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.

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.

•
Symptom: When you restore a configuration to running-config from a configuration file, ACL
manager may leak memory. The size of the leak is related to the size of ACL configurations and the
number of times the restoration occurs. The switch may reboot if the ACL configuration is very large
and the restoration occurs too many times.
Workaround: None.

•
Symptom: TACACS+ fails if the user name input at login initiates a directed request authentication.
The syntax to authenticate a directed request to a switch is username@(IP address or name of
TACACS+ server).
Workaround: Use RADIUS for directed request authentication.

Symptom: The neighboring device for the Cisco Discovery Protocol (CDP) is not removed after
shutting down the port for CDP hold time interval.
Workaround: None.

Symptom: The fan LED on the Device Manager (DM) displays in amber color even though the fan
is working properly.
Workaround: None.
CSCsr28868
•
Symptom: When the Fibre Channel over Ethernet (FCoE) feature is disabled, any untagged Ethernet
packet with 00 00 in the Ethertype/length field is treated as an invalid packet and is forwarded out
with a bad Ethernet CRC.
Workaround: None.
•
CSCsr35452
Symptom: When the ntp peer command is configured on the MDS fabric and is distributed using
CFS, the Nexus 5000 Series switch appends an incorrect VRF name AC to the command instead of
VRF management.
Workaround: Use the ntp server command to synchronize time across the fabric.
•
CSCsr36661
Symptom: When IGMP group membership is statically configured with private VLAN (PVLAN)
host ports, the hardware gets programmed correctly. However, the membership information is not
programmed for PVLAN host ports after the switch is reloaded.
Workaround: Delete and add the private VLAN association once again.
