Introduction
The goal of this document is to provide a concise list of useful commands to be used in the ACI environment. For in-depth information regarding these commands and their uses, please refer to the ACI CLI Guide.
Please note that legacy style commands (show firmware, show version, etc) will not be included in this guide. The below commands are new for ACI. Legacy commands may be added later on, but the point of this document is to be short and sweet.
Formatting
This document is formatted in the following way: commands are surrounded by <> in bold and possible user-given arguments within commands (if necessary) are surrounded by () with a | in between multiple arguments. Brackets [] will be used for mandatory verbatim arguments. A dash (-) will be the barrier between a command and the explanation for a command. For example:
<show interface (interface ID)> - shows the status of a given interface as well as statistics
interface ID is in () because it is a user-specified argument, you can put any interface you want
<show platform internal [ns|alp] mac asic [0|1]> - show the MAC port status
ns|alp and 0|1 are in brackets because you must use either one of those arguments
Command Completion and Help
Context sensitive help and command completion in ACI is a bit different than in other command line interfaces from Cisco. Since iShell builds mostly on Bash, these features tend to build off of the standard bash Programmable Completion feature.
- Tab - Use the tab key to auto complete commands. In cases where there are multiple commands that match the typed characters, all options should be displayed horizontally.
Example Usage:
admin@tsi-apic1-211:~> mo<Tab> moconfig mocreate modelete modinfo modprobe modutil mofind moprint more moset mostats mount mount.fuse mount.nfs mount.nfs4 mountpoint mountstats mount.tmpfs admin@tsi-apic1-211:~> mo
This is more than just iShell, it includes all Bash commands. Hitting Tab before typing any CLI command on the APIC results in:
admin@tsi-apic1-211:~> <Tab> Display all 1430 possibilities? (y or n)
- Esc Esc - Use Double escape to get context sensitive help for available ishell commands. This will display short help for each command. [Side note: In early beta code, Double Escape after typing a few characters would only show one of the matching commands rather than all of them. This is addressed via CSCup27989
]
Example Usage:
admin@tsi-apic1-211:~> <Esc><Esc> attach Show a filesystem object auditlog Display audit-logs controller Controller configuration create create an MO via wizard diagnostics Display diagostics tests for equipment groups dn Display the current dn eraseconfig Erase configuration, restore to factory settings eventlog Display event-logs fabricnode Commission/Decommission/Wipeout a fabric node faults Display faults firmware Add/List/Upgrade firmware health Display health info loglevel Read/Write loglevels man Show man page help moconfig Configuration commands mocreate Create an Mo modelete Delete an Mo [snip] admin@tsi-apic1-211:~>
- man <command> - All commands should have man pages. [Side note: If you find an iShell command without a man page - open a bug] The manual page for the commands will give you more detailed info on what the commands do and how to use them.
