Setting up FC-FC routing
26
1. Connect to the FC router and log in using an account with admin permissions.
2. Enter the fcrXlateConfig
--show command to identify any stale xlate domains.
3. Enter the fcrXlateConfig
--del command to delete the stale xlate domains.
Example
sw0:root> fcrxlateconfig --show stalexd
Imported FID Stale XD Owner Domain
--------------------------------------------------
012 002 007 ( this FCR )
sw0:root> fcrxlateconfig --del stalexd 12 2
Xlate domain 2 is deleted
FC router authentication
A Brocade FC router (FCR) is capable of forming a secure link across fabrics. The EX_Port-enabled
router exchanges DH-CHAP information with the edge fabric to enable authentication. Note that
while setting secret keys in the edge switch, the front phantom WWN should be used as the remote
switch WWN in the edge fabric. The front phantom domain's WWN is available through the
portCfgExport port command of the EX_Port connecting to the edge fabric. The FC router switch
should use the edge switch's WWN to configure the secret keys. Refer to “Secret key pairs for
DH-CHAP” on page 249 for more details.
FC-FC routing behaves passively to the authentication requests received from edge fabric switches.
An FC router never initiates authentication on an EX_Port and only responds to the edge fabric
requests.
NOTE
Changing the switch authentication policy mode does not affect online EX_Ports, so it is acceptable
to leave the default Passive policy configured on the FC router while the Active or On policy is
required on the edge switch.
Setting up FC-FC routing
To set up FC-FC routing, perform the following tasks in the order listed.
1. Verify that you have the proper setup for FC-FC routing. (Refer to “Verifying the setup for FC-FC
routing” on page 604.)
2. Assign backbone fabric IDs. (Refer to “Backbone fabric IDs” on page 605.)
3. Configure FCIP tunnels if you are connecting Fibre Channel SANs over IP-based networks.
(Refer to “FCIP tunnel configuration” on page 606.)
4. Configure IFLs for edge and backbone fabric connection. (Refer to “Inter-fabric link
configuration” on page 607.)
5. Modify port cost for EX_Ports, if you want to change from the default settings. (Refer to “FC
router port cost configuration” on page 613.)
6. Enable shortest IFL mode if you want to choose a lowest cost IFL path in the backbone fabric.
(Refer to “Shortest IFL cost configuration” on page 615.)
7. Configure trunking on EX_Ports that are connected to the same edge fabric. (Refer to “EX_Port
frame trunking configuration” on page 619.)
