Deleting AL_PA members from trunk groups
(root/config/load/delalpa)
This command removes a specified AL_PA member from a trunk group. Once removed
from the trunk group, the AL_PA returns to using the primary trunk.
To delete an AL_PA member from a specific trunk group:
From the Load Balancing configuration menu (root/config/load), type
delalpa
<cascade port number> <AL_PA member>
and press E
NTER
.
Note: To delete multiple port members, use spaces or commas between port members.
Adding AL_PA members to trunk groups (root/config/load/addalpa)
This command sets the AL_PA members associated with a trunk group for load
balancing. Once assigned to a specific trunk group, the AL_PA uses the specified trunk
for all traffic flow.
To add an AL_PA member to a specific trunk group:
From the Load Balancing configuration menu (root/config/load), type
addalpa
<cascade port number> <AL_PA member>
and press E
NTER
.
Note: To add multiple port members, use spaces or commas between port members.
Displaying initiator AL_PAs (root/config/load/ialpa)
This command displays the AL_PAs that have been detected as initiators. This
information is useful when configuring load balancing.
To display Initiator AL_PA members:
From the Load Balancing configuration menu (root/config/load), type
ialpa
and press
E
NTER
.
Displaying port utilization (root/config/load/util)
Port utilization measures the amount of traffic running out of a port. For example, if an
initiator is transmitting data to a target, the initiator port displays a port utilization value
(%) while the target port does not. If the same initiator is receiving data from the target,
the target port displays a port utilization value (%) while the initiator port displays does
not.
The Port Utilization page displays port utilization for the latest completed intervals based
on high, average, and low percentage utilization.
Table 19. Port utilization information
Value Description
High The high percentage of data communication through a port over a
period of time (measured in seconds).
Average The average percentage of data communication through a port over a
period of time (measured in seconds).
