OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
• CSCeb70755
Symptoms: Sporadic error recovery may occur on an Engine 4 plus (E4+) line cards after a corrupt
packet that comes from the fabric is detected. The error recovery is indicated by
%TX192-3-PAM_MODULE and %TX192-3-PAM_PIM error messages on the E4+ line card. The
packets are corrupted by Engine 3 line cards and are triggered by routing convergence.
Conditions: This symptom is observed on a Cisco 12416 router that runs Cisco IOS
Release 12.0(25)S or Release 12.0(25)S1. Only packets in the IP-to-tag path are affected.
Workaround: There is no workaround.
• CSCeb73894
Symptoms: You may not be able to load a Cisco IOS software image onto a Cisco 12000 series from
an Advanced Technology Attachment (ATA) Flash disk, and one or more error messages similar to
the following may appear:
open(): Open Error = -13 loadprog: error - on file open boot: cannot load
"disk0:gsr-p-mz.120-24.S2"
open: read error...requested 0x4 bytes, got 0xffffffff trouble reading device magic
number loadprog: error - on file open boot: cannot load "disk0:gsr-p-mz.120-22.S3c"
Conditions: This symptom is observed when the ATA disk is formatted with one Cisco IOS software
image and also contains another Cisco IOS software image that you attempt to load onto the Cisco
12000 series.
Workaround: Enter the boot system tftp filename ip-address global configuration command,
dummy for the filename argument, and 10.1.1.1 for the ip-address argument. Note that this
command parses without errors, and then fails; the router may not appear to boot initially, but
eventually does so.
Further Problem Description: The symptom only affects a Cisco 12000 series RP. It does not affect
a Cisco 12000 series PRP.
• CSCeb87765
Symptoms: A line card may crash when a class is removed from a policy map and this policy map
is attached to two different interfaces that are configured as IPv6 interfaces.
Conditions: This symptom is observed on a Cisco 12000 series when the removed class is configured
for both WRED and traffic shaping.
Workaround: Do not attach the same service policy to two different IPv6 interfaces.
• CSCec07354
Symptoms: On dual Performance Route Processors (PRPs) in RPR+ mode, the secondary PRP may
not boot up. When you log into the PRP, it appears to be in the ROMmon state.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(25)S1 when the ROM monitor of the primary RPR is upgraded.
Workaround: Attach to the secondary RPR and boot up this RPR manually by entering the boot
command on the ROMmon prompt.
• CSCec08364
Symptoms: Ethernet over Multiprotocol Label Switching (EoMPLS) packet forwarding may stop.
Conditions: This symptom is observed when you configure an IP address on the EoMPLS interface.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the EoMPLS interface.
