Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1)
OL-16601-01
Caveats
• 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.
• CSCsv00989
Symptom: The command show interface ethernet transceiver details may show all zero values
for DOM-capable 1 G SFP.
Workaround: None.
• CSCsu48008
Symptom: When a Virtual Fibre Channel (VFC) interface is down, the fcIfOperStatusCause MIB
object does not report the correct reason.
Workaround: Get the OperStatus from the CLI using the show interface vfc x command.
• CSCsu77946
Symptom: Within a configuration session, when you enable statistics on the PACL add more than
252 ACES to the ACL, and apply it to an interface, an error message is generated as the statistics
counter is exhausted. Even if you try to remove the statistics keyword, it does not get removed. The
result is that the ACL cannot be applied to the interface. This problem occurs only with a
configuration session, and only after a configuration failure.
Workaround: Reduce the size of the ACL (fewer than 252 ACES) and re-apply the ACL to an
interface. The statistics keyword will still remain and consume hardware resources.
