Disabled Tcl Commands¶
When you use the iRules feature of a BIG-IP® local traffic management
(LTM) system to create scripts for managing local network traffic, you
use the industry-standard Tool Command Language (Tcl). However, a
subset of Tcl commands are disabled on the LTM system. You should
therefore avoid using these commands when writing iRules.
