Symptoms

tmsh allows configuration of a virtual server with mismatched ip-protocol and transport-layer profile. For example, ip-protocol tcp with a UDP profile or ip-protocol udp with a TCP profile, or ip-protocol any with a TCP profile.

Impact

Traffic reaching a misconfigured virtual server can crash tmm, resulting in an outage.

Conditions

Configure a virtual server with mismatched ip-protocol and transport-layer profiles (e.g., ip-protocol udp, profiles { tcp }).

Workaround

Configure virtual server with matching ip-protocol and transport-layer profile.

Fix Information

Validation for both TCP and UDP profiles has been updated to correctly require the profile type and protocol type to match.
