The engine menu within the ISIS Management Console flashes a yellow warning triangle
notifying you that a 10-Gb Link Aggregation link has changed. The specific engine displays a
yellow warning circle, and the Switch Blade Status displays “1 Error(s).” Details on the engine
switch displays a status of “Link Warning.” You can then open the Switch Agent page via the
“info” button on the engines details page, and look at the Port Status page to verify the 10-Gb
Link Status.

This failover feature functionality can be disable in switch agent page.
Recommended Topologies
For the best performance in stacks with two IXSs, the link aggregation members need to be
evenly distributed between the ISSs that are connected to each IXS. For example, with a four link
group; two are connected to ISSs that are connected to IXS A, and the other two links are
connected to ISSs that are connected to IXS B.
Supported Functionality
From the Link Aggregation menu in the switch agent, you can:
•
View current settings — This displays the current link aggregation configurations, showing
all currently configured groups. The user may also modify a group or delete a group from
this page.
•
Create a new link aggregation group — This allows you to define a new link aggregation
group.
•
Enable or disable link aggregation configuration — This allows you to disable or enable the
current link aggregation configuration. The configuration is preserved.
•
Restart the link aggregation configuration — This allows you to request that the stack restart
its link aggregation configuration. This removes and rebuilds the link aggregation groups as
defined in the current configuration.
•
Delete the link aggregation configuration — This disables link aggregation and removes any
existing link aggregation configuration. The configuration is not recoverable. This can be
used to set link aggregation settings back to factory defaults.
Other Functionality
•
Every time a switch is introduced to the stack (by connecting the stacking cable) or removed
from the stack (by disconnecting the stacking cable), the link aggregation software clears the
link aggregation information from the switches and re-programs them again.
•
If the switches are being programmed with link aggregation information for the first time,
link aggregation needs to be enabled. This is done by clicking on “Enable or Disable link
aggregation configuration.”
