Concern for Avaya (Nortel) ERS 8600 Chassis users: Two recent software versions, namely v5.1.4 and v5.1.5, contain a potential service impacting issue.
Please do not upgrade to one of these versions, but use the fixed software version v5.1.5.1 instead.
Fixed issue:
A datapath issue has been identified that may impact the ability to learn MAC addresses and forward packets for which the source MAC address is unknown. This will only happen if the traffic enters the same LANE as the IST is located on and if the IST occupies the first port in the LANE. Also, this is only seen on card types 8630GBR, 8648GBRS, 8634XGRS and 8612XLRS. (wi00866354)
