Opened: Oct 16, 2017

Severity: 3-Major


PEM requires the DAG to be configured with key as source-ip. If this configuration is not done, the iRule PEM::session fails without a warning. In the case of lookup, the command returns an empty string


The commands fail. There is no error logged in /var/log/tmm or /var/log/ltm. No warning about misconfiguration.


-- The default tmm image (tmm.default) is running. -- The cmp-hash is not configured for SP-DAG. -- There is a query from iRule (or a session creation attempt using data-traffic).


No workaround for tmm.default.

Fix Information

There is now an error logged in /var/log/tmm or /var/log/ltm to warn about any misconfiguration.
