McDATA Mi10K interoperability
A
McDATA Mi10K interoperability
When an EX_Port is connected to an M-EOS edge fabric, the front domain ID must be within a range
the edge M-Series switch can understand. Valid values are:
• McDATA Native mode: 1 – 31
• McDATA Open mode: 239
The default front domain ID assigned to the EX_Port remains at 160 when it is created. However,
when the EX_Port is connected to the Mi10K, a daemon sends a request domain ID (RDI)
command that must be within the valid range M-EOS understands.
When an RDI command is sent to an Mi10k switch with a valid domain ID defined by standards and
is not within the range an Mi10k switch understands, the RDI request is rejected. This behavior of
the Mi10k is different from other M-EOS switches.
If you set a front domain ID that is not within the valid range M-EOS understands, then in Fibre
Channel routing, a daemon internally requests a valid domain ID that M-EOS understands. Unless
you change the front domain ID, there is no impact.
The behavior with non-Mi10k switches displays the regular switch when configured.
After the port is properly configured and connected, running switchShow on the FC router displays
the M-EOS switch that is connected. From the M-EOS side, the show fabric topology command
displays the front domain. If the LSAN is configured and proxy devices are created, the proxy device
appears in the name server of the edge fabric, and the xlate domain appears in the edge fabric.
Fabric configurations for interconnectivity
When connecting a Fabric OS fabric with an M-EOS fabric using an FC Router, you must configure
the switch on both fabrics as well as the router, as described in the following sections.
NOTE
Trunking is not supported on EX_Ports connected to the M-EOS fabric.
Connectivity modes
You can connect to M-EOS fabrics in both McDATA Open mode or McDATA Fabric mode. If the mode
is not configured correctly, the port is disabled because of incompatibility.
To allow interconnectivity with M-EOS SANs, use the -m option on the portCfgEXPort command to
indicate the connectivity mode. Table 96 lists the valid parameters to use with the -m option to set
the connectivity mode.
TABLE 96 portCfgEXPort -m values
Value Description Use
0 Brocade Native Default mode.
1 McDATA Open Mode 1 When the neighboring M-EOS switch is running in open mode.
2 McDATA Fabric Mode (native mode) When the neighboring M-EOS switch is running in native mode.
3 McData Fabric legacy mode Not currently used.
