Generating Script Files

C H A P T E R 30

This chapter describes how to use Configuration Scripting to generate a text-formatted script file that shows the current configuration of the system. You can generate multiple scripts, and upload and apply them to more than one switch.

This chapter contains the following topics:

Understanding Configuration Scripting

Provides scripts that can be uploaded and downloaded to the system.

Provides flexibility to create command configuration scripts.

Can be applied to several switches.

Can save up to ten scripts or 500K of memory.

Provides List, Delete, Apply, Upload, Download.

Provides script format of one CLI command per line.

The following limitations exist:

Total number of scripts stored on the system is limited by NVRAM/FLASH size.

Application of scripts is partial if script fails. For example, if the script executes five of ten commands and the script fails, the script stops at five.

Scripts cannot be modified or deleted while being applied.

Validation of scripts checks for syntax errors only. It does not validate that the script will run.

Configuring Scripting

The following are examples of the CLI commands used for the Configuration Scripting feature.

Example 1: `script`

CODE EXAMPLE 30-1 script Command
(DTI SWITCH) # script ? apply Applies configuration script to the switch. delete Deletes a configuration script file from the switch. list Lists all configuration script files present on the switch. show Displays the contents of configuration script. validate Validate the commands of configuration script.

CODE EXAMPLE 30-1 script Command

(DTI SWITCH) 					# script ?
 
apply 	Applies configuration script to the switch.
delete	 Deletes a configuration script file from the switch.
list 	Lists all configuration script files present on the switch.
show 	Displays the contents of configuration script.
validate	 Validate the commands of configuration script.

Example 2: `script` `list` and `script` `delete`

CODE EXAMPLE 30-2 script list and script delete Commands
(DTI SWITCH) # script list Configuration Script Name Size(Bytes) ------------------------- ----------- basic.scr 93 running-config.scr 3201 2 configuration script(s) found. 1020706 bytes free. (DTI SWITCH) # script delete basic.scr Are you sure you want to delete the configuration script(s)? (y/n) y 1 configuration script(s) deleted.

CODE EXAMPLE 30-2 script list and script delete Commands

(DTI SWITCH) 					# script list
 
Configuration Script Name		Size(Bytes)
-------------------------		-----------		
basic.scr 			93
running-config.scr		 	3201		
 
2 configuration script(s) found.
1020706 bytes free.
 
(DTI SWITCH) 					# script delete basic.scr
 
Are you sure you want to delete the configuration script(s)? (y/n) y
 
1 configuration script(s) deleted.

Example 3: `script` `apply` `running-config.scr`

CODE EXAMPLE 30-3 script apply running-config.scr Command
(DTI SWITCH) # script apply running-config.scr Are you sure you want to apply the configuration script? (y/n) y The systems has unsaved changes. Would you like to save them now? (y/n) y Configuration Saved!

CODE EXAMPLE 30-3 script apply running-config.scr Command

(DTI SWITCH) 					# script apply running-config.scr
 
Are you sure you want to apply the configuration script? (y/n) y
 
The systems has unsaved changes.
Would you like to save them now? (y/n) y
 
Configuration Saved!

Example 4: `show` `running-config`

Use this command to capture the running configuration into a script.

CODE EXAMPLE 30-4 show running-config Command
(DTI SWITCH) # show running-config running-config.scr Config script created successfully. (DTI SWITCH) #script list Configuration Script Name Size(Bytes) ------------------------- ---------- running-config.scr 3201 1 configuration script(s) found. 1020799 bytes free.

CODE EXAMPLE 30-4 show running-config Command

(DTI SWITCH) 					# show running-config running-config.scr
 
Config script created successfully.
 
(DTI SWITCH) 					#script list
 
Configuration Script Name		Size(Bytes)
-------------------------		----------
running-config.scr		3201
 
1 configuration script(s) found.
1020799 bytes free.

Example 5: `copy` `nvram:` `script`

Use this command to upload a configuration script.

CODE EXAMPLE 30-5 copy nvram: script Command
(DTI SWITCH) # copy nvram: script running-config.scr tftp://192.168.77.52/running-config.scr Mode......................... TFTP Set TFTP Server IP........... 192.168.77.52 TFTP Path.................... ./ TFTP Filename................ running-config.scr Data Type.................... Config Script Source Filename.............. running-config.scr Are you sure you want to start? (y/n) y File transfer operation completed successfully.

CODE EXAMPLE 30-5 copy nvram: script Command

(DTI SWITCH) 					# copy nvram: script running-config.scr
tftp://192.168.77.52/running-config.scr
 
Mode.........................			TFTP
Set TFTP Server IP...........		192.168.77.52
TFTP Path....................		./
TFTP Filename................		running-config.scr
Data Type....................		Config Script
Source Filename..............		running-config.scr
 
Are you sure you want to start? (y/n) y
 
File transfer operation completed successfully.

Example 6: `script validate running-config.scr`

CODE EXAMPLE 30-6 script validate running-config.scr Command
(DTI SWITCH) # script validate running-config.scr serviceport protocol none network protocol dhcp no network javamode vlan database exit configure logging buffered logging host 192.168.77.151 Configuration script ‘running-config.scr’ validated. (DTI SWITCH) # script apply running-config.scr Are you sure you want to apply the configuration script? (y/n) y The system has unsaved changes. Would you like to save them now? (y/n) y Configuration Saved!

CODE EXAMPLE 30-6 script validate running-config.scr Command

(DTI SWITCH) 					# script validate running-config.scr
serviceport protocol none
network protocol dhcp
no network javamode

Configuration script ‘running-config.scr’ validated.
 
(DTI SWITCH) 					# script apply running-config.scr
 
Are you sure you want to apply the configuration script? (y/n) y
The system has unsaved changes.
Would you like to save them now? (y/n) y
Configuration Saved!

Example 7: Validate Another Configuration Script

CODE EXAMPLE 30-7 script validate default.scr Command
(DTI SWITCH) # script validate default.scrnetwork parms 172.30.4.2 255.255.255.0 0.0.0.0vlan databaseexitconfigurelineconfigexitspanning-tree configuration name 00-18-00-00-00-10interface 0/1exitinterface 0/2exitinterface 0/3exit... continues through interface 0/26 ...exitexitConfiguration script 'default.scr' validation succeeded.
