Caveats
Workaround: If system configuration is to be restored from a configuration file (copied locally or
through tftp), you can separate the FEX interface part of the configuration (if any) into a different
file. Copy the main file first, then wait for FEX to come online, and then copy the separate FEX
interface configuration file. Alternately, you can copy twice.
• CSCsv81694
Symptom: The auto learn static MAC entry is removed if the port on which the same MAC address
is dynamically learned is flapped. The static MAC address is removed from the software as well as
the hardware.
Workaround: Re-add the static MAC entry through the CLI.
• CSCsv56881
Symptom: Each Switched Virtual Interface (SVI) for inband management must be configured with
a different IP address. IPv6 has an error check feature. When an administrator enters a duplicate
IPv6 address across two SVIs, the software fails the command due to the duplicate address. A
similar error check should exist for IPv4 address configuration on SVIs. ( See also CSCsx60187)
Workaround: Do not configure duplicated IPv4 or IPv6 addresses.
• CSCsv02866
Symptom: The command show interface ethernet transceiver details may show invalid
calibration for DOM-supported 1 G SFP.
Workaround: None.
• CSCsv00989
Symptom: The show interface ethernet transceiver details command may show all zero values
for a DOM-capable 1 G SFP.
Workaround: None.
• 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 remains and consumes hardware resources.
• 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.
• CSCsr20499
Symptom: When you restore a configuration to running-config from a configuration file, ACL
manager may leak memory. The size of the leak is related to the size of ACL configurations and the
number of times the restoration occurs. The switch may reboot if the ACL configuration is very large
and the restoration occurs too many times.
Workaround: None.
