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)
OL-22747-02
Caveats
Symptom: When priority tagged frames are received on Cisco Nexus 2000 Series Fabric Extender
ports, they are dropped and not forward on the native or default VLAN of the port. The MAC
addresses are not learned.
Workaround: None.
• CSCtl87240
Symptom: Switch profile commands are removed from the running configuration when the switch
profile is deleted. This occurs when you issue the no switch-profile name all-config | local-config
command.
Workaround: Make a backup copy of the running configuration before deleting the switch profile
and restore your startup configuration after the switch profile has been deleted. To restore the startup
configuration, use the copy startup-config running-config command.
• CSCtl87260
Symptom: Removing a switch profile from a configuration disrupts some configurations that were
present in the running configuration, for example port channel and vPC configurations. This occurs
when you issue the no switch-profile name all-config | local-config command.
Workaround: Make a backup copy of the running configuration before deleting the switch profile
and restore your startup configuration after the switch profile has been deleted. To restore the startup
configuration, use the copy startup-config running-config command.
Resolved Caveats—Cisco NX-OS Release 5.0(2)N2(1)
This section lists the resolved caveats for this release.
The caveats in this section are resolved in Cisco NX-OS Release 5.0(2)N2(1) but may be open in
previous Cisco NX-OS releases.
• CSCtk03738
Symptom: On Cisco Nexus 2000 Fabric Extenders, multicast packets are forwarded on multiple
FEX ports.
Workaround: Enable IGMP snooping, then use static IGMP entries to add multicast receivers to
the switch MAC table if the host is unable to send an IGMP group membership report. Alternatively,
upgrade the host application to support the IGMP protocol so it can automatically send IGMP
join/leave reports without a static configuration on the switch.
• CSCtk33187
Symptom: A Cisco Nexus 5500 Platform switch may fail when an expansion module is removed
from the switch and the expansion module has fabric ports that are used for control traffic.
Workaround: Before removing the expansion module from the switch, use the show fex detail
command to display the fabric ports that are used for control traffic then use the shut command to
shut down the fabric ports. Because the expansion module is removed, using the shut command on
the fabric ports should not have any functional impact.
• CSCth47056
Symptom: On a Cisco Nexus 5000 Series switch running NX-OS Release 5.0(2)N1(1),
switch-profiles that are created by one user cannot be modified by an another user. The following
error is displayed when a different user tries to modify the switch-profile.
N5k(config-sync)# switch-profile SYNC
Error: Session is owned by another user
