Ps BIG-IP Interactive Shell
Problem this snippet solves:
This sample is the beginning of a full console-based management environment for your BIG-IP. Written in PowerShell, you are able to treat your BIG-IP just like your file system and navigate through, and act on, the objects in the system.
Revision History
1.0.0 - First revision. Includes initial code for gtm.wideip, ltm.pool/poolmember/virtualserver, networking.vlan, and system.systeminfo.
How to use this snippet:
Setup And Running The Script
- Save the iControlsh.ps1 file to a directory on your system.
-
Save the various modules to the following directory structure.
installdir\iControlsh.ps1 installdir\modules\gtm\wideip.ps1 installdir\modules\ltm\pool.ps1 installdir\modules\ltm\poolmember.ps1 installdir\modules\ltm\virtualserver.ps1 installdir\modules\networking\vlan.ps1 installdir\modules\system\systeminfops1
-
Run the script
installdir> .\iControlsh.ps1
-
Connect to your BIG-IP
PLEASE CONNECT> : c bigip user pass bigip> :
-
Navigate through the objects and issue some commands. At any level, type "h" for help.
