Utilization list for an uplink port
11
Each uplink utilization list consists of the following:
• Utilization list number (1, 2, 3, or 4)
• One or more uplink ports
• One or more downlink ports
Each list displays the uplink port and the percentage of that port bandwidth that was utilized by the
downlink ports over the most recent 30-second interval.
You can configure up to four bandwidth utilization lists.
Utilization list for an uplink port command syntax
To configure an uplink utilization list, enter commands such as the following. The commands in this
example configure a link utilization list with port 1/1 as the uplink port and ports 1/2 and 1/3 as
the downlink ports.
Brocade(config)#relative-utilization 1 uplink eth 1/1 downlink eth 1/2 to 1/3
Brocade(config)#write memory
Syntax: [no] relative-utilization num uplink ethernet port [to port | port…] downlink ethernet port
[to port | [port…]
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.
Brocade#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.
