Viewing ACE Hardware and Software Configuration Information
This chapter describes how to view Cisco 4700 Series Application Control Engine (ACE) appliance hardware and software configuration information. The ACE CLI provides a comprehensive set of show commands in Exec mode that you can use to gather ACE hardware and software configuration information.
This chapter contains the following major sections:
•

•Displaying Software Copyright Information
•Displaying Hardware Information
•Displaying the Hardware Inventory
•Displaying System Processes
•Displaying Process Status Information and Memory Resource Limits
•Displaying System Information
•Displaying ICMP Statistics
•Displaying Technical Support Information
To view the contents of the current running-configuration file and startup-configuration file, see Chapter 4, Managing the ACE Software.
Note The show buffer, show fifo, show netio, show np, and show vnet commands display internal system-level hardware show output for use by trained Cisco personnel as an aid in debugging and troubleshooting the ACE. See the Cisco 4700 Series Application Control Engine Appliance Command Reference for background information about those show commands.
Displaying Software Version Information
To display the version of system software that is currently running on the ACE in Flash memory, use the show version command. You use the show version command to verify the software version on the ACE before and after an upgrade.
The syntax of this command is:
show version
For example, to display the entire output for the show version command, enter:
host1/Admin# show version

Displaying Technical Support Information
To display general information about the ACE when you report a problem, use the show tech-support command in Exec mode. You can also use this command to collect a large amount of information about your ACE and provide the output of this command to technical support representatives when you report a problem.
The show tech-support command displays the output of several show commands at once. The output from this command varies depending on your configuration.
You can choose to have detailed information for each command or even specify the output for a particular interface or appliance. Each command output is separated by the line and the command that precedes the output.
Note Explicitly set the terminal length command to 0 (zero) to disable autoscrolling and enable manual scrolling. Use the show terminal command to view the configured terminal size. After obtaining the output of this command, reset your terminal length as required (see Chapter 1, Setting Up the ACE).
Note You can save the output of this command to a file by appending > filename to the show tech-support command (see Chapter 4, Managing the ACE Software). If you save this file, verify that you have sufficient space to do so; each file may take about 1.8 MB.
The default output of the show tech-support command includes the output of the following commands:
•show hardware—See the "Displaying Hardware Information" section
•show interface—See the Cisco 4700 Series Application Control Engine Appliance Routing and Bridging Configuration Guide
•show process—See the "Displaying System Processes" section
•show running-config—See the Chapter 4, Managing the ACE Software
•show version—See the "Displaying Software Version Information" section
The syntax of this command is:
show tech-support [details]
The optional details keyword provides detailed information for each show command.
For example, to display an excerpt of the current running state of the ACE, enter:
host1/Admin# show tech-support

To redirect the output of the show tech-support command to a file to the disk0: file system on the ACE or to a remote server using File Transfer Protocol (FTP), Secure Copy Protocol (SCP), Secure Transfer Protocol (SFTP), or Trivial Transfer Protocol (TFTP), use the tac-pac command in Exec mode.
Note The output of the tac-pac command is in gzip format. We recommend that you include the .gz extension in the filename so that it can be easily unzipped from the destination filesystem.
The syntax of this command is:
tac-pac {disk0:[path/]filename | ftp://server/path[/filename] |
scp://[username@]server/path[/filename] |
sftp://[username@]server/path[/filename] |
tftp://server[:port]/path[/filename]}
The keywords, arguments, and options are:
•disk0:[path/]filename—Specifies that the file destination is the disk0: file system of the current context. If you do not provide the optional path, the ACE copies the file to the root directory on the disk0: file system.
•ftp://server/path[/filename]—Specifies the FTP network server and optional file name.
•scp://[username@]server/path[/filename]—Specifies the SCP network server and optional file name.
•sftp://[username@]server/path[/filename]—Specifies the SFTP network server and optional file name.
•tftp://server[:port]/path[/filename]—Specifies the TFTP network server and optional file name.
For example, to send the output of the show tech-support command to a remote FTP server, enter:
host1/Admin# tac-pac ftp://192.168.1.2/tac-output_7-7-08.gz
