Caveats Send documentation comments to [email protected] • CSCsu53299 Symptom: When reloading a switch, a timing condition may cause CFS to enter the handshake before the Routing Information Base (RIB) does. In this instance, CFS will not see any peers, and as a result, CFS-based applications will not communicate with the rest of the fabric. Workaround: Re-initialize CFS by issuing the following commands. This will cause CFS to re-attempt the query to RIB. switch-1# switch-1# switch-1# configure terminal no cfs distribute cfs distribute • CSCsu63218 Symptom: In some cases, there may be duplicate entries of a global pWWN and virtual pWWN as identified in the following scenarios: Switch 1 has a v1and p1 entry and p1 is connected to one of the server interfaces on switch 1. Switch 2 also has a v1and p1 entry along with a v2 and p2 entry; and, switch 2 is in a different CFS region. While using Replace on different switch option in FA wizard, if v1 and p2 is provided in the step4 then, expected operation wont be performed. Workaround: Use the CLI or Device Manager to remove one duplicate entry and then run the wizard again. • CSCsu72195 Symptom: When replaying DMM job configurations saved as an ASCII text file (after performing a write erase), the DMM job includes discrepancies. These discrepancies occur due to the interface and zone configurations that are in an area below the DMM job configuration in the ASCII text file. The configurations stored in the ASCII text file are replayed sequentially from top to bottom. Workaround: None. • CSCsu73264 Symptom: Data Mobility Manager (DMM) uses VSAN 1 for IP communication and it requires interface cpp/1/1 to be configured. If another CPP IP Fibre Channel interface is configured in the same module in a different VSAN, then DMM will not work. Workaround: Delete both CPP IP Fibre Channel interfaces and create only one in VSAN 1. • CSCsu84511 Symptom: When a Cisco MDS switch is configured to use an AAA server using TACACS+ and with enabling the directed request option, a login using @ provides the network-operator privilege instead of the actual privilege mentioned in the ACS server. This happens once aaa accounting is set to remote. A login without enabling the directed request option works as expected and provides the appropriate privilege. This issue does not exist when using the RADIUS protocol with the directed request option enabled. Workaround: Use the RADIUS protocol with the directed request option enabled. • CSCsu87264 Symptom: The Cisco MDS 9000 Family 1/2/4/8-Gbps 24-Port FC Module (DS-X9224-96K9) and the Cisco MDS 9000 Family 1/2/4/8-Gbps 48-Port FC Module (DS-X9248-96K9) go to the OK state when plugged into a Cisco MDS 9216i switch. The MDS 9216i switch does not support these two modules in NX-OS Release 4.1(1b). Workaround: Do not use these unsupported modules in the MDS 9216i switch.
