Fabric configurations for interconnectivity
A
To allow interconnectivity with M-EOS SANs, use the -m option on the portCfgEXPort command to
indicate the connectivity mode. Table 98 lists the valid parameters to use with the -m option to set
the connectivity mode.
You can display the current operational mode of the EX_Port by issuing the portCfgExPort
command with the port number as the only parameter.
The following command sequence is an example to connect port 5 to an M-EOS fabric in McDATA
Fabric Mode:
switch:admin> portdisable 5
switch:admin> portcfgexport 5 -m 2
switch:admin> portenable 5
See “Inter-fabric link configuration” on page 468 for details about the portCfgExPort command,
which is used for McDATA Fabric mode on Fabric OS v5.2.0 or later.

Configuring the FC router

When configuring a Fabric OS fabric to connect to a Native McDATA fabric, you must perform some
preparation on the FC router. The following procedure shows how to connect an EX_Port of an FC
router to a Native McDATA fabric configured in Fabric mode.
NOTE
For additional information on configuring the FC router, refer to Chapter 21, “Using the FC-FC Routing
Service”.
1. To verify the Native McDATA firmware version, use the M-EOSc show system command.
2. To display the front domain on the M-EOS fabric, use the M-EOS showfabric topology
command.
3. Using the Fabric OS firmwareShow command, make sure that Fabric OS v6.4.0 or later is
installed on the FC router, as shown in the following example:
B7800_170:admin> firmwareshow
Appl Primary/Secondary Versions
------------------------------------------
FOS v6.4.0
v6.4.0
4. On the FC router, use the portDisable command to disable the EX_Port that you will use to
connect to the M-EOS switch. Ports are persistently disabled by default.
5. Enter the portCfgExPort command to configure the port as an EX_Port with a different FID
within the McDATA Fabric Mode.
This port can now connect to an M-EOS switch in McDATA Fabric mode or McDATA Open mode.
