Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• With Supervisor Engine 2, when a DVMRP unicast packet (for example, an MRINFO packet) enters
the switch to be routed, the packet is replicated multiple times. The number of replications depends
on the IP TTL value of the incoming packet. This problem is resolved in Release 12.1(8b)E6.
(CSCdv62588)
• With Supervisor Engine 1, after entering the no mls ip and mls ip interface commands on an
interface with multiple HSRP groups configured, some packets get switched in software on the
MSFC. This problem is resolved in Release 12.1(8b)E6. (CSCdv62673)
• When configured to run OSPF, the MSFC might wrongly populate the OSPF router routing table
with an entry corresponding to the MSFC itself, which can cause the MSFC to send a redundant
Type-4 LSA. This problem is resolved in Release 12.1(8b)E6. (CSCdu40792)
• Redistributing OSPF default routes to RIP with a route map might produce incorrect results. This
problem is resolved in Release 12.1(8b)E6. (CSCdu35038)
• An MSFC configured to support Data-Link Switching (DLSw) Ethernet redundancy might reload if
the connection to an upstream device is lost. Examples of an upstream device include a router
implementing SNA Switching Services (SNASw), a router with a connection to a mainframe
through a Channel Interface Processor (CIP), or a Channel Port Adapter (CPA). This problem is
resolved in Release 12.1(8b)E6. (CSCdu43189)
• ATM virtual circuits configured on an ATM port adapter in a FlexWAN module do not come up
following an MSFC reload. This problem is resolved in Release 12.1(8b)E6. (CSCdu56182)
• When an MSFC is in the HSRP standby state, it incorrectly responds to the ARP_Request sent from
an HSRP router in the Active state to a remote network beyond the MSFC in the HSRP standby state.
This problem is resolved in Release 12.1(8b)E6. (CSCdv24926)
• CPU utilization increases incorrectly when any SLB virtual server or firewall farm is brought into
service. This problem is resolved in Release 12.1(8b)E6. (CSCdv30472)
• When Internet Key Exchange (IKE) keepalive are not used, IPsec security associations are deleted
when the IKE security association gets deleted. This is a change in Cisco IOS operation and causes
backward compatibility issues with older versions, because IPsec security associations are up on the
device using an older version. This problem is resolved in Release 12.1(8b)E6. (CSCdu37163)
• With MSFC2, when you enter the ip forward-protocol turbo-flood command and the
ip forward-protocol spanning-tree command to forward UDP broadcasts on bridged interfaces,
the forwarded packets on the lowest-numbered VLAN are corrupted. Other forwarded packets are
not affected. This problem is resolved in Release 12.1(8b)E6. (CSCdv72780)
• A FlexWAN module might reload because of a spurious memory access at the
hqf_cwpa_pak_enqueue_local process. This problem is resolved in Release 12.1(8b)E6.
(CSCdu80042)
• Entering the show ip cef exact-route command at the transmit end of a MultiProtocol Label
Switching (MPLS) Traffic Engineering (TE) tunnel might cause the MSFC2 to reload. This situation
occurs when the destination prefix is recursive and the MSFC2 is load sharing to the next hop. This
problem is resolved in Release 12.1(8b)E6. (CSCdt80914)
• An RPF check incorrectly prefers BGP over MBGP when both tables have the same match route and
there is no BGP or MBGP distance configured. This problem is resolved in Release 12.1(8b)E6.
(CSCdv47188)
• A BGP route reflector is not advertising a MBGP route correctly. This problem is resolved in
Release 12.1(8b)E6. (CSCdv35791)
• The switch might reload if you use the range keyword to enter the switchport command. This
problem is resolved in Release 12.1(8b)E6. (CSCdv17531)
