When this conÞguration is used, only one moduleÕs SmartTrunk Group will be
active. The second path will block and serve as a backup to the currently active
path. (The active trunking path will be determined by the module providing the
lowest path cost.)
Refer to the release notes for image-speciÞc restrictions while using
SmartTrunking.
NOTES
The only time path cost is calculated is when a port is added or removed from the
trunking group. While the trunking group is operational, losses of link or PLAP
on a port will not result in path cost recalculation. In order for a redundant group
to become active, the entire primary group must become inactive or disabled.
NOTE
