Open Caveats
• CSCsg21537
When MAC addresses are learned on an Etherchannel port, the addresses are incorrectly deleted
from the MAC address table even when the MAC address table aging timeout value is configured to
be longer than the ARP timeout value. This causes intermittent unicast packet flooding in the
network.
The MAC address is automatically relearned after the ARP refresh. The workaround is to enter the
ping ip address privileged EXEC command from the switch to the next hop router to avoid the
intermittent flooding.
• CSCsi08513
MAC flap-notification no longer occurs when a switch is running VLAN bridge spanning-tree
protocol (STP) and fallback bridging is configured on the VLANs running STP.
• CSCsi10584
Multiple Spanning-Tree Protocol (MSTP) convergence time has been improved for Cisco IOS
Release 12.2.
• CSCsi63999
Changing the spanning tree mode from rapid STP to MSTP can cause tracebacks when the virtual
port error-disable feature is enabled when the STP mode is changed.
There is no workaround.
• CSCsi70454
The configuration file used for the configuration replacement feature requires the character string
end\n at the end of the file. The Windows Notepad text editor does not add the end\n string, and the
configuration rollback does not work.
These are the workarounds. (You only need to do one of these.)
– Do not use a configuration file that is stored by or edited with Windows Notepad.
– Manually add the character string end\n to the end of the file.
• CSCsj52956
In Cisco IOS Release 12.2(37)SE or later, the TxBufferFullDropCount counter always increments
even when the switch is a standalone switch.
There is no workaround.
• CSCsj53001
In Cisco IOS Release 12.2(37)SE or later, the Total output drops field in the show interfaces
privileged EXEC command output displays ASIC drops.
– On some interfaces, the Total output drops field is always 0 even though the show platform
port-asic stats drop privileged EXEC command output shows ASIC drops.
– The Total output drops value is the same for all the ports that are linked to the same ASIC.
There is no workaround.
• CSCsj74022
The switch does not correctly update the entPhysicalChildIndex objects from the ENTITY-MIB, and
some of the entPhysicalChildIndex entries are missing from the table. This adversely affects
network management applications such as CiscoWorks CiscoView because they cannot manage the
switch.
There is no workaround.
