ISR Status via SMS: Overview

This function of the ISR app provides a way to query the ISR for status. Any ISR “show”

command can be sent. Examples include displaying:

- The IP routing table (show ip route)

- The state and stats for any ISR interface (show interface)

- Log messages pertaining to a specific event or interface (e.g. show log | i Cellular)

- The ISR configuration, or a specific portion (e.g. show running interface Cellular0)

There is no need for ISR Web or command line access. A smart phone is all that is needed.

ISR Status via SMS: Details

Any enable mode command can be sent via text message. The script can be modified to only

allow certain commands or disable-mode commands to be entered. The script can be

modified to only allow non-IOS display commands (a command that is translated into actual

ISR commands), further controlling access or requesting output from multiple commands

via a single request. An example of the logic for this is available here:

Commands requiring a confirmation are handled by adding “;y” to the text message.
