Utilization list for an uplink port 11

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 1/1/2 and 1/1/3 are sending traffic to port 1/1/1. Port 1/1/2 and port 1/1/3 are isolated (not shared by multiple clients) and typically do not exchange traffic with other ports except for the uplink port, 1/1/1.

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 1/1/2 and 1/1/1, and by ports 1/1/3 and 1/1/1. 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 1/1/2 and 1/1/3 are in the same port-based VLAN.

Brocade#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 1/1/2 is connected to a hub and is sending traffic to port 1/1/1. Port 1/1/3 is unconnected.

Brocade#show		relative-utilization 1
uplink: ethe		1
30-sec	total	uplink packet count = 2996
packet	count	ratio (%)
1 /2:100		1/ 3:---
