Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a)
OL-16601-01
Caveats
• 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.
