Brocade FastIron Ethernet Switch Administration Guide - Manual (Page 260)

The num parameter specifies the list number. You can configure up to four lists. Specify a number
from 1 - 4.
The uplink ethernet parameters and the port numbers you specify after the parameters indicate the
uplink ports.
The downlink ethernet parameters and the port numbers you specify after the parameters indicate
the downlink ports.
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 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 packets relative to the total number of packets on the uplink.
To display an uplink utilization list, enter a command such as the following at any level of the CLI.
device#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-utilizationnum
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.
device#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. In this example, port
1/2 is connected to a hub and is sending traffic to port 1/1. Port 1/3 is unconnected.
device#show relative-utilization 1
uplink: ethe 1
30-sec total uplink packet count = 2996
packet count ratio (%)
1 /2:100 1/ 3:---
