Symptoms

Virtual address is reachable even when the virtual server is offline.

Impact

ICMP echo requests are still handled by the virtual address even though the virtual server is marked offline.

Conditions

The virtual server status is updated to offline by modifying the virtual server and adding an iRule via the GUI.

Workaround

Use tmsh to attach the iRule to the virtual server: tmsh modify ltm virtual <virtual_server_name> rules {<rule_name> }

Fix Information

None
