Release Notes:
∗
∗
Cascading of directors and switches is limited to one hop for a FICON environment.
∗
There is limited risk that Interface Control Checks (IFCCs) may be seen on the FC/IP 14+2 blade when using encryption and port channels with both
IP ports. This problem appears to be seen when only small packets are used under high stress conditions. This was not seen under z/OS.
IP ports. This problem appears to be seen when only small packets are used under high stress conditions. This was not seen under z/OS.
∗
When a zone with more than 250 members is created, there is a rare chance that all ports in a switch can fail to log in during a System z processor
Power On Reset (POR) in an FCP environment. This problem has not been seen in FICON environments. To work around this issue, customers can
bring ports up after the POR in smaller groups or use smaller zones per Cisco’s recommended best-practices for zoning.

On the MDS 9513 (only), new fabric switch modules (DS-13SLT-FAB2) are required when using the 24-port 8G FC/FICON module (DS-X9224-96K9)
or the 48-port 8G FC/FICON module (DS-X9248-96K9).

∗
Encryption on ISLs is supported on 8 Gb/sec line cards only and can not be used in Port Channel configurations.
∗
With many CHPIDs plugged into a switch, there is a limited risk of taking a few IFCCs on the CUP during CEC IML.s.
∗
8 Gb/sec optics should not be attached directly to 1 Gb/sec optics. Auto-negotiation is from 8 Gb/sec to 2 or 4 Gb/sec or from 4 Gb/sec to 1 or 2
