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.

Symptom: The show startup-config command 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.
CSCsu93313
Symptom: Within a configuration session, 125 unique VACLs are created with a total of 1023
TCAM entries. The verify command fails with the following message:
d2-switch-2(config)# configure session 30
Config Session started, Session ID is 1
d2-switch-2(config-s)# verify
Failed to start Verification: Message Timed Out
d2-switch-2(config-s)# commit
Failed to complete Verification: no free label
This problem occurs with large VACL configurations. Once the Cisco Nexus 5000 Series switch is
in this state, subsequent VACL configurations fail.
Workaround: Reload to recover the configuration.
CSCsv00402
Symptom: When you downgrade from the Cisco NX-OS 4.0(1a)N1 release to a previous software
release, any static IGMP entries that have been configured over an Ether channel are lost after the
downgrade.
Workaround: After you downgrade to the previous release and reload the switch, reconfigure any
static IGMP groups configured over an etherchannel. Alternately, you can also do a copy startup
running to reload the startup configuration. After that do a copy running startup to make sure the
static IGMP entries are re added properly to the startup configuration.
CSCsr64291
Symptom: When a port is congested due to traffic from multiple inputs, the traffic mapped to a
user-defined QoS class can get discarded at a very slow rate (fewer frames per second) in spite of
being configured with strict priority scheduling.
Workaround: None.
CSCsw79515
Symptom: If a Cisco Nexus 2000 Series Fabric Extender is power cycled multiple times in quick
succession, some links between the Cisco Nexus 5000 Series switches and the Cisco Nexus 2000
Series Fabric Extenders may go into an error disabled state.
Workaround: Fabric ports recover after few seconds. No user intervention is required.
