Information

 
TitleFDB entry not added on slot X. Hardware Table full.
Symptoms
BD8K experiences flooding
MACs not added to FDB 
Warning messages will be logged:
<Warn:HAL.FDB.L2SlotTblFull> MSM-A: FDB entry not added on slot 4. Hardware Table full. 
Environment
Platform: BD8K
Specific hardware: c-series IO Cards
Firmware: 15.6.4.2
Cause
Dual-hashing was not enabled in firmware for BD8K c-series cards therefore this option was not available to configure on those cards and hashing is worse.
Resolution
There is a new CR created as the fix for CR xos0064579 is not good.
 A new CR, xos0065937, is created which will fix dual hashing.
For now this is scoped for 16.1.5 and 16.2.3.

A workaround could be changing the hashing to crc16 until a fix is ready.
configure forwarding hash-algorithm crc16
