PoE Consumption Graph (Device)
This graph is a device-level graph that shows the PoE utilization of the device over time. The
graph is available for all PoE devices with full SNA support.
The graph is represented per unit, and you can select a number of units (from a single or
multiple stacks) to view simultaneously.
The data is shown as a number of watts (0 - the PoE capacity of the selected unit with the
highest capacity) with numbers and frequency of samples depending on the displayed time
scale:
• Last hour—60 samples (one every minute)
• Last day—24 samples (one every hour)
• Last week—7 samples (one every day)
• Last year—52 samples (one every week)
Traffic Graph (Bytes)
This graph is an interface-level graph that shows the total traffic on an interface in bytes over
time. The graph is available for all interfaces of devices with full SNA support and has
separate lines for Tx and for Rx traffic.
You can select a number of ports and types of traffic to run a side-by-side comparison.
The data is shown as a number of octets (0 - highest sample in selected interfaces/time period)
with number and frequency of samples depending on the displayed time scale:
• Last five minutes—20 samples (one every 15 seconds).
• Last hour—60 samples (one every minute)
• Last day—24 samples (one every hour)
• Last week—7 samples (one every day)
• Last 3 months—12 samples (one every week)
Traffic Graph (Packets)
This graph is an interface-level graph that shows the total traffic on an interface in packets
over time. The graph is available for all interfaces (ports or LAGs) of devices with full SNA
support.
