Fabric binding -
Use the Fabric Binding View to lock parameters of
a fabric in accordance with the user configuration. Fabric binding
creates a membership list of element (director or switch)
Domain_IDs and worldwide names (WWNs) that can
communicate with the product.
• Switch binding - Use the Switch Binding View 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).
• Port binding - Use the Port Binding View to bind an attached
device WWN to a product Fibre Channel port.
To configure optional features, refer to the EFCM Basic Edition User
Manual (620-000240) for instructions.
Configure interswitch links
This section describes optional ISL performance features configured
through
Configure menu selections. Features include:
• Open Trunking - Use the Open Trunking View 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 View 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 View 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 optional features, refer to the EFCM Basic Edition User
Manual (620-000240) for instructions. If no additional options or
features are to be configured, go to Task 20: Cable Fibre Channel ports .
