Error reporting
Non-implicit link incidents (such as Fabric OS recognized or bit error rate threshold exceeded) and
implicit link incidents (such as FRU failure) are reported to registered listeners on the local switch. The
RMF 74-7 record (FICON Director Activity Report, which is the same RMF record containing the
average frame pacing delay information) reports port errors, which in turn are also reported back to the
mainframe host management consoles.
Secure access control
Binding is a method used to prevent devices from attaching to the switch or backbone. Secure Access
Control Lists (ACLs) provides the following fabric, switch, and port binding features:
• Fabric binding is a security method for restricting switches within a multiple-switch fabric. Brocade
recommends using fabric binding for cascaded FICON. SCC ACLs with strict fabric-wide
consistency are required for FICON fabric binding.
• Switch binding is a security method for restricting devices that connect to a particular switch or
backbone. If the device is another switch, this is handled by the SCC policy. If the device is a host
or storage device, the device connection control (DCC) policy binds those devices to a particular
switch. Policies range from completely restrictive to reasonably flexible, based upon customer
needs. SCC ACLs with strict fabric-wide consistency are necessary for FICON switch binding.
• Port binding is a security method for restricting host or storage devices that connect to particular
switch ports. The DCC policy also binds device ports to switch ports. Policies range from
completely restrictive to reasonably flexible, based on customer needs.
