Upgrade and downgrade considerations for FC-FC routing
24
FIGURE 84 Backbone-to-edge routing across base switch using FC router in legacy mode
Upgrade and downgrade considerations for FC-FC routing
When you upgrade to Fabric OS v7.0.0 or later, EX_Ports remain functional and you can continue to
perform all FC router operations on the switch.
Brocade recommends that you save your FC-FC routing configuration (using the configUpload
command) before performing any downgrades.
For further instructions on downgrading, refer to Chapter 9, “Installing and Maintaining Firmware”.
How replacing port blades affects EX_Port configuration
If you replace an FR4-18i blade with an 8-Gbps port blade or FX8-24 blade, the EX_Port
configuration remains the same for the first 16 ports on the 8-Gbps port blade (and for the first 12
FC ports on the FX8-24 blade). For all other ports on the blade, the EX_Port configuration is
cleared. No ports are persistently disabled.
If you replace an 8-Gbps port blade with an FX8-24 blade, the EX_Port configuration remains the
same for the first 12 FC ports on the FX8-24 blade.
If you replace an 8-Gbps port blade or FX8-24 blade with another 8-Gbps port blade, the EX_Port
configuration remains the same.
Displaying the range of output ports connected to xlate domains
The edge fabric detects only one front domain from an FC router connected through multiple output
ports. The output port of the front domain is not fixed to 0; the values can be in a range from 129
through 255. The range of the output ports connected to the xlate domain is from 1 through 128.
This range enables the front domain to connect to 127 remote xlate domains.
