MCP crashes with core. MCP automatically restarts causing other dependent daemons, including tmm, to restart. Corresponding messages (restarting mcp, restarting tmm, and so on) are broadcast in all command line connections (terminals). Core files are written into /shared/core directory. The BIG-IP system might become unusable while daemons restart, so both control-plane (tmsh/GUI) and data traffic processing are stopped until all daemons restart.
The BIG-IP system might become unusable for few minutes while daemons restart, so both control-plane (tmsh/GUI) and data traffic processing are stopped. Traffic disrupted while tmm restarts.
-- AFM is licensed and provisioned. -- There are firewall policies/rules defined in configuration. -- Remove firewall rules/policies, especially rules attached to management-IP (might have to repeat this).
None.
MCP no longer crashes, and other dependent daemons no longer restart. The BIG-IP system remains operational in both control-plane (tmsh/GUI) and data traffic processing.
