Release Notes for Cisco IOS Release 12.0 S

78-7130-11 Rev. B0

Caveats

• CSCdp78089

When the environmental values for voltage get corrupted and a Cisco 12008 Gigabit Switch Router

(GSR) has all slots at the critical warning level, entering the show run command causes the router

to shut down. This condition is more likely to occur after a router has been up and running for

several weeks or more. There is no workaround.

• CSCdp83870

Proper Multiprotocol Label Switching (MPLS) fragmentation is not done for some packet sizes on

a Cisco 12000 series gigabit switch router (GSR) when the output interface is Fast Ethernet (FE)

or Gigabit Ethernet (GigE). There is no workaround.

• CSCdp90558

When the atm pvp interface configuration command is entered on a Cisco 12000 Gigabit Switch

Router (GSR) that is running Cisco IOS Release 12.0(8.5)S or higher releases, two F4 Operation,

Administration, and Maintenance (OAM) virtual circuits (VCs) are automatically created. There is

no workaround.

• CSCdr02906

A Cisco router might experience spurious memory access in function lc_qos_supported() when the

show running-config command or the show startup-config command is entered and exhibit a

traceback similar to the following:

Reading rsp-jsv-mz.121-1.0.2.T.symbols rsp-jsv-mz.121-1.0.2.T.symbols read in Enter hex

This situation will occur if one or more Fast Ethernet channels are configured by entering the

interface port-channel command. There is no workaround.

• CSCdr04630

Packets that are destined to IP prefixes using recursive routes over Multiprotocol Label

Switching/traffic engineering (MPLS/TE) tunnels might be dropped by OC-48 Packet over SONET

(POS) and QOC-12 POS line cards for the Cisco 12000 series gigabit switch router (GSR) at the

head end of the tunnnel. There is no workaround.

• CSCdr08160

Under heavy traffic on the outbound side of a Spatial Reuse Protocol (SRP) port adapter, packets

will get queued on holdq if the TX ring is full. These packets will be accounted as process switched

instead of route-cache switched. There is no workaround.

• CSCdr15506

When 802.1Q is configured on a Cisco 12000 series gigabit switch router (GSR) Gigabit Ethernet

(GigE) line card, the following error message might be displayed:

%LC-3-BMACMDLOST: ToFab BMA has lost a command

There is no workaround.
