Troubleshooting the BPX Switch
System Troubleshooting Tools
You can perform a number of manually-initiated tests from the Cisco WAN Manager NMS console to
assist in system troubleshooting. These tests may be included in a job so they can be scheduled to run
remotely at a specified time if desired.
User-initiated Tests
Several user-initiated tests can be used to diagnose system problems. These tests are self-contained in
that they do not require the use of external test equipment. They also do not require you to place a
loopback at the far end to test both directions of transmission. These tests are listed in Table 29-3.
Several display commands can be used to obtain information that may be helpful in troubleshooting
system problems. These are also listed in Table 29-3.
Downloading
Software There are downloader commands that appear when the
system is down- loading software to the BCC.
Minor BCC Redundancy alarm indicates node is configured for
redundancy but no standby BCC is equipped.
1. Cards with an F status (no terminal failure) are activated only when necessary. Cards with a failed status are never
activated.
