Configuring Edge Switch parameters

Perform this procedure to configure the following Edge Switch and fabric operating parameters:
Buffer-to-Buffer Credit (BB_Credit), Error Detect Time Out Value (E_D_TOV), Resource Allocation
Time Out Value (R_A_TOV), preferred domain ID and switch priority.
To configure Edge Switch parameters:
1. Set the Edge Switch offline (see
2. Select Configure > Switch > Parameters.

3. Set the Edge Switch parameters:
c. Select (enable) or clear (disable) the Rerouting Delay check box.
If rerouting delay is enabled, traffic is delayed through a fabric by the specified E_D_TOV
time. This delay ensures Fibre Channel frames are delivered to their destination in order, even
if a change to the fabric topology creates a new (shorter) transmission path.
d. Select (enable) or clear (disable) the Domain RSCN check box.
Domain register for state change notifications (domain RSCNs) are sent between end devices
in a fabric to provide additional connection information to HBAs and storage devices. For
example, this information might be that a logical path has been broken because of a
physical event, such as a fiber optic cable being disconnected from a port. Consult with your
HBA and storage device vendor to determine if enabling Domain RSCNs will cause
problems with your HBA or storage products.
