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
• CSCtj85867
Symptom: The show running-config command does not show the switchport trunk allowed VLAN
configuration for an interface. This happens when the interface inherits a port-profile and the
allowed VLAN list that contains VLANs configured directly on interface are such that the number
of contiguous VLAN ranges are greater than 64.
Workaround: Use show running-config expand-port-profile to get the effective configuration of the
interface.
• CSCtk08499
Symptom: On doing a snmpwalk of the vtp mib, the system becomes very slow and the VLAN
manager hogs the cpu for several minutes. This happens when vtp is configured and an snmpwalk
of the vtp mib is performed.
Workaround: Avoid doing snmpwalk on the vtp mib when the system is under load or when critical
configuration changes need to be made.
• CSCtj90485
Symptom: When 7m/10m Tyco cables are inserted into 5.0(2)N1(1) based software, the following
warning is displayed:
warning %ETHPORT-3-IF_NON_CISCO_TRANSCEIVER: Non-Cisco transceiver on interface
Ethernet1/10 is detected
Workaround: This is a harmless warning. There is no functionality that is affected.
• CSCth83907
Symptom:
This display issue is exhibited by port-profiles on a Cisco Nexus 5000 Series switch,
running the 5.0(2)N1(1) image. If a port-profile has switchport trunk allowed, VLAN commands
and VLANs are added on the interface, and show running interface does not show the added
VLANs. But show running interface <> expand-port-profile shows the right configuration.
port-profile type ethernet FEX-AA-trunk-port
switchport mode trunk
switchport trunk allowed vlan 101-400
state enabled
sw(config)# interface Ethernet 101/1/1
sw(config-if)# inherit port-profile FEX-AA-trunk-port
sw(config-if)# switchport trunk allowed vlan add 601-603
show running int eth 101/1/1 does not show vlan 601-603
show running int eth 101/1/1 expand-port-profile has 101-400 as well as 601-603
This occurs when an interface that inherits a port-profile has additional VLANs configured on the
interface, in addition to the VLANs in the port-profile.
Workaround: None. This is only a display issue.
• CSCth98138
Symptom:
The VFC name in the output of show fc-port-security for some VFC interfaces is
wrong. This occurs only with large vfc numbers. It does not happen with numbers like VFC311,
VFC3102. and is observed with larger numbers like VFC6000.
Workaround: None.
• CSCti10941
Symptom:
On a Cisco Nexus 5000 Series switch, running a 5.0(2)N1(1) image, the span mode is
incorrectly shown in the show interface brief output.
