When updating an iRule via tmsh, if the iRule uses the 'recv' command, saving the iRule causes tmsh to display an incorrect warning, e.g.: warning: [variable reference used where variable name expected][$conn_id] The same warning may be seen if loading the configuration via tmsh. Note: This warning is generated by the control plane (when loading/modifying an iRule), and does not occur when TMM executes an iRule.
Modifying the iRule as suggested by the warning results in run-time TCL exceptions, and may cause traffic through affected virtual servers to fail to flow.
iRule that uses the 'recv' command.
Ignore the warning.
tmsh will no longer display an incorrect warning when validating an iRule that uses the recv command.
