Configuring the Watchdog Features
Accessing Watchdog Configuration Mode
The
service sw-watchdog
command, in Global Configuration mode, enables access to Watchdog
Configuration mode and its configuration options.
Command Syntax
device-name
(config)#
service sw-watchdog
device-name
(sw-watchdog)#
Setting the Reset-Loop Detection
The
sw-watchdog system reset-loop
command, in Watchdog Configuration mode, enables the
Reset-Loop Detection, sets the reset loop detection time period and specifies the interface to be
used as the maintenance port when reset loop is detected. The
no
form of the
command disables
the Reset-Loop Detection and prevents the system from being monitored for reset loops.
When the Reset-Loop Detection is enabled, the Watchdog detects when a reset-loop occurs and
logs a notification about it to the NVRAM. The device is considered to be in a reset loop when it
resets more than 3 times within a specified time period. If a reset loop is detected, the device
reverts to a state in which all LAN ports, except for the one configured as maintenance port, are
kept in physically disabled state.
By default, the Reset-Loop Detection is disabled.

Argument Description

device will be considered to be in a reset loop. The range is <30-1500>
seconds.
