Cisco Nexus 5000 Series and Cisco Nexus 2000 Series Release Notes, for Cisco NX-OS Release 5.0(2)N1(1) and NX-OS Release 5.0(2)N2(1)

Caveats
Symptom: Sometimes, SPAN stops working on the Cisco Nexus 5000 Series.
Workaround: Flapping the SPAN destination again recovers the SPAN traffic

Symptom:
When an interface is pre-provisioned with non-default config, issuing a show running
command with the all keyword at the end, default config is still displayed along with the newly
configured non-default config. This can be confusing, as it would seem as if conflicting config is
present. This is only a display issue, no functional impact. The default config is not actually applied.
For example, if "switchport mode trunk" is configured on int eth 1/1, the following is seen for show
run interface ethernet1/1: interface Ethernet1/1 switchport mode access switchport mode trunk This
problem does not exist for a regular show running-config request, only when "all" is specified at the
end. This happens when you configure any non-default config on a pre-provisioned interface, and
issue a show run command with the all keyword.
Workaround: None. There is no behavioral impact. Seethe show running command without all.

Symptom:
On a Cisco Nexus 5000 Series switch, running a 5.0(2)N1(1) image, when a peer-link
comes up and vPC ports are in the process of coming up, if the peer switch reboots, there is a small
window where the vPC ports do not come up due to the peer-link being down.
Workaround: Perform a shut/no shut operation on the vPC ports.
• CSCti86620

When you configure the interface beacon and copy the config to startup-config 2 and
reload the switch teh following message is displayed:
check interface LED ### Reproducibility reproducible ### Impact LED is not flashing
after switch reload ### Expected Behavior LED should be flashing
Workaround: None.

The pause no-drop config for class-fcoe differs between checkpointed configuration and
running-configuration of the Cisco Nexus 5000 Series switch.
