Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
Resolved Caveats in Release 12.1(5a)E
• Support for mobile IP was inadvertently deleted. This problem is resolved in Release 12.1(5a)E1.
(CSCds78103)
• Clock synchronization between the MSFC and the supervisor engine on the Catalyst 6500 series
switches is broken and affects other subsystems. This problem is resolved in Release 12.1(5a)E.
(CSCds72622)
• The input and output fields of NDE version 7 records are not updated with the snmp_if_index of the
ingress and egress interfaces. This problem is resolved in Release 12.1(5a)E. (CSCds39850)
Note Regarding the resolution of CSCds39850, the index stored for the input interface is that of
the candidate packet that created the shortcut. Other flows with a similar flow specification
that enter the switch on other interfaces can take the same shortcut, but the probability of
this can be reduced if you use a more granular flow mask (source-destination or full-flow).

Open FlexWAN Module Caveats in Release 12.1(5c)E12
• When converting from Catalyst software to Cisco IOS on both the supervisor engine and MSFC, the
show interfaces command for the FlexWAN module might display “administratively down, line
protocol is down.”
Workaround: Enter the shutdown and no shutdown commands for the affected interfaces. This
problem is resolved in Release 12.1(6)E. (CSCds86384)
• Flows between an Ethernet interface configured with an HSRP standby IP address and a WAN
interface might not be Layer 3 switched. This problem is resolved in Release 12.1(8a)E.
(CSCds66364)
• FlexWAN module crashinfo files do not propagate to the MSFC bootflash device.
Workaround: Display the FlexWAN module crashinfo filename with the dir
cwanslot_number/port_adapter_number-bootflash: command. You can copy a FlexWAN module
crashinfo file with the copy cwanslot_number/port_adapter_number-bootflash: command. This
problem is resolved in Release 12.1(14)E. (CSCdr71603)
• If you enable and disable MMLS on ATM subinterfaces with a combination of point-to-point and
multipoint subinterfaces, multicast shortcuts may not be created for multipoint connections, or in
some cases multicast traffic may fail. (CSCdr01409)
Note CSCdr01409 is not seen in later releases.
