Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• Some traffic that ingresses through one DFC-equipped module and egresses through another 
DFC-equipped module might be dropped. This problem is resolved in Release 12.1(13)E10. 
(CSCeb83650)
• With CBAC and RPR+ redundancy configured, all TCP and UPD sessions fail after a switchover to 
the redundant supervisor engine. This problem is resolved in Release 12.1(13)E10. (CSCeb87003)
• Following a reload, a Supervisor Engine 2 with the no mls qos channel-consistency command 
configured might display an erroneous “qos-card type” mismatch message for an EtherChannel and 
incorrectly refuse to include some of the ports in the EtherChannel. This problem is resolved in 
Release 12.1(13)E10. (CSCec00966)
• With a Supervisor Engine 2, if you enter a clear mac-address-table dynamic command, traffic 
between DFC-equipped and nonDFC-equipped modules might be dropped for approximately 10 
minutes. This problem is resolved in Release 12.1(13)E10.
• After an RPR+ switchover, if you have configured the mls ip directed broadcast command, all 
broadcast traffic is sent to the MSFC to be processed in software. This problem is resolved in 
Release 12.1(13)E10. (CSCec07319)
• A redundant supervisor engine might incorrectly run out of memory while in the standby state and 
be unable to support a switchover. This problem is resolved in Release 12.1(13)E10. (CSCec08966)
• With port security enabled, a memory leak might occur. This problem is resolved in 
Release 12.1(13)E10. (CSCec14266)
Resolved General Caveats in Release 12.1(13)E9
• When you configure interface speed and duplex mode, you must configure speed before you can 
configure the duplex mode. The speed and duplex mode configuration is stored in the configuration 
file in reverse order, which causes duplex mode configuration failure if you paste in a configuration 
file. This problem is resolved in Release 12.1(13)E9. (CSCea93829)
• The definitions of some MIB objects are incorrectly of type Counter32 instead of type Gauge32. 
This problem is resolved in Release 12.1(13)E9. (CSCdz65045)
• Environmental polling is invalid on a redundant supervisor engine. This problem is resolved in 
Release 12.1(13)E9. (CSCdy64272)
• If you enter a show interface etherchannel command or a show interface etherchannel module 
command for an EtherChannel with ports on a module that is no longer installed, the MSFC might 
reload or there might be a switchover to a redundant supervisor engine. This problem is resolved in 
Release 12.1(13)E9. (CSCeb53215)
• With a redundant supervisor engine installed, the configuration of EtherChannels that are 
reconfigured from Layer 2 to Layer 3 is not synchronized to the redundant supervisor engine. This 
problem is resolved in Release 12.1(13)E9. (CSCeb56353)
• With a redundant supervisor engine installed, if you enter the switchport or no switchport 
command in interface range mode, the configuration on the redundant supervisor engine for the 
range of interfaces might not be synchronized. This problem is resolved in Release 12.1(13)E9. 
(CSCea23123)
Resolved General Caveats in Release 12.1(13)E8
• A memory leak might occur with Layer 2 aging and EtherChannels that include ports on different 
DFC-equipped modules configured. This problem is resolved in Release 12.1(13)E8.
