Caveats Send documentation comments to [email protected] 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.

Resolved Caveats-Cisco NX-OS Release 4.0(1a)N1(1) This section lists the resolved caveats for this release. • CSCso91286 Symptom: When TACACS+ authentication is used to authenticate AAA users using ACS, the Cisco Nexus 5000 Series switch ignores the user to role binding information specified in theACS. Users are logged in with their default roles. The default role for a new user is network-operator and for a user who is an administrator is network-admin. Workaround: The user-to-role binding needs to be configured locally on the Cisco Nexus 5000 Series switch for the role binding to take effect. • CSCsu32247 Symptom: The Cisco Nexus 5000 Series switch executes the power on self test (POST) at bootup to validate hardware integrity of the ASICs. When a Fibre Channel port is connected to an HBA, the HBA driver could assert a LOS that causes a false failure to be reported by POST for one of the ASICs. As a result, all the ports serviced by the ASIC on the GEM are marked for hwFailure. Workaround: Bypass POST at bootup by performing the following steps: switch(config)# diagnostic bootup level bypass switch(config)# copy running-config startup-config switch(config)# reload • CSCsv05115 Symptom: The Cisco Nexus 5000 Series switch crashes if CFS callhome is enabled on a it after a CFS callhome commit is performed on an attached MDS. Workaround: None. OL-16601-01 Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1) 17
