Caveats Send documentation comments to [email protected] • CSCsu66201 Symptom: If the name server IP address is unreachable, the TACACS daemon gets stuck trying to resolve the server names. While it is stuck, TACACS commands, including common commands such as show running-config and copy running-config startup-config, are not processed. Workaround: Fix the network connectivity to the name server IP address. • CSCso65934 Symptom: Virtual interfaces are created by specifying the interface name in configuration mode. If the interface does not exist, the system creates the interface, and then enters interface configuration mode. If the user role prohibits access to that interface, this CLI is rejected and the user does not enter interface configuration mode, although the interface is created. Similarly, if a user does not have access to a virtual interface, the interface can still be deleted with the no interface command. Workaround: None. • CSCso82992 Symptom: Delete and insert role scopes for a role may fail and display the following error: entry already exists The problem occurs when you execute the following steps: • Delete all role scopes for a role. • Insert new role scopes for the same role. Workaround: Repeat the above steps once again. 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 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.
