Release Notes for Cisco IOS Release 12.0 S

78-7130-11 Rev. B0

Caveats

• CSCds30456

Entering the shutdown interface configuration command followed by the no shutdown interface

configuration command on a Gigabit Ethernet Interface Processor (GEIP) may cause an “output

stuck” condition and a complex restart. There is no workaround.

Resolved Caveats—Cisco IOS Release 12.0(14)S

All the caveats listed in this section are resolved in Cisco IOS Release 12.0(14)S. This section describes

only severity 1 and 2 caveats.

Basic System Services

• CSCdr52856

Enabling Multiprotocol Label Switching Traffic Engineering (MPLS TE) tunnels on a Cisco 7507

router might result in a memory leak by the interprocess communication (IPC) Seat Manager

process and a reload of the router if NetFlow and NetFlow Export are enabled on the router and the

NetFlow Export packets are going out of the MPLS-TE tunnels.

Workaround: Disable NetFlow Export by entering the no ip flow-export ip-address udp-port

global configuration command.

• CSCds25135

A Cisco Route Switch Processor 8 (RSP8) might reload at boot time because of an unexpected

exception if a boot host tftp:[[[//host]/directory-path]/filename] configuration command is present

in the startup configuration.

Workaround: Change the URL syntax in the configuration command to use the IP address instead

of the host name. For example, use boot host tftp:[[[//a.b.c.d]/directory-path]/filename].

• CSCds33629

A Cisco 12000 series Gigabit Switch Router (GSR) that is running the gsr-p-mz image of

Cisco IOS Release 12.0(9.1)S might reload in telnetBLOCK() while closing an existing Telnet

session. There is no workaround.

• CSCds34304

A Cisco 7500/RSP series router might experience a software-forced reload when fair queueing is

configured on more than 512 interfaces. There is no workaround.

• CSCds41795

A Cisco AS5800 series universal access server may experience a bus error at les_ipfib_flow_switch

along with spurious interrupts at the same process.

Workaround : Disable flow switching by entering the no ip route-cache flow interface

configuration command.

• CSCds58988

A Cisco 7507 or 7513 router with dual Route Switch Processor 2s (RSP2s), RSP4s, RSP4+s or

RSP8s, that is running any version of Cisco IOS between Cisco IOS Release 12.0(12.6)S and

Cisco IOS Release 12.0(13.6)S1 inclusive, might reload repeatly during bootup and fail to boot. In

this situation, messages similar to the following are displayed:

SLOT 7 RSP is system master SLOT 6 RSP is system slave RSP4 platform with 131072 Kbytes

of main memory
