Grace state and pacing in link aggregation

摘要

In one embodiment, one or more indicia of stress are monitored. Based on the one or more indicia of stress, it is determined a stress condition exists. In response to the stress condition, one or more link aggregation actors and partners are caused to enter a grace state for a grace period. While the one or more link aggregation actors and partners are in the grace state, link aggregation formation is paced on a plurality of links by delaying formation of one or more new link aggregation groups on the plurality of links until a hold is released. Upon expiration of the grace period, the grace state is exited.

1. A method comprising:
monitoring, by a network device, for one or more indicia of stress; determining, based on the one or more indicia of stress, a stress condition exists; in response to the stress condition, causing one or more link aggregation actors and partners to enter a grace state for a grace period, the one or more link aggregation actors and partners logically aggregate links to form one or more link aggregation groups for respective network devices; while the one or more link aggregation actors and partners are in the grace state, pacing, by the one or more link aggregation actors and partners, link aggregation formation on a plurality of links for the respective network devices by delaying formation of one or more new link aggregation groups for the plurality of links until a hold is released and periodically releasing the hold on a selected size of subsets of links for the plurality of links to support formation of one or more new link aggregation groups, the selected size of the subsets of links being increased or decreased in response to changes in severity of the stress condition; and exiting the grace state upon expiration of the grace period.
