Stack monitor
The Stack Monitor uses a set of control values to enable its operation, to
set the expected stack size, and to control the frequency of trap sending.
The stack monitor, if enabled, detects problems with the units in the stack
and sends a trap.
The stack monitor sends a trap for the following events.
•
The number of units in stack changes.
•
The trap sending timer expires.
Each time the number of units in a stack changes, the trap sending timer
resets and the stack monitor compares the current number of stack units
with the configured number of stack units. If it is not equal, the switch sends
a trap and logs a message to syslog. The stack monitor sends traps from
a standalone unit or the base unit of the stack.
When the trap sending timer reaches the configured number of seconds at
which traps are sent, the switch sends a trap and logs a message to syslog
and restarts the trap sending timer. The syslog message is not repeated
unless the stack configuration changes. This prevents the log being filled
with stack configuration messages.
When you enable the stack monitor on a stack, the stack monitor captures
current stack size and uses it as the expected stack size. You can choose a
different value and set it after enabling the feature.
