Caveats Send documentation comments to [email protected] • CSCsv70815 Symptom: The default VRF is the system default for a VRF setting. Ideally, applications using VRF (such as TACACS+) assume a default VRF value if a VRF configuration is not specified by the administrator. However, TACACS+ is not set up properly unless the default VRF is configured. Workaround: The Cisco Nexus 5000 Series switches support two possible VRFs, the default and the management. Configure the desired VRF when using TACACS+ service. You can configure the desired VRF using either of these configurations: aaa group server tacacs+ t1 server 10.193.149.54 use-vrf management aaa group server tacacs+ t2 server 20.1.1.2 use-vrf default • CSCsu01188 Symptom: No traps are sent when SFPs for GE and 10GE are removed or inserted. Workaround: None. • CSCsv56881 Symptom: Each Switched Virtual Interface (SVI) for inband management must be configured with a different IP address. IPv6 has an error check feature. When an administrator enters a duplicate IPv6 address across two SVIs, the software fails the command due to the duplicate address. A similar error check should exist for IPv4 address configuration on SVIs. Workaround: Do not configure duplicated IPv4 or IPv6 addresses. • CSCsv52513 Symptom: The VLAN interface 1 is internally created by the SVI daemon by default, so this VLAN interface cannot be deleted from the CLI. Workaround: None. • CSCsv24214 Symptom: When downgrading a Cisco Nexus 5000 Series switch from running a 4.0(1a)N1 image to a 4.0(0)N1(1) or 4.0(0)N1(1a) image, the startup configuration is not restored. This is caused by the defect CSCsq74395, which was resolved in 4.0(0)N1(2) and 4.0(0)N1(2a). Workaround: After a downgrade, manually copy the startup configuration to the running configuration and reboot the system. • CSCsv02866 Symptom: The command show interface ethernet transceiver details may show invalid calibration for DOM-supported 1 G SFP. Workaround: None. • CSCsv10783 Symptom: The show startup-config does not show the correct mode for a channel group. It shows the current mode for the channel group. The correct mode is stored. On a subsequent reload, the correct mode is configured on the channel group. The show startup-config always shows the current mode instead of the mode that was saved to startup. On a subsequent reload, the correct mode is configured. This is only a show command issue. Workaround: None. OL-16601-01 Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a) 13
