Viewing Product and Fabric Data
• Rerouting Delay — Indicates whether rerouting delay is enabled. Enabling the
rerouting delay ensures that frames are delivered in order through the fabric to
their destination.
• Domain RSCNs — Domain register for state change notifications (domain
RSCNs) are sent between end devices in a fabric to provide additional connection
information to host bus adapters (HBA) and storage devices. This option is
required if Enterprise Fabric mode (an optional SANtegrity feature) is enabled.
• Operating Mode — Indicates whether the operation mode is S/390 mode or
Open Systems mode. (S/390 mode is not supported with the Edge Switch 2/24.)
• Director Speed — speed of communications on the product. Values can be
1Gbps or 2 Gbps. Valid on the Director 2/64 only.
