Viewing ACE Hardware and Software Configuration Information
This chapter describes how to view ACE 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:
•

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 cde, show fifo, show hyp, show lcp, show netio, show np, show scp, 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 Application Control Engine Module 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 as follows:
show version
For example, to display the entire output for the show version command, enter:
host1/Admin# show version

Buffers
|
Memory in buffer cache.
|
Cached
|
RAM used for the page cache (disk cache) minus the RAM used for the swap cache.
|
SwapCached
|
Memory that once was swapped out, is swapped back in, but is still in the swap file. If this memory is needed, it does not need to be swapped out again because it is already in the swap file. This saves I/O.
|
Active
|
Memory that has been used recently and usually not reclaimed unless it is absolutely necessary.
|
Inactive
|
Memory that is unused or easily freeable.
|
HighTotal
|
Total amount of memory in the high memory (highmem) region. Highmem is all memory above approximately 860 MB of physical RAM. The kernel uses indirect methods to access the high memory region. Data cache can go in this memory region.
|
HighFree
|
Total amount of available memory in the highmem area.
|
LowTotal
|
Amount of memory in the low memory region (non-highmem memory).
|
LowFree
|
Amount of free memory in the low memory region. The kernel can address low memory directly. All kernel data structures need to go into low memory.
|
SwapTotal
|
Total amount of physical swap memory.
|
SwapFree
|
Available swap memory.
|
Committed_AS
|
An estimate of how much RAM you would need to make a 99.99% guarantee that there never is an out-of-memory (OOM) condition for a particular workload. Normally, the kernel overcommits memory. For example, if you dynamically allocate 1 GB of memory, no demand is placed on that memory until you actually start using it. The Committed_AS is an estimate of how much RAM or swap memory you would need in a worst-case scenario.

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 module. 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 the "Configuring Terminal Display Attributes" section in 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, for example, the output of the following commands:
•show hardware—See the "Displaying Hardware Information" section
•show interface—See the Cisco Application Control Engine Module Routing and Bridging Configuration Guide
•show process—See the "Displaying System Processes" section
•show running-config—See Chapter 4, Managing the ACE Software
•show version—See the "Displaying Software Version Information" section
The syntax of this command is as follows:
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 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 file system.
The syntax for the command is as follows:
tac-pac {disk0:[path/]filename | {ftp://server/path[/filename] |
sftp://[username@]server/path[/filename] |
tftp://server[:port]/path[/filename]}
The keywords, arguments, and options are as follows:
•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, optionally, the filename.
•sftp://[username@]server/path[/filename]—Specifies the SFTP network server and, optionally, the filename.
•tftp://server[:port]/path[/filename]—Specifies the TFTP network server and, optionally, the filename.
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_10-7-07.gz
