Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• The IPX rip-response-delay interface command does not work on an MSFC, which prevents
configuration of preferred routes with this command. (CSCdr45398)
Note This problem has not been seen in later releases.
• The MSFC2 does not support the MultiNode Load Balancing (MNLB) forwarding agent of the
MNLB feature set for LocalDirector. This problem is resolved in Release 12.1(8a)E. (CSCdr65433)
• The ciscoFlashDeviceInitTime CISCO-FLASH-MIB object does not return the correct device
initialization (insertion or removal) timestamp for the Flash devices on a redundant supervisor
engine. Users of applications that depend on ciscoFlashDeviceInitTime should take care not to
remove a redundant supervisor engine or a PCMCIA card from slave-slot0:when the applications
are performing Flash file operations. This problem is resolved in Release 12.1(11b)E.
(CSCdp98597)
• Downloading images to an Intel Value series 200 Flash card in the PCMCIA slot may in rare
situations fail to write a valid image. Downloading during periods of low system activity reduces the
likelihood of this failure. This problem is resolved in Release 12.1(6)E (see the related
Release 12.0(7)XE1 resolved CSCdm52806 caveat). (CSCdm52806)
• A traceback message displays when you exit the switch console. This message is harmless and can
be safely ignored. This problem is resolved in Release 12.1(8a)E. (CSCdp35517)
Resolved Caveats in Release 12.1(4)E1
• After you enter the no mls qos flow-policing and mls qos flow-policing commands, any microflow
policing previously configured on interfaces is not restored. To recover, either remove the service
policies that have microflow policing and then reapply them, or enter the shutdown command and
then the no shutdown command on the interfaces. This problem is resolved in Release 12.1(4)E1.
(CSCds41316)
• For 48-port 10/100TX RJ-45 Ethernet switching modules (WS-X6248-RJ-45), the output from the
show queueing interface command does not contain the “Packets dropped on Transmit” section or
the “Packets dropped on Receive” section. This problem is resolved in Release 12.1(4)E1.
(CSCds39365)
• When an interface configured as a switch port has both an IGMP receiver and a multicast-capable
router attached to it, IGMP snooping incorrectly marks the port as only a multicast router port,
which disrupts traffic to the multicast receiver if the multicast router attached to the interface goes
down. This disruption lasts until IGMP snooping learns the port correctly. In the worst case, the
disruption lasts for the IGMP query interval. This problem is resolved in Release 12.1(4)E1.
(CSCds54124)
• For a multicast source directly connected to a router, the “R” flag may get set when receiving an
(S,G,R) prune if the (S,G) O-list is NULL, and the prune is received on the non-incoming interface
(nonIIF). This situation causes the IIF to change to the route processor (RP), and causes the IIF to
no longer be the rendezvous point (RP) directly connected to the source, which resets the “F” flag.
The RP then loses the (S,G) state and new receivers cannot join the multicast source. This problem
is resolved in Release 12.1(4)E1. (CSCds23901)
