Release Notes for Cisco IOS Release 12.0 S

78-7130-11 Rev. B0

Caveats

EXEC and Configuration Parser

• CSCdr53609

Deleting one serial subinterface from the running configuration on a Cisco 7500/RSP series router

with a Route Switch Processor 4 (RSP4) that is running Cisco IOS Release 12.0(9)S or

12.0(10.3)S1 will cause the whole interface to disappear.

Workaround: Add the interface that was deleted back to the configuration.

Interfaces and Bridging

• CSCds12978

On a Cisco 7200 series router, the High-Level Data Link Control (HDLC) encapsulated interface

on a Packet-Over-SONET (POS) port adapter is never up after reloading unless you configure the

cdp enable or clock source internal interface configuration commands.

Workaround: Use the clear interface EXEC command or a sequence of the shut and no shut

interface commands.

IP Routing Protocols

• CSCdr49641

A Cisco router that is running Cisco IOS Release 12.0(10)S and receives a large packet that was

fragmented before receipt might display the following error message at the rendezvous point of a

multicast network that is running PIM sparse mode:

%PIM-5-REG_ENCAP_INVALID: Bad register from <IP-address> for (<IP-address>,

<Class-D-IP-address>). Trace = ....

There is no workaround.

• CSCdr68435

If the set interface route-map configuration command is entered on a Cisco router that is using

distributed policy routing, the subinterfaces do not function properly, and the command will not

work on an interface that is on a different line card.

Workaround: Enter the set ip next-hop route-map configuration command rather than the set

interface command.

• CSCdr88511

A Cisco router that is running Cisco IOS 12.0(10.6)S2 or later releases might not install default

routes that are advertised though type 5 link-state advertisements (LSAs) by other routers. This

condition occurs when the Cisco router has only type 5 default LSAs and no nondefault type 5

LSAs are present in the database.

Workaround: Add a nondefault external LSA to the database.

• CSCdr89108

Multicast distributed switching (MDS) does not function properly on ATM subinterfaces on

Cisco 7500/RSP series routers. Instead of being switched by the Versatile Interface Processor

(VIP), the multicast traffic in this situation will be sent to the Route Switch Processor (RSP) to be

switched by the RSP CPU.
