McDATA Sphereon 4400 Fabric Switch Installation and Service Manual
Installation Tasks
• Switch binding - Use the Switch Binding option from the
Configure menu (Configure>Switch binding) to create a
membership list of node (device) WWNs that can attach to the
product. The specified connection policy restricts product access
through E_Ports, F_Ports, or in general (all ports).
To configure optional features, refer to the EFC Manager Software
Release 8.7 User Manual (620-000170) for instructions.

Interswitch Links
This section describes ISL performance features configured through
the SAN management or Element Manager applications. The
OpenTrunking feature requires PFE key installation. Refer to
Installing PFE Keys (Optional) for instructions. Features include:
• OpenTrunking - Use the OpenTrunking option from the Configure
menu (Configure>Open Trunking) to optimize ISL bandwidth. The
feature monitors data rates (congestion and BB_Credit starvation)
through multiple ISLs and load balances traffic (from congested
to uncongested links) accordingly.
• Preferred path - Use the Preferred Path option from the Configure
menu (Configure>Preferred Path) to specify and configure one or
more ISL data paths between multiple fabric elements. At each
fabric element, a preferred path consists of a source port, exit
port, and destination Domain_ID.
• Port fencing - Use the Port Fencing option from the Configure
menu (Configure>Port fencing) to minimize ISLs that bounce
(repeatedly attempt to establish a connection), causing disruptive
fabric rebuilds. Fencing defines a bounce threshold that when
reached, automatically blocks the disruptive E_Port.
To configure features, refer to the EFC Manager Software Release 8.7
User Manual (620-000170) for instructions. If no additional options or
features are to be configured, continue to the next task.
