Chapter 6 Troubleshooting the Installation
Advanced SIP Troubleshooting
Note The LED label may appear reversed in the show led command output. For example, IOS RUN may be
displayed as RUN IOS.
If the show led command on the SIP displays anything other than IOS RUN, or the RP is neither the
active Master/Primary nor the Slave/Secondary, there is a problem and the SIP has not fully loaded
correctly. Before replacing the SIP, try fixing the problem by following these steps:
Step 1 Reload the microcode using the global configuration microcode reload slot command.
Step 2 Reload the SIP using the hw-module slot reload command. This causes the SIP to reset and download
the MBus and fabric downloader software modules before attempting to download the Cisco IOS
software.
or
Reset the SIP manually. This may rule out any problems that are caused by a bad connection to the MBus
or switching fabric.
Fabric Ping Failure
Fabric ping failures occur when either a SIP or the secondary RP fails to respond to a fabric ping request
from the primary RP over the switch fabric. Such failures are a problem symptom that should be
investigated. They are indicated by the following error messages:
%GRP-3-FABRIC_UNI: Unicast send timed out (1)
%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure
%LCINFO-3-CRASH: Line card in slot 1 crashed
You can find more information about this issue on Cisco.com in the Troubleshooting Fabric Ping
Timeouts and Failures on the Cisco 12000 Series Internet Router document.
Error Messages
If you receive any error message related to a SIP, you can use the Error Message Decoder Tool (on
Cisco.com) to find the meaning of this error message. Some errors point to a hardware issue, while others
indicate a Cisco IOS software caveat or a hardware issue on another part of the router. This document
does not cover all these messages.
Note Some messages related to Cisco Express Forwarding (CEF) and Inter Process-Communication (IPC) are
explained on Cisco.com in the Troubleshooting CEF-Related Error Messages document.
