Caveats Send documentation comments to [email protected] Workaround: Configure a shorter query interval on the IGMP router to reduce the time it takes for ip-multicast traffic to converge in this topology. • CSCsq35728 Symptom: When a SAN port channel is created, the following syslog message is displayed: 2008 May 20 06:09:13 switch %PORT_CHANNEL-3-MSG_SEND_FAILURE: failed to send MAP_PARAM_FROM_CHANNEL to sap 45: Broken pipe" There is no functionality loss and this message can be ignored. Workaround: None. • CSCso01268 Symptom: The following error message is displayed when a module is hot-swapped out: 2005 Jan 1 00:08:23 switch %KERN-4-SYSTEM_MSG: SI-VDC map entry does not exist! - kernel" There is no functionality loss and the message can be ignored. Workaround: None. • CSCsq57558 Symptom: Enhanced Inter Switch Link (EISL) encapsulation is not supported on a Fibre Channel SPAN destination port. When EISL encapsulation is configured on the SPAN destination (SD) port, a VFT header is added to the packets going out of the SD port. The VFT header has VSAN information that helps distinguish traffic for various VSANs. This applies to any Fibre Channel SPAN source. By default, EISL encap is not added and packets are sent out without a VFT header, and independent of the type of SPAN source port. For a Nexus 5000 Series switch, the switchport encap EISL command does not have any effect. Workaround: Use the Ethernet SPAN destination port to SPAN Fibre Channel traffic. FCoE packets going out of the Ethernet SPAN destination port will contain VSAN information in the Ethernet VLAN tag. • CSCsq90423 Symptom: EISL encapsulation is not supported on Fibre Channel SPAN destination port in NPV mode. When EISL encapsulation is configured on the SPAN destination (SD) port, a VFT header is added to the packets going out of the SD port. The VFT header has VSAN information, which helps distinguish traffic for various VSANs. This applies to any Fibre Channel SPAN source. By default, EISL encapsulation is not added and packets are sent out without a VFT header, and independent of the type of SPAN source port. For a Nexus 5000 Series switch, the switchport encap EISL command does not have any effect. Workaround: Use the Ethernet SPAN destination port to SPAN Fibre Channel traffic. FCoE packet going out of the Ethernet SPAN destination port will contain VSAN information in the Ethernet VLAN tag. Resolved Caveats-Cisco NX-OS Release 4.0(1a)N1(1a) This section lists the resolved caveats for this release. • CSCsy65407 Symptom: In the Cisco NX-OS 4.0(1a)N1(1) release, if an RBAC role has more than 67 rules configured, show running-config causes the vshd process to core dump. This caveat exists in the 4.0(0)N1(2a) and 4.0(1a)N1(1) releases. Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a) 18 OL-16601-01
