
Display output all at once (like no-more option) N
Repeat previous search for a string n
Search for a text string (like match option) m or M
Search, ignoring a text string (like except option) e or E
Do not redisplay prompt after displaying the output (like hold option) H
Clear match conditions and display complete output c or C
Save output to a file (like save option) s or S
Scroll down one line Enter, k, Ctrl-m, Ctrl-n, down arrow
Scroll down a half screen Tab, d, Ctrl-d, Ctrl-x
Scroll down whole screen Space, Ctrl-f
Scroll down to bottom of output Ctrl-e, G
Display previous line output j, Ctrl-h, Ctrl-p, up arrow
Scroll up a half screen u, Ctrl-u
Scroll up a whole screen b, Ctrl-b
Scroll to top of screen g, Ctrl-a
Search forward /string
Search backward ?string
/参数可以非常有用的帮助我们搜索文件。输入 / 参数，然后输入字符串。

root@52network> show configuration
version 5.0R2.4;
system {
host-name 52network;
login {
class superuser {
permissions all;
}
user root {
uid 2000;
class superuser;
authentication {
encrypted-password "lGdV/"; # SECRET-DATA
Search for: bgp
bgp {
traceoptions {

USER TTY FROM LOGIN@ IDLE WHAT
root d0 - 8:03AM - CLI
lab p0 192.168.161.10 7:55AM 2 /bin/csh
13.cli帮助信息：
root@52network> help ?
Possible completions:

下面帮助信息告诉你如何配置多播源发现协议(msdp)
root@52network> help topic msdp group
Configure MSDP Groups
An MSDP router must know which routers are its peers (neighbors). You define
the peer relationships explicitly by configuring the neighboring routers that
are the MSDP peers of the local router. After peer relationships are
established, the MSDP peers exchange messages to advertise active multicast
sources. You can arrange peers into different groups. Each group must contain
at least one peer. Arranging peers into groups is useful if you want to block
sources from some peers and accept them from others or set tracing options on
one group and not the others.
To configure MSDP groups, include one or more of the following statements at
the [edit protocols msdp group group-name] hierarchy level:
[edit protocols msdp]
group group-name {
disable;
export [ policy-name ];
import [ policy-name ];
local-address address;
mode <(mesh-group | standard)>;
traceoptions {
file name <replace> <size size> <files number> <no-stamp>
<(world-readable | no-world-readable)>;
traceflag flag <flag-modifier> <disable>;
}
peer address; {
disable;
export [ policy-name ];
import [ policy-name ];
local-address address;
traceoptions {
file name <replace> <size size> <files number>
<no-stamp>
<(world-readable | no-world-readable)>;
flag flag <flag-modifier> <disable>;
}
}
The individual statements are discussed in separate sections.

ription
Define an MSDP peer group. MSDP peers within groups share common
traceoptions, if present and not overridden for an individual
peer with the peer statement. To configure multiple MSDP groups, include multiple group
statements.
By default, the group's options are identical to the global MSDP options.
To override the global options, include group-specific options within the
group statement.
The group must contain at least one peer.
