Caveats Send documentation comments to [email protected] • CSCsx60187 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. • CSCsy99816 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 • CSCta74119 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 error messages such as the following are generated: 2009 Jul 19 15:32:55 N5K-C snmpd: SNMP Operation (GET) timed out. reqId (1448314586) errno (62) on iso.3.6.1.4.1.9.9.360.1.1.4.2.0 2009 Jul 19 15:32:56 N5K-C snmpd: SNMP Operation (GET) failed.
