The pattern keyword is optional and is used only when the command
string solicits input. The action clicommand ends when the solicited
prompt as specified in the optional pattern keyword is received. You
are required to specify a regular expression pattern that will match
the next solicited prompt. Specification of an incorrect pattern will
Example:
Device(config-applet)# action 2.0 cli
cause the action cli command to wait forever until the applet
execution times out due to the maxrun timer expiration.
•
The action taken is to specify an EEM applet to run when the
pattern keyword specifies the confirm argument for the clear
command "clear counters Ethernet0/1" pattern
"confirm"
