Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1)
OL-16601-01
Caveats
Workaround: Use RADIUS for directed request authentication.
• CSCsq76688
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.
• CSCsl62545
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.
• 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.
• CSCsr68690
Symptom: When an egress SPAN is configured on a port transmitting jumbo or large frames, the
spanned frames are truncated to 2384 bytes.
Workaround: None.
• CSCsl21529
Symptom: An incorrect MTU value is displayed in the show interface command output. The Nexus
5000 Series switch only supports class-based MTU. Per-interface level MTU configuration is not
supported. The switch supports jumbo frames by default. However, the show interface command
output currently displays an incorrect MTU value of 1500 bytes.
Workaround: None.
• CSCsm03765
Symptom: The Set operation on the CISCO-IP-IF-MIB is not supported. You cannot set the mgmt0
IP address using SNMP.
