Fixed In:

Opened: Feb 19, 2019
Severity: 3-Major

Symptoms

The ingress and egress queues of the MRF SIP filter have fixed sizes that cannot be configured.

Impact

Messages may be dropped.

Conditions

If the hard-coded queue size of 512 messages or 65535 bytes are exceeded, the filter enables its flow control logic.

Workaround

None.

Fix Information

The max-pending-messages and max-pending-bytes values in the SIP router profile will be used as the limits for the SIP filter's queues. If the configured value is less than the existing hard-coded limits (512 bytes or 65535 bytes), the hard-coded limits will be used.
