RBMTX-Viper Watchcat
The Watchcat page of RBMTX-Viper router is used to set several checks and actions to take in the event that a host becomes unreachable. These rules will govern how this device reacts to network events. You can add here the rules for SIM cards switching (from SIM1 to SIM2 and back, delays, ping timeouts etc.).

In Ping Reboot mode, it defines the longest period of time without a reply from the Host To Check before a reboot is engaged. In Network Restart mode, it defines the longest period of time without a reply from the Host to Check before the interface is restarted. The default unit is seconds, without a suffix, but you can use the suffix m for minutes, h for hours or d for days. Examples: 10 seconds would be: 10 or 10s 5 minutes would be: 5m 1 hour would be: 1h 1 week would be: 7d | |
| Host To Check | IPv4 address or hostname to ping. | |
| Check Interval | How often to ping the host specified above.
The default unit is seconds, without a suffix, but you can use the suffix m for minutes, h for hours or d for days. Examples: 10 seconds would be: 10 or 10s 5 minutes would be: 5m 1 hour would be: 1h 1 week would be: 7d | |

| Force Reboot Delay | number, default: 30 | Applies to Ping Reboot and Periodic Reboot modes
When rebooting the router, the service will trigger a soft reboot. Entering a non-zero value here will trigger a delayed hard reboot if the soft reboot were to fail. Enter the number of seconds to wait for the soft reboot to fail or use 0 to disable the forced reboot delay. |
| Interface | br-lan, eth0, wwan0, dhcp, gsm or lan, default: gsm | Interface to monitor and/or restart |
RBMTX-Viper router has the ability to run pre-configured script for switching the SIM cards from master (SIM1) to slave (SIM2) card in case one of them (poor signal strength, network not available etc.) is unavailable. To use this function set "Run script" in "Mode" section and "sim_switch.sh" in "Script to run" section. All other option can be configured as described above.
For example you can set SIM1 switching (interface name: elte-sim1) where after 5 minutes without ping of 8.8.8.8 server (checked at 10-second intervals), the device will switch to SIM2 card automatically:
Use "Save and apply" button to save the configuration.
