HP Brocade 4Gb SAN Switch for HP BladeSystem p-Class - Manual (Page 226)

226 Using Remote Switch
You must connect the fabrics through the gateway device, and make sure that the
configure
command
parameters are compatible with the gateway device.
You may be required to reconfigure the following parameters, depending on the gateway requirements:
• R_A_TOV: Specify a Resource Allocation Timeout Value compatible with your gateway device.
• E_D_TOV: Specify a Error Detect Timeout Value compatible with your gateway device
• Data field size: Specify the maximum Fibre Channel data field reported by the fabric. Verify the
maximum data field size the network-bridge can handle. Some bridges may not be able to handle a
maximum data field size of 2112.
• BB credit: Specify the number of Buffer-to-Buffer credits for Nx_port devices.
• Suppress Class F Traffic: Use this parameter to disable class F traffic. Some network-bridge devices
may not have a provision for handling class F frames. In this case, the transmission of class F frames
must be suppressed throughout the entire Remote Switch fabric.
To set the access and reconfigure these parameters:
1. Connect to the switch and log in as admin.
2. Issue the
switchdisable
command to disable the switch.
3. Issue the
configure
command.
4. Enter
yes
at the
Fabric Parameters
prompt.
5. Press Enter to scroll through the Fabric Parameters without changing their values, until you reach the
parameter you want to modify.
6. Specify a new parameter value that is compatible with your gateway device.
7. Press Enter to scroll through the remainder of the configuration parameters. Make sure that the
configuration changes are committed to the switch.
8. Repeat for all switches in the fabrics to be connected through a gateway device. These parameters
must be identical on each switch in the fabric, and between fabrics connected through the
gateway device.
