SMON Overview
VLAN Statistics Overview
The VLAN Statistics tool measures the switched traffic travelling through
VLANs on the selected switch. A VLAN consists of stations connected
logically rather than physically. A VLAN can be used, for example, to
distribute network resources by department, even if the departments
stations are not all located in the same area. Therefore, a VLAN can
incorporate stations from different devices.
By comparing the load of each VLAN you can discover which VLANs are:
Utilizing their full capacity.
Under capacity.
Over-extended and probably causing a degradation in performance
to the users.
VLAN Statistics represents the information as a horizontal bar chart. Using
this tool in conjunction with Port Statistics and Switch Statistics makes it
straightforward to discover the cause of a problem. For example, using
VLAN Statistics you may discover that there are too many broadcast
errors on a specific VLAN. You could then use Port Statistics to help
indicate from which port the problem originates.
Alarms and Events Overview
The Alarms and Events tool reports when a specified counter on selected
ports, or on a device, cross user defined thresholds. The Alarm Wizard
provides a simple method for defining upper and lower thresholds of a
counter on selected ports or on the device. This definition of the
thresholds is an Alarm.
An Event is the crossing of a defined threshold in the direction it was
defined. For example, a Rising Event is when the rate of a specified
counter on a selected port rises above the defined Rising (upper)
Threshold. A Falling Event is when the rate of a specified counter on a
selected port falls below the defined Falling (lower) Threshold.
