Fixed In:
13.1.1.5, 12.1.4

Opened: Dec 12, 2017
Severity: 3-Major

Symptoms

Internal packets flooded on internal switch interfaces by the HSB can be bridged back to the HSB on BIG-IP 5000/7000 and VIPRION B2100 blades configured to enable port bridging by the switch.

Impact

This can result in packet flooding back to the HSB and potential network saturation.

Conditions

-- Packets being flooded from the HSB to VLAN members when adding/deleting VLANs. -- Non-vCMP systems. -- Virtual server configured for Direct Server Return (DSR or nPath Routing).

Workaround

None.

Fix Information

Port bridging on HSB interfaces in the switch for non-vCMP systems is now disabled on BIG/IP 5000/7000. However, this issue still occurs on B2100 blades as port bridging is required on that platform for chassis data plane support.
