Appendix C Using Technical Support - Cisco ONS 15454 SDH Configuration Manual

Getting the Data from Your ML-Series Card
•
To assist you in gathering this required data, the show tech-support EXEC command has been added in
Cisco IOS Release 11.1(4) and later. This command provides general information about the switch router
that you can provide to your technical support representative when you are reporting a problem.
The show tech-support command outputs the equivalent of the show version, show running-config,
show controllers, show stacks, show interfaces, show buffers, show process memory, and show
process EXEC commands.
The specific information requirements that might be needed by technical support vary depending on the
situation. They include the following:

Getting the Data from Your ML-Series Card
When obtaining the information from your ML-Series card, you must tailor your method to the system
that you are using to retrieve the information. Following are some hints for different platforms:

C-2
Node equipment and configuration; including type of cross-connect cards, ML-Series cards' slot
numbers, OC-N cards, and TCC2/TCC2P cards.
Output from the following general show commands:
show interfaces
show controllers
show processes {cpu | mem}
show buffer
show mem summary
Output from the following protocol-specific show commands:
show protocol route
show protocol traffic
show protocol interfaces
show protocol arp
Output from provisioning show commands
Output from relevant debug privileged EXEC commands
Output from protocol-specific ping and trace diagnostic tests, as appropriate
Network analyzer traces, as appropriate
Core dumps obtained using the exception dump command, or using the write core command if the
system is operational, as appropriate
PC and Macintosh—Connect a PC or Macintosh to the console port of the ML-Series card and log
all output to a disk file (using a terminal emulation program). The exact procedure varies depending
on the communication package used with the system.
Terminal connected to the console port or remote terminal—The only way to get information with
a terminal connected to the console port or with a remote terminal is to attach a printer to the AUX
port on the terminal (if one exists) and to force all screen output to go to the printer. Using a terminal
is undesirable because there is no way to capture the data to a file.
