Information About Displaying ACE Hardware and Software Information
The ACE CLI provides a comprehensive set of show commands in Exec mode that you can use to gather the following system information:
•Installed hardware and software information
•System processes
•System information
•Technical support
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. For background information about theose show commands, see the Cisco Application Control Engine Module Command Reference.
Displaying Hardware Information
To display ACE hardware information, perform one of the following tasks:
Command
|
Purpose
|
show hardware
|
Displays the ACE hardware details.
|
show inventory [raw]
|
Displays the system hardware inventory of the ACE. This command displays information about the field replaceable units (FRUs) in the ACE, including product identifiers, serial numbers, and version identifiers.
The optional raw keyword displays information about each temperature sensor in the ACE.
|
show dc dc_number console
|
Displays whether the the master or the slave network processor console is directed to the base board front panel for the specified daughter card. For example, if the master network processor is directed to the front panel, the following message appears: "mCPU console is directed to base board front panel." See the related set dc dc_number console command.

•internal—Displays Cisco internal system-related functions. The internal keywords and related keywords, options, and arguments are intended for use by trained Cisco personnel for troubleshooting purposes only. This option is available in the Admin context only.
•kcache—Displays the Linux kernel cache statistics..
•kmem—Displays the Linux kernel memory usage.
•kmemtrack—Displays the kernal memory allocations in the kernel loadable modules. This keyword is intended for use by trained Cisco personnel for troubleshooting purposes only.
•resources—Displays system-related CPU and memory statistics.
•skbtrack—Displays the socket buffer (network buffer) allocations in the kernel loadable modules. This keyword is intended for use by trained Cisco personnel for troubleshooting purposes only.
•uptime—Displays how long the ACE has been up and running. This keyword is available in all user contexts.
•watchdog [lcp | memory | scp]—Displays whether the watchdog is enabled or disabled. When the watchdog is enabled, its timeout is displayed. When you enter this keyword without an option, all watchdogs are displayed. To display a specific watchdog, enter one of the following options:
–lcp—LCP process watchdog. The current SCP watchdog watches this process. However, if the LCP process is not scheduled on time, this watchdog reboots the ACE.
–memory—Low memory watchdog when the ACE memory reaches 99 percent.
–scp—Watchdog for SCP keepalive messages from the hardware timer interrupt level.
The system watchdog memory command allows you to configure the Memory watchdog timeout. The LCP and SCP timeouts are not configurable.

|
Available Linux kernel RAM.
|
Shared
|
Always zero.
|
Buffers
|
Memory in buffer cache.
|
Cached
|
RAM used for the page cache (disk cache) minus the RAM used for the swap cache.
|
Swap
|
Total
|
Total amount of physical swap memory.
|
Used
|
Total swap memory in use.
|
Free
|
Available swap memory.
|
MemTotal
|
Total usable Linux kernel RAM (physical RAM minus the reserved bits and the kernel binary code).
|
MemFree
|
Available Linux kernel RAM.
|
MemShared
|
Always zero.
|
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 or Collecting Technical Information for Reporting Problems
To display or collect general information about the ACE for use when reporting a problem, perform one of the following tasks:
Command
|
Purpose
|
show tech-support [details]
|
Displays general information about the ACE for use when you report a problem. You can use this command to collect a large amount of information about your ACE and provide the command output to technical support representatives.
This command displays the output of several show commands at once. The command output varies depending on your configuration.
The optional details keyword provides detailed information for each show command.
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.
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 General System Process Information" section
•show running-config—See Chapter 4, Managing the ACE Software
•show version—See the "Displaying Installed Software Information" section
When using this command, 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).
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.

|
tac-pac {disk0:[path/]filename | {ftp://server/path[/filename] | scp://[username@]server/path[/filename] | sftp://[username@]server/path[/filename] | tftp://server[:port]/path[/filename]}
|
Redirects the same information as the show tech-support command output to a file on either the ACE disk0: or a remote server.
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.
•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, optionally, the filename.
•tftp://server[:port]/path[/filename]—Specifies the TFTP network server and, optionally, the filename.
The output of the show tech-support 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.
