Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a)
OL-16601-01
Caveats
• CSCso65934
Symptom: Virtual interfaces are created by specifying the interface name in configuration mode. If
the interface does not exist, the system creates the interface, and then enters interface configuration
mode. If the user role prohibits access to that interface, this CLI is rejected and the user does not
enter interface configuration mode, although the interface is created. Similarly, if a user does not
have access to a virtual interface, the interface can still be deleted with the no interface command.
Workaround: None.
• CSCso74872
Symptom: When two SNMP walks are started simultaneously, one of them may fail with the
following error:
OID not increasing
This problem does not occur with a single SNMP walk.
Workaround: This is not a permanent failure. Restart the walk and the problem will not occur as
long as there is no other SNMP walk in progress.
• CSCso82992
Symptom: Delete and insert role scopes for a role may fail and display the following error:
entry already exists
The problem occurs when you execute the following steps:
• Delete all role scopes for a role.
• Insert new role scopes for the same role.
Workaround: Repeat the above steps once again.
• CSCso84269
Symptom: Occasionally, when reload is executed after bootup, and there has been no configuration
change, the switch will display the following warning:
'WARNING: There is unsaved configuration!!!'
Workaround: Enter the copy running startup command. The problem will disappear.
• CSCsq10026
Symptom: When the small form-factor pluggable (SFP) is not in the Ethernet port, the show
interface command output displays a bandwidth of 1 Gbps. When the SFP is plugged in, the
bandwidth is displayed correctly (10 Gbps).
Workaround: None.
• CSCsq17571
Symptom: When an SNMP user creates or deletes virtual interface group (VIG), virtual Ethernet
(VEth) or virtual FC (VFC) interfaces, the accounting log displayed by the show accounting log
command does not get updated.
Workaround: Use the CLI for the configuration, which will update the accounting log.
• CSCsq35527
Symptom: When IGMP snooping is enabled on a switch, and the switch is the STP root and an STP
topology change occurs, the IP multicast traffic may take a long time to converge. During this time,
the IP multicast traffic may get affected.
