Displaying Utilization Percentages for an Uplink
After you configure an uplink utilization list, you can display the list to observe the percentage of the uplink’s
bandwidth that each of the downlink ports used during the most recent 30-second port statistics interval. The
number of packets sent and received between the two ports is listed, as well as the ratio of each individual
downlink port’s packets relative to the total number of packets on the uplink.
To display uplink utilization percentages, use either of the following methods.
USING THE CLI
To display an uplink utilization list, enter a command such as the following at any level of the CLI:
HP9300(config)# show relative-utilization 1
uplink: ethe 1
30-sec total uplink packet count = 3011
packet count ratio (%)
1/ 2:60 1/ 3:40
In this example, ports 1/2 and 1/3 are sending traffic to port 1/1. Port 1/2 and port 1/3 are isolated (not shared by
multiple clients) and typically do not exchange traffic with other ports except for the uplink port, 1/1.
Syntax: show relative-utilization <num>
The <num> parameter specifies the list number.
NOTE: The example above represents a pure configuration in which traffic is exchanged only by ports 1/2 and
1/1, and by ports 1/3 and 1/1. For this reason, the percentages for the two downlink ports equal 100%. In some
cases, the percentages do not always equal 100%. This is true in cases where the ports exchange some traffic
with other ports in the system or when the downlink ports are configured together in a port-based VLAN.
In the following example, ports 1/2 and 1/3 are in the same port-based VLAN.
HP9300(config)# show relative-utilization 1
uplink: ethe 1
30-sec total uplink packet count = 3011
packet count ratio (%)
1/ 2:100 1/ 3:100
Here is another example showing different data for the same link utilization list.
connected to a hub and is sending traffic to port 1/1. Port 1/3 is unconnected.
HP9300(config)# show relative-utilization 1
uplink: ethe 1
30-sec total uplink packet count = 2996
packet count ratio (%)
1 /2:100 1/ 3:---
In this example, port 1/2 is
2 - 28
