The "TBC0719017300000" string is the rack number. This string should be present for every chassis.
The number is burnt in by manufacturing.
Using ping and traceroute
For details on the ping and traceroute commands, see the “Basic Troubleshooting Commands” section
inCisco IOS XR Getting Started Guide for the Cisco CRS-1 Router.
Using Debug Commands

Using Diagnostic Commands
The Cisco IOS XR diagnostic tests verify control Ethernet and fabric data paths between nodes in a
system using Cisco IOS XR software. If a diagnostic tests fails, it indicates a bad data path. The integrity
of the covered data paths is verified when the diagnostic tests pass.
The system runs diagnostic tests automatically to verify control Ethernet and fabric data paths between
nodes in the system. The integrity of the covered data paths is verified when the diagnostic tests pass. If
a diagnostic tests fails, it indicates a bad data path and the system alerts you to the problem.
The diagnostic tests generally test data paths between multiple nodes, therefore you need to analyze error
reports to narrow down the possible points of failure in a system. For example, if a diagnostic test fails
on a fabric interface, the fabric cables in the path of failure would be a primary suspected cause of the
failure.
All diagnostic tests run within the 1 second to 1 minute range.
This section contains the following additional topics related to diagnostics:
• Online Diagnostics, page 7-166
• Transient Condition when Standby RP Becomes Active, page 7-168
• Offline Diagnostics—FDIAG RUNNING State, page 7-169
• Additional Reference for Diagnostic Commands, page 7-169
Online Diagnostics
You can start and stop diagnostic tests on specific nodes while the node is online and processing traffic.
It is important to run test on both the active and standby RP; the standby RP is actually capable of
running more fabric diagnostic tests than the active RP.
Examples:
The following example shows a set of diagnostic tests on the active RP (0/RP0/CPU0).
