Affected Product(s):
F5OS Velos
Fixed In:
F5OS-C 1.8.0
Opened: Nov 21, 2023 Severity: 3-Major
In VELOS v1.7.1, the system controller relies on the slot width of each blade in order to configure the backplane portfor the blade. When the slot width is set to "1", the system controller configures for Bx110. If it is set to "2", system controller configures the BX520 blade. If the ConfD slot info is not available, the resulting backplane port configuration may be unsuitable for the blade occupying the given slot.
Blade will fail to send /receive traffic over the backplane.
A Bx110 or Bx520 blade is present in the chassis.
None
Blade backplane port link errors no longer observed when suitable slot info is present in system controller ConfD.
