Setting up FC-FC routing
24
Identifying and deleting stale xlate domains
If a remote edge fabric goes unreachable, the xlate domains created in other edge fabrics for this
remote edge fabric are retained and not removed unless there is any disruption in the local edge
fabric.
You can use the fcrXlateConfig command to identify and remove these stale xlate domains without
disrupting the fabric.
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
FCR authentication
A Brocade Fabric OS router (FCR) is capable of forming a secure link across fabrics. The EX_Port
enabled router will exchange DH-CHAP protocol information with the edge fabric to enable
authentication. Please 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 FCR switch should use the edge switch's WWN to configure the secret keys. Refer to
“Secret key pairs for DH-CHAP” on page 213 for more details.
FCR behaves passively to the authentication requests received from Edge fabric switches. A
Fabric OS Router will never initiate authentication on an EX_Port and will only respond to the edge
fabric requests.
NOTE
Changing the switch auth policy mode does not affect online EX_Port, so it is acceptable to leave the
default Passive policy configured on the Fabric OS 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 580.)
2. Assign backbone fabric IDs. (Refer to “Backbone fabric IDs” on page 581.)
3. Configure FCIP tunnels if you are connecting Fibre Channel SANs over IP-based networks.
(Refer to “FCIP tunnel configuration” on page 582.)
