Symptom: Although SNMP notification is enabled on the switch, traps for the power supply and fan
modules are not received.
Workaround: None.
CSCsr47531
Symptom: When a VSAN is configured as SPAN source, traffic from all the member ports is
spanned to the SPAN destination port. When a switch is rebooted, the VSAN SPAN source remains
in the down state.
Workaround: Delete and add the VSAN sources for the SPAN session.

Symptom: Telnet access is available only after reloading the Nexus 5020 switch with the no telnet
server enable command running.
Workaround: Execute the no telnet server enable command once again after reload even if the
command is saved in the startup-config. Additionally, you can also apply filters to the SVI to allow
only trusted hosts to communicate with the system.

Symptom: The Nexus 5000 Series switch executes the power-on self-test (POST) at bootup to
validate hardware integrity of the ASICs. When a Fibre Channel port is connected to a host bus
adapter (HBA), the HBA driver can trigger a signal loss that causes a false failure to be reported by
POST for one of the ASICs. As a result, all the ports serviced by the ASIC on the GEM are marked
for hardware failure.
Workaround: Do not connect HBAs to the FC expansion modules.
CSCsu40126
Symptom: When the Nexus 5000 Series switch is configured to operate in the N-port virtualization
(NPV) mode, the LOGOs received over the server port are not processed properly. This results in
stale Fibre Channel IDs at the switch.
Workaround: Perform shut and no shut command operations on all the server ports to clear the
stale state on the NPV switch.
CSCsm66194 and CSCsr66209
Symptom: Logins may not be uniformly balanced across all available border ports when the Nexus
5000 series switch operates in the NPV mode under conditions such as the following:
• The switch is reloaded.
• NPIV is disabled and re-enabled on the NPV core-switch.
• The NPV core-switch is reloaded.
• A new NP link is added.
Workaround: Perform shut and no shut command operations on all the server ports to rebalance
the logins.

Symptom: When the Nexus 5020 Series switch is connected to a 110 V power supply, the following
problems occur:
