Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a)
OL-16601-01
Caveats
• CSCsv00989
Symptom: The command show interface ethernet transceiver details may show all zero values
for DOM-capable 1 G SFP.
Workaround: None.
• CSCsu48008
Symptom: When a Virtual Fibre Channel (VFC) interface is down, the fcIfOperStatusCause MIB
object does not report the correct reason.
Workaround: Get the OperStatus from the CLI using the show interface vfc x command.
• CSCsu77946
Symptom: Within a configuration session, when you enable statistics on the PACL add more than
252 ACES to the ACL, and apply it to an interface, an error message is generated as the statistics
counter is exhausted. Even if you try to remove the statistics keyword, it does not get removed. The
result is that the ACL cannot be applied to the interface. This problem occurs only with a
configuration session, and only after a configuration failure.
Workaround: Reduce the size of the ACL (fewer than 252 ACES) and re-apply the ACL to an
interface. The statistics keyword will still remain and consume hardware resources.
• CSCsu93313
Symptom: Within a configuration session, 125 unique VACLs are created with a total of 1023
TCAM entries. The verify command fails with the following message:
d2-switch-2(config)# configure session 30
Config Session started, Session ID is 1
d2-switch-2(config-s)# verify
Failed to start Verification: Message Timed Out
d2-switch-2(config-s)# commit
Failed to complete Verification: no free label
This problem occurs with large VACL configurations. Once the Cisco Nexus 5000 Series switch gets
into this state, subsequent VACL configurations fail.
Workaround: A reload is needed to recover the configuration.
• CSCsu50589
Symptom: If an invalid IP address is configured within a RADIUS configuration (such RADIUS
server), any manipulation of the RADIUS configuration causes timeouts to the console such as show
running-configuration or copy running to startup.
Workaround: Configure a valid IP address for a RADIUS configuration.
• CSCsv19979
Symptom: Any FC port set to SD mode does not come up until the speed is configured manually.
The port goes into the Error disabled state and the only way to bring it online as SD is to manually
set the speed 2 G or 4 G.
Workaround: Configure the speed manually to 2 G or 4 G.
• CSCsv00402
Symptom: When you downgrade from the 4.0(1a)N1 release to a previous software release, any
static IGMP entries that have been configured over an Ether channel are lost after the downgrade.
