Symptom: Configure duplicate IP address for multiple SVI interfaces.
Workaround: Do not configure two or more SVIs with the same IP address.
CSCsx80279
Symptom: When traffic is sent at line rate as a single burst, all addresses are not learned when egress
interfaces are FEX facing ports. This problem does not occur if sustained traffic is sent for more than
0.4 seconds.
Workaround: Resending the unlearned MAC addresses would render them relearned.

Symptom: When a Cisco Nexus 2000 Fabric Extender is already online and a fabric interface that is
not part of a port channel is configured with a serial number that does not match that of the FEX,
the fabric interface will be brought down, and show interface fex does not display the reason for
being down.
Workaround: None. This is a display issue.
CSCsy02439
Symptom: Under some circumstances, the FC MAC driver displays the following error message:
%KERN-3-SYSTEM_MSG: FCP_ERRFCP_PORT: gat_fcp_isr_ip_fcmac_sync_intr@424, jiffies =
0x1c422:Unknown intr src_id 41 - kernel
The error message is when an unused interrupt in the MAC fires. The error message does not
indicate any functional problem.
Workaround: None
CSCta78541
Symptom:
VSH crashes and generate a core when you do the following:
attach fex 102
show system error-id list
The Cisco Nexus 2000 Fabric Extender does not reload and the core does not impact the
functionality of the Fabric Extender.
Workaround: None

Symptom: DCBX fails to converge between a Nexus 5000 switch running 4.1(3)N1(1) and another
Nexus 5000 switch running a 4.0(1a)N based release. As a result, priority-flow-control does not
work on this link.
Workaround: None.
CSCta85268
Symptom: When you downgrade from release 4.1(3)N1(1) to 4.0(1a)N-based releases using Fabric
Manager or when you upgrade from a 4.0(1a)N-based release to 4.1(3)N1(1) using Fabric Manager
