If a virtual server is using a traffic-matching-criteria (TMC) with a destination-inline-port of zero ('any'), and this is later changed (either to a non-zero port value, or to a port-list with non-zero port values) the virtual server stops processing traffic. If tmm is restarted (which causes an outage) the virtual server resumes accepting traffic using the new ports. In addition, changing the virtual server's port back to 'any' also causes traffic processing to resume.
The virtual server stops processing traffic.
-- A virtual server using an address list for its destination, and 'any' (zero) for its destination port. -- Changing the virtual server's destination port to a non-zero value, or to a port-list with non-zero port values.
To recover, you can do either of the following: -- Restart tmm: bigstart restart tmm -- Change the virtual server's port back to 'any' (0).
