Quotas for your Network Load Balancers - Elastic Load Balancing
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Quotas for your Network Load Balancers

Your Amazon account has default quotas, formerly referred to as limits, for each Amazon service. Unless otherwise noted, each quota is Region-specific. You can request increases for some quotas, and other quotas cannot be increased.

To view the quotas for your Network Load Balancers, open the Service Quotas console. In the navigation pane, choose Amazon services and select Elastic Load Balancing. You can also use the describe-account-limits (Amazon CLI) command for Elastic Load Balancing.

To request a quota increase, see Requesting a quota increase in the Service Quotas User Guide. If the quota is not yet available in Service Quotas, use the Elastic Load Balancing limit increase form.
