OL-16601-01

CSCsr39670

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.

CSCsu08988

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.

CSCsu32247

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.

CSCsu25775

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

problems occur:
