Using the CLI

Syntax:

By default, the show logging command displays the log messages recorded since the last reboot in chronological order:

`-a`	Displays all recorded log messages, including those before the last reboot.
`-b`	Displays log events as the time since the last reboot instead of in a date/time format.
`-r`	Displays all recorded log messages, with themost recent entries listed first (reverse order).
`-s`	Displays the active management module (AM) and standby management module (SM) log events.
`-t`	Displays the log events with a granularity of 10 milliseconds.
`-m`	Displays only major log events.
`-e`	Displays only error event class.
`-p`	Displays only performance log events.
`-w`	Displays only warning log events.
`-i`	Displays only informational log events.
`-d`	Displays only debug log events.

`filter`	Displays only log filter configuration and status information.
`<option-str>`	Displays all Event Log entries that contain the specified text. Use an `<option-str>`value with `-a` or `-r` to further filter `show logging` command output.

Example:

To display all Event Log messages that have "system" in the message text or module name, enter the following command:

switch# show logging -a system

To display all Event Log messages recorded since the last reboot that have the word "system" in the message text or module name, enter:

switch# show logging system
