Affected Product(s):
BIG-IP F5OS-C
Fixed In:
17.1.1.2
Opened: Jan 02, 2024 Severity: 2-Critical
When the traffic is high, an overloaded blade can disconnect from the BIG-IP cluster due to dropped internal heartbeat packets.
Blades can disconnect from the BIG-IP cluster.
Issue can be triggered when there is high and sustained traffic loads.
Decrease the traffic level until the blade rejoins the cluster.
Priority of CDP packets are increased, so that they use high priority queues and are protected against being dropped when the front panel traffic load is high. Also optimized the algorithm that determines cross-blade disaggregation state to improve recovery when a blade drops out and rejoins a cluster.
