Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• In a release where caveat CSCeb06811 is resolved and with STP loop guard configured, two ports
connected together might incorrectly stay in the STP loopguard loop-inconsistent state. This
problem is resolved in Release 12.1(23)E. (CSCee45170)
• While traffic is flowing, CPU utilization might increase to a very high level if you reconfigure an
EtherChannel from Layer 3 to Layer 2 and configure a Layer 3 VLAN interface for the
EtherChannel. This problem is resolved in Release 12.1(23)E. (CSCee41100)
• Traffic might be lost when communication fails between the supervisor engine and the MSFC. This
problem is resolved in Release 12.1(23)E: an intentional reload occurs when communication fails
between the supervisor engine and the MSFC. (CSCee39004)
• With very large flows, the NetFlow Data Export (NDE) byte counts might be incorrect (NDE packet
counts remain correct). This problem is resolved in Release 12.1(23)E. (CSCee23058)
• If you enter the mls ip multicast non-rpf netflow and mls ip multicast consistency-check
commands, the show mls ip multicast consistency-check command displays “mdb missed for a
shortcut” for non-RPF traffic, because non-RPF traffic has no (S,G) entry in the multicast routing
table. This problem is resolved in Release 12.1(23)E. (CSCee22471)
• Following a Route Processor Redundancy Plus (RPR+) mode switchover, if you enter the reload
command, you are prompted to save the configuration when the configuration has not been changed.
This problem is resolved in Release 12.1(23)E. (CSCee05637)
• When you configure Network Based Application Recognition (NBAR) on a LAN port, there is no
message that the NBAR traffic is processed in software on the MSFC. This problem is resolved in
Release 12.1(23)E. (CSCed90255)
• SNMP access of the CISCO-SWITCH-ENGINE-MIB might cause tracebacks. This problem is
resolved in Release 12.1(23)E. (CSCed85167)
• The VLAN translation feature does not work on WS-X6816-GBIC modules. This problem is
resolved in Release 12.1(23)E. (CSCed73700)
• You cannot disable the power reserved for empty slots. This problem is resolved in
Release 12.1(23)E: you can enter the no power enable module command for an empty slot.
(CSCed56651)
• A VLAN interface configured on a VLAN that is carrying Layer 2 protocol tunneling traffic
processes untagged CDP frames and displays the CDP-frame-source devices as CDP neighbors.
This problem is resolved in Release 12.1(23)E. (CSCed55283)
• Cisco IOS software does not prevent simultaneous erase nvram: and write memory commands
from different Telnet or console sessions. This problem is resolved in Release 12.1(23)E.
(CSCea20169)
• No CDP packets are received if you enter the dlsw ethernet redundancy-enable command on a
VLAN interface. This problem is resolved in Release 12.1(23)E. (CSCee39240)
• You might see these messages with a large ARP table and heavy ARP traffic:
%SYS-3-CPUHOG: Task ran for 2376 msec (6/4), process = ARP Input, PC =40292C18.
-Traceback= 40292C20 401D8624 401D8610
%SYS-3-CPUHOG: Task ran for 2160 msec (18/13), process = ARP Input, PC = 40292C18.
-Traceback= 40292C20 401D8624 401D8610
This problem is resolved in Release 12.1(23)E. (CSCed28402)
• The BGP set community none command does not work; prefixes are not advertised to external
peers. This problem is resolved in Release 12.1(23)E. (CSCeb69972)
• Spurious memory accesses might occur if you remove DECnet configuration commands associated
with a tunnel interface. This problem is resolved in Release 12.1(23)E. (CSCee88936)
