Explanation

Job is a segment script , it defines command group ,and can set job when to carry outor interval of execution.

Example

The following example defines to shutdown of all jobs on the port:

job shutall int s1/0;shut;int s1/1;shut;int s1/2;shut;int s1/3;shut

The following example defines not to shutdown all jobs on the port:

job noshutall int s1/0; no shut;int s1/1;no shut;int s01/2;no shut;int s1/3;no shut

The following example defines to periodically execute shutdown and no shutdownoperation on all ports:job schedule shutall at 100 interval 60

job schedule noshutall at 130 interval 60

(Then, after the jobd starts for 100 seconds, shutall this job starts, restarts every 60seconds; after the switch starts for 130 seconds, noshutall shutall this job starts,restarts every 60 seconds.)

If you want to execute the sequence of shutall and noshutall, you can define andschedule as follows:job reshut job exec shutalljob exec noshutall

job schedule reshut at 100 interval 30

If shutall error during execution, execute the next command(pause by default)job shutall on-error next

If executes noshutall:(no recursion of the job)job shutall on-error exec noshutall

The following example, pause a jobjob stop shutall

Chapter 2 Terminal Service Command

2.1 Telnet Configuration Command

This chapter will introduce telnet and its configurations and management commands.telnet is used to setup telnet session with a remote server. telnet is usually used totelnet Unix system.

It needs negotiation about optional items. telnet can not provide authorization to itself .So , it is mostly different from Rlogin in which it can not provide password verificationto itself.

Telnet configuration command is following:

telnet

ip telnet

where

disconnect

resume

switchkey

switchmsg

sequence-char

clear Telnet

show Telnet

debug Telnet

2.1.1 telnet

Syntas

telnetserver-ip-addr/server-host-name[/portport][/source-interfaceinterface] [/locallocal-ip-addr] [/debug][echo/noecho] [/scriptscriptname]

Parameter


server-ip-addr Remote servers IP address is expressed by decimal system.


37/128


- 32 -

server-host-name:The host name of the remote server, it need use command ip host to

configure.

port The port providing telnet service of the remote server.

interface: Local interface to launch telnet connection

local-ip-addr Local IP address to launch telnet connection.

debug Open debug switch of client , print negotiation course when connection.

echo/noecho Open/turnoff local echo, default is noecho.

scriptname The script name used to automatically login.

Default

port default is 23, interface does not have default.

Command mode

supervisor mode

Explanation

User can use one of following commands to telnet

telnet server-ip-addr/server-host-name

In this condition, application program will transmit telnet request to 23 interface of the

remote server, the used IP address is the nearnest IP address according to route table.

telnet server-ip-addr/server-host-name /port port

At this time, application program transmit telnet request to the peer port.

telnet server-ip-addr/server-host-name /source-interface interface

At this time, application use interfaces IP address as local address.

telnet server-ip-addr/server-host-name /debug

At this time, application program opens debug switch of client, and will output linknegotiation course.

telnet server-ip-addr/server-host-name echo/noecho

At this time , application program opens/closes local echo. Usually, Local echo isclosed ,echo is finished by the server. Only when the server is not responsible for echo,local echo switch will open.

telnet server-ip-addr/server-host-name /script scriptname

Before execute automatically login command of this script , use command ip telnetscript to configure.


38/128


- 33 -

Above command parameters can be used united.

When in the course of session with the remote server ,user can use q key to quit .Ifdo not exit by hand, it will exit after 10 seconds waiting.

Example

1.If user want to telnet to the server 192.168.20.124, and the server has two telnetports: 23 and 2323, and local has two ports: e1/1(192.168.20.240) ands1/0(202.96.124.240).User can use following commands to telnet.

telnet 192.168.20.124 /port 2323

2.In such a condition , telnet will connect to peer 2323 port .The local IP address seenby the peer is 192.168.20.240.

telnet 192.168.20.124 /source-interface s1/0

3.In such a condition, telnet will connect to peer 23 port .The local IP address seen bythe peer is 202.96.124.240.

telnet 192.168.20.124 /local 192.168.20.240

4.In such a condition , telnet will connect to peer 23 port .The local IP address seen bythe peer is 192.168.20.240.

telnet 192.168.20.124 /debug

5.In such a condition, telnet will print negotiation course to setup telnet connection topeer 23 port.

telnet 192.168.20.124 /echo

6.In such a condition, telnet will open local echo switch. At his time, if the sever runsecho also, all input will be echoed for two times.

telnet 192.168.20.124 /script s1

7.Use login script named s1 to automatically login.

Command mode


Explanation

User can use following commands to configure local source interface to launchtelnet.

ip telnet source-interface interface

In such a condition, all subsequent telnet use this interface. This configurationcommand is similar to telnet source-interface interface, but it does not need toadd parameter when using command telnet. If not only configure ainterface ,but also add interface parameter in command telnet, it should bedetermined by the latter.

User can use following commands to configure access list names limited bylocal telnet connection.

ip telnet access-class accesslist

In such a condition, after that, when the server accepts all telnet connections, itneeds to check access list.

User can use following commands to configure other interfaces except default(23) to receive telnet connection.

ip telnet listen-portstart-port [end-port]

Explanation: if not appoint end-port number, it will intercept on a special port.The numbers of appointed interception ports can not be more than 16,and portscan be limited between 3001 and 3999.

User can use the following commands to configure telnet login script.

ip telnet script s1 login: switch Password: test

Explanation: when configuring script , user name prompt, answer, passwordprompt ,answer must fully match. And user must pay attention to prompt

information, it differs whether capitalization or not, and prompt information must

add (). If any item is not configured properly, it can not automatically loginsuccessfully .

Note :

Above four commands can add prefix no to cancel setting.

Example

1.In such a condition, all coming launching telnet connections use s1/0 interface.

ip telnet source-interface s1/0

2.In such a condition, all coming accepting telnet connections will be checked byaccess-list abc.

ip telnet access-class abc

3.Besides 23,user can use all port between 3001 and 3010 to accept telnetconnections.

ip telnet listen-port 3001 3010

4.configure a login script named s1,user name prompt is login:, answer is switch,password prompt is Password:, answer is test.
